The best time to trim and prune plants and trees is when they are fully dormant in late Winter, so August is the best month! Here are a few tips and techniques to follow to give your trees the best chance for spring.

1. Most plants need a certain amount of light to produce new growth, flowers or fruit. By crown- thinning, reduction or lifting of trees light can reach plants under trees and will create favorable growing conditions for gardening under trees. There will be better airflow after thinning, reduction or lifting which will reduce moisture build-up in soil in wet conditions. More light will also reduce the risk of certain diseases attacking plants in shady, damp conditions.

2. The best time to prune and trim trees is in July and August for most trees. Because deciduous trees are empty by then and evergreens are a lot thinner in winter it enables the tree felling professional to see better which branches to remove or thin when cutting is done. Pruning and trimming can be done throughout the year, but remember that by cutting flowering trees just before flowering, the flowering time will only be in the following season as flower bearing stems may be removed when cutting is done. Winter gardens are mostly devoid of lush growth and flowers and with the activity of cutting there will be less damage to foliage and precious flowers.

3. Crown-thinning refers to the thinning out of the crown of trees where certain branches are removed to let dappled light reach the surrounding areas under trees. On average about 25 % more light can be let into these areas.

4. Reduction refers to the removal of long branches in a tree or to shape trees. By reducing the length of branches more light can be brought to under the trees. Some gardeners are eager to “top” the tree lower. This usually results in a lot of lateral growth forming and in the end there will be denser growth and more shade. The professional tree feller will usually cut only to a fork or to against the stem. He will also take into account the shape and balance of the tree when cutting.

5. Lifting refers to lifting or crown lifting of lower branches growing too close to the surface. By removing such branches, light or even direct sunlight can be brought into previous shady spots. Your professional tree feller will again take into account the shape and balance of the tree. Crown lifting leaves the tree with a narrower profile and works well where a lot of mature trees are planted close together. By lifting them, previously dark, moist areas can be rejuvenated with the extra light brought in.

Help Save our Planet by saying NO to Single Use Plastic!

I’m sure, by now, you have seen a meme or an article on the internet about straws and their devastating effect on our environment. Single Use Plastic, specifically straws have been getting a lot of media attention.

Today we will discuss single-use plastic and why it such a bad thing for us and our environment.
Single-Use Plastic, or disposable plastic, is used once and then thrown away or recycled and these items can include things such as plastic bags, plastic cutlery, straws, water bottles and food packaging.

Only 10% of all plastic that is produced, is recycled and we produced roughly 300 million tons worldwide every year. Petroleum Based Products, which is non-biodegradable, takes anywhere from 90 to 1000 years to degrade and they normally end up buried in landfills or the plastic gets broken down into microscopic pieces en route to the ocean. During this process, toxic chemicals are released which eventually makes its way into our food and water supply, not to mention the direct impact this has on plants, animals and marine life. We are rapidly poisoning ourselves and our home planet with plastic.

We got used to having these ‘convenient’ plastic products in our lives, but we have many more options available to us these days. We can use canvas or paper shopping bags, paper or reusable coffee cups, glass bottles and paper or bamboo straws, but we still insist on using plastic.

Let us just look at the one item that started this trend across the world – the plastic straw.
The world uses 500 million drinking straws per day. Some are recycled, but most of them are discarded and ends up in our oceans. One million marine birds die every year from ingesting straws. In one example, when the stomach contents of a deceased sea turtle were examined, scientist found over 100 plastic straws in its digestive system, not to mention plastic bags, cigarette butts and lids.

The recent trend to ban straws is gaining momentum with many companies adopting this policy across the world. In South Africa, Ocean Basket has banned the use of plastic straws in all of their restaurants, and you will not find a single plastic straw at O.R. Tambo Airport. All food kiosks inside the Two Oceans Aquarium are petroleum-based plastic free. In the US, Starbucks has announced that they have developed a new lid that does not require a straw for their products.

In Seattle, USA, they have completely banned straws and plastic packaging outright and in 2017 Kenya banned the use of plastic bags completely.
Yes, straws are necessary for some people, especially for those with disabilities, but the straw does not need to be made of plastic.

The History of the Straw

Straws were originally made for beer, back in the day, when the filtering process was not as sophisticated, to avoid lumps. These were, however, completely reusable.

Interestingly enough, the first recorded straw in history is 4600 years old and was used by Queen Puadi of Ur – this one was also re-usable. In 1888, Marvin Stone invented the disposable straw, but incidentally, it was made of paper. It wasn’t until the mid-1970’s that we started producing and using plastic disposable straws. Why? Because plastic was cheap and we didn’t know what impact it would have on the environment, or rather, we did not care. We are now suffering the consequences of our short-sightedness.

To get involved in the above mentioned environmental campaigns, take a look at the #StrawsSuck Campaign.

The Humble Honey Bee – What will happen if they disappear?

The humble honeybee, known for creating the sweet nectar we call honey. In recent years, bees have been discussed in the media very often and many believe that they are endangered. What will happen if they go extinct?

Albert Einstein is erroneously quoted as saying: “If the bee disappeared off the surface of the globe, then man would only have four years of life left.” In truth, no one knows who said this first, but it does shed some light on just how important the honeybee is.

A healthy interaction between plants and pollinators is vital to maintaining both plant and pollinator communities. Bees, as one of the most common and important pollinators, play an important role in maintaining this interaction and ensuring that pollen is transferred from anther to stigma, ensuring the propagation of plant life.

Let us explore pollination and it’s importance and look at the role of bees in the pollination process.
Pollination is the transfer of pollen grains from a flower’s male anther to another flower’s female’s stigma. The purpose of this process is to fertilize the flowers, thereby producing new seeds and allowing more plants to grow (this natural process is called propagation). Even though there are some flowers that are able to develop seeds without this fertilisation process (called self pollinators), some plants and flowers require help through cross-pollination and a pollinator, like a bee, butterfly or a bat, who needs to carry pollen from flower to flower, does just that.

Pollination is crucial for our natural ecosystem, as well as for artificial production environments such as farms because it directly affects plant and crop propagation. From an agricultural perspective, roughly a third of the food consumed by humanity comes from animal-pollinated plants. Should something cause crop pollinator populations to decline, it could have a devastating impact on crop production.

An estimated 25,000 bee species have been identified worldwide, each playing an independent and indispensable role in our environment. Bees are considered to be the most common and important biotic pollinators of angiosperms. The reason for this is that they are operatively and diligently able to gather pollen for themselves and their larvae. Bees are also significant in the pollination process of wildflowers and crops. Moreover, in northern temperate regions of our planet, like the U.K for example, bumblebees supply almost half of all the pollination.

South Africa is home to two sub-species of honeybee – Apis mellifera Scutellata (or “African bee”) and Apis mellifera Capensis (or “Cape bee”). Mike Allsopp of the Agricultural Research Council, said, in an interview with the Mail and Guardian, “We are somewhere between a crisis and a catastrophe,” as he has been warning of a collapse of African Bee Colonies for some time now. He further states “Bees are more important than any other domesticated animal because they are indispensable when it comes to our food security.”

Certain areas of the world, such as central Europe, the United States of America and Mexico, have been experiencing a significant decline in honeybee populations. The most well-known is the Apis mellifera, but Americans refer to them as Africanised Honeybees. Factors such as the effects of climate change, a decline in genetic bee colony variation, parasites, infections, the limitations on bee trade, and the use of insecticide on crops all play a role in this decline.

But, what contributes to this decline?

1) Pesticides

A common pesticide used by farmers in agriculture is a chemical called neonicotinoid. Neonicotinoids are a class of insecticides with lethal effects. It is widely used in gardens and on agricultural crops to control pests. When exposed to this toxic chemical, some species suffer severe consequences, such are impaired smell and memory, reduced foraging, difficulty in flying, curbed procreation and increased susceptibility to diseases. Neonicotinoids work by dissolving it in water. If the pesticide gets into our water supply, the substance will steadily work its way into waterways by means of agricultural runoff. The flowers then soak up the water, exposing its stems, leaves, pollen and nectar to the toxins.

Studies show that queen bees that are exposed to this pesticide, are 26% less likely to lay eggs, reproduce or start a new colony and therefore, it causes a significant decline in the bee population – even result in the extinction of wild bee populations in some areas.

2) Bacteria

A very common and dangerous bacteria killing millions of bees is the American foulbrood disease. This serious disease is ingested by bee larvae in colonies and the bacteria grows inside them until it kills the host. This eventually kills the entire hive, leaving nothing but corpses carrying millions of infected spores. In due time, new bees will occupy the hive and they will suffer the same fate.

Thus far, South Africa’s honeybee population has been rather resilient to most diseases and outbreaks that have affected our bee population. However, this view seems to be rapidly changing. The deadly American foulbrood outbreak hit South Africa in 2015 and caused bee colonies in the Western Cape to decrease by 40%. Big producers, such as the United States, commonly treat this disease with antibiotics. The same practice can be followed here to keep the disease from spreading.

What can we do to prevent this?

1. Managing pollination

Currently, the only pollinator being managed in South Africa is the native honey bee. Managing honeybee colonies carries several advantages and, unfortunately, some disadvantages. The prime advantage extends to the foraging habits of the honeybees. These habits enable them to pollinate various crop species. The disadvantage to their transport capabilities is that they gather pollen which they then moisturise with nectar and honey, then store on their hind legs, resulting in the restricted availability of pollen available for pollination. Moreover, they are highly vulnerable to pesticides, diseases and parasites – posing a threat to their commercial use, requiring advanced management strategies. This is the reason why a honeybee is considered one of the lesser pollinators among the bee species. It is vital that other management options using native species are explored.

2. Support local and organic production

Organically produced fruits and vegetables are grown without the use of pesticides, which is advantageous for the environment and the bee population. Even though they are a bit more expensive, it is recommended to rather buy organic produce as the extra cash contributes to the health of the bees and better working conditions for the farmers.

It is also advocated that one buys humane and locally produced honey. When purchasing honey from hives on small and local farms, it contributes towards local business and supports the fair treatment of bees.

3. Create a Honeybee Haven

A home-made garden filled with bee-friendly plants and flowers can go a long way. This will help feed the local bees, especially in urban areas where there are little to no plants and flowers to pollinate. This will also increase the biodiversity of plants in that area. Create a beautiful, vividly colourful garden – it should be easy to encourage your peers to follow your lead, once they see your masterpiece.

4. Collaborate with Others

Building up a complete new beekeeping-farm can take time and a lot of patience. Sometimes it would just be more effective to take over an existing site. In this regard, it is important for farmers and beekeepers to collaborate and work together, not only in support of a build-up and insurance that it is done properly but also to communicate with one another on what insecticides should and should not be applied.

5. Urge your government to pass legislation

Specific and stringent legislation is required to prevent a further decline in our bee population. It is important for the government to step in and enact legislation that will protect the bees, test honey and imported honey products, to have educated bee-keepers and help them to manage the bees efficiently. It is our duty to urge the local municipalities to do so.

The significant role that bees play in our environment cannot be overstated. As the human population increases, so does the need for food. Bees help produce our food. If bees go extinct, our world will most likely become a harsher, much less vibrant place. Let us help the Humble Honeybee so that they can, in-turn, help us!

Tips for Planting Happy, Healthy Trees

Trees are long term investments and bring beauty, shade and fresh air to us all. You may think that planting something means you stick it in the ground, cover it with soil and water it and hope for the best, but if you take small steps during the planting process, you can give your trees the best start. You will definitely reap the rewards at a later.

Finding the Trunk Flare

The roots of a tree need to be watered, but they also need access to oxygen, and planting a tree’s roots too deep can cause the roots to slowly suffocate. Planting a tree too deep can also lead to the development of circling roots which can girdle and choke the tree as it grows.

To ensure that the tree is planted at the right depth, you can use the trunk flare as a guide. Take a look at a tree that has grown naturally in the landscape, and notice the area where the base of the trunk gradually widens or flares out just as it enters the ground. This is generally called the trunk flare, or the root collar.

You need to plant your tree so that the base of the trunk flare is right at the surface of the soil or slightly above in dense soil.

So, it’s best to ignore the old advice of simply measuring the height of the root ball to see how deep to dig the hole. Rather go by the trunk flare.

You also may want to set the root ball on undisturbed soil to prevent the tree from sinking down into the hole as the soil compacts again, and covering the trunk flare.


Make the hole wide

This is done so that the soil around the hole can be easily penetrated by the roots. This is especially necessary with more dense soil such as clay where the sides can be slicked over with a hard layer, making it difficult for the roots to push through the soil.


Setting the tree in the hole

At this stage, you may want to loosen and spread the roots on the outside of the root ball before setting it into the hole, but it is important to keep the root ball intact. If you notice any roots that are growing around the root ball or that are kinked, trim them away.

Be very careful with the root system as you set the tree into the hole. Breaking the roots in the root ball can have serious, life-threatening consequences for the tree.


Use native soil to fill the hole

At this stage, you may think that adding fertilizer and organic material to the soil is a good idea, but the tree will do much better with the native soil that you dug out. If you fertilize the native soil, the roots will stay within this pocket of hospitable soil, and will not cross the boundary into the native soil and this will ultimately affect the overall health and longevity of the tree.

Stake only if absolutely necessary

Most gardeners think that a stake is imperative when planting a new tree. The natural movement of an unstaked tree helps it to develop a stronger trunk and a more robust root system, so staking a tree actually causes more problems than you may think.


You can spread mulch about 5 to 10 cm deep over the root zone to help keep moisture in the soil. Remember to make it into a doughnut shape and do not cover the trunk itself with mulch as this could cause rotting of the trunk amongst other problems.

Keep your young tree well watered during its first season in the ground – but take care not to over water. Just ensure that the water soaks through the entire depth of the root ball.

(Part 2) The Life Cycle of Trees and How to Care for them at Each Phase

This week we explore the more mature stages in the life cycle of trees.

  • Adult/Mature

As soon as a tree starts to produce fruit and flowers, it is no longer classified as a sapling and this is the time of it’s life in which it is most productive. The length of this phase depends on the species of the tree.

In this stage of the life cycle, caring for the tree changes. It is a good idea to regularly inspect your trees for diseases, pests and branches that may pose a danger to you or the tree’s health.

During dry periods, it is still important to deep water your tree. Although the tree is now able to withstand longer periods without water, it is still a good idea to deep water the tree at least once a month. You will also need to prune regularly. If you are not sure how or where to prune, we suggest calling a professional tree care specialist.

Be sure to mulch regularly, but be more cautious with fertilizer as a healthy tree is most likely able to draw essential nutrients from the ground. Test the soil first to avoid harming the tree with too many chemicals.

  • Ancient Tree

An ancient tree is not usually identified as Ancient by it’s age, but rather by it’s characteristics since the life span of a tree depends on the species. The characteristics will be, for example, a tree with a small canopy and a hollow trunk.

Once again, we suggest regular tree inspections to check for disease, pests and the need for pruning.

Keep in mind that the tree is not as supple and strong as it used to be in its youth, so be aware that you could seriously damage your ancient tree by drilling into the tree or hanging items from it, like tyre swings, etc.

  • Decaying Tree (Snag)

This is the final stage of a tree’s life cycle and includes trees that are decaying as well as dead trees that are still standing. The tree itself will no longer grow, but the usefulness of its trunk to the environment around it has not yet diminished. The dead wood can now provide homes for wildlife and insects and can also be a source of food for them.

A snag does not require a lot of care as the tree is essentially dead or dying.

The Life Cycle of Trees and How to Care for them at Each Phase (Part 1)

Just Like humans, in fact, just like all living things, trees have a life cycle. This article will examine these stages and suggest how you should take care of your trees in each stage of their life cycle.

  • Seed

Seeds are a means for trees to ensure that the next generation of the species is spread and propagates – to ensure that the species continues to survive.

The seed contains all the resources needed for it to survive on its own, for a period of time so that it can reach a safe place to germinate.

The best time to sow seeds is in Autumn but you need to ensure that they are planted or sowed at the recommended depth. If they are planted too deep, they may not sprout and if they are planted too shallow the roots won’t take hold and the seedling will wither.

You should ensure that you use a good soil that drains well and place the container in a sunny spot. Ensure that you keep it moist but not wet, as too much water could cause decay and the seed will not sprout. The environment should also be quite humid, so we suggest that you cover the container in a plastic tent with some holes to allow air circulation.

Once your seed germinates, move it to a brighter location – you may need to keep it indoors until you are ready to plant it, but ensure that the plant gets plenty of sunlight.

  • Sprout

The seed has now fallen and needs to secure itself – this happens when the primary root emerges from the seed in order to anchor it and to provide the growing plant with water.

Once the primary root is secure, the embryotic shoot emerges which will then appear above the soil.

  • Seedling

A tree is considered a seedling until it is about 3 ft or 1 metre tall. This is the stage of the tree life cycle when it is most at risk of disease or damage. The seedling would be called a whip if it does not have any branches.

It is best to uproot, store and transplant trees during their dormant phase because they are more able to resist stresses during this phase. This is usually during the Autumn and Winter months.

You need to ensure that the roots remain properly moisturised as the root tips desiccate from lack of moisture. The root tips are extremely important for the tree as this is where new roots will sprout from.

Try to handle the seedling as little as possible.

Choose a spot that is well protected from most of the elements in your garden so that the tree can stand a fighting chance of survival.

  • Sapling

Once a tree grows higher than 1m it is considered a sapling, but the duration of time for which the tree is considered a sapling depends on the species.

Water is much more important than fertilizer in the first two years, so make sure that you keep the soil moist, but not wet. Even though your tree is at it’s weakest just after planting it and will need a fair amount of water, you can still over water it and you could lose your tree. To check if it has enough water, you can dig a small trench around the sapling and checking if the soil is still moist. If this is dry to the touch, your plant needs water.

Ensure that you use the deep watering technique with saplings that are planted in your garden. Shallow watering will result in surface roots forming which are too weak to support the young tree and will make it more susceptible to disease.

Quadrastichus Mendeli: Is this species a friend or a foe?

FABI (Forestry and Agricultural Biotechnology Institute) has recently discovered a natural enemy of the invasive wasp species, Leptocybe Invasa in South Africa.


Leptocybe Invasa

The pest Leptocybe Invasa is native to Queensland, Australia, but has spread to Africa, Asia, the pacific, Europe and Latin America. In fact, any country that has Eucalyptus trees can fall victim to this gall wasp.

In South Africa, Eucalyptus plantations are being infested by this pest. They insert their eggs into newly sprouted leaves, petioles and stems of the Eucalyptus tree, and, as the tree develops, the larvae grow and deforms the attacked area. This deformed mass of tissue is called a gall, hence the term, gall wasp.

Each gall has multiple chambers and each chamber hosts a developing insect, drawing nutrients from the deformed plant tissue surrounding it. At a high enough infestation rate, the growth of trees can be stunted. They can even be killed. This insect can cause major devastation of the Eucalyptus tree population resulting in various management strategies like the selection and deployment of resistant eucalypt genotypes and the introduction of biological control species like the Selitrichodes neseri.


Quadrastichus Mendeli

Having this little wasp in South Africa is good news. It is hoped that the Q.Mendeli will control and eventually end the spread of Leptocybe Invasa.

The Q. Mendeli is indigenous to Australia, is about 1mm and directly attacks the developing L. Invasa larvae. The Q. Mendeli was deliberately introduced by Israel and India and they have seen very good results in the control of the L. Invasa.

The situation is being monitored buy collecting samples of galls for research on a regular basis, but for now, all we can do is wait for the Q. Mendeli to do it’s job!

Organic Christmas Trees

December is fast approaching and the Christmas feeling is already in the air. Why decorate the same old way with that same old plastic tree?

There are some trees and shrubs that can substitute as a Christmas tree and once Christmas is over, it can be planted in your garden, or it can be kept in it’s pot ready for next year’s use. You can even take the DIY one step further by using seed pods and other organic material to make decorations. Get creative with paint, glitter, beads and other fun things and paint those cones and seed pods that you pick up around your garden!

Not only will you be saving the planet by reducing the use of plastic but you can also save money!

There are some Indigenous Tree Species that would make lovely Christmas Trees. These include:

  • The Yellowwood Tree (Podocarpus Henkelli)

This tree is often considered to be South Africa’s National Tree – it has glossy, dense, drooping leaves and a neat canopy. The branches are strong enough to hold decorations and the tree doesn’t grow very fast, so you should be able to use it as a Christmas Tree for many years. In a natural habitat the tree can reach between 20 and 30m in height, but it will be just fine in a container as well.

  • Outeniqua Yellowwood (Podocarpus Falcatus)

When young, this evergreen tree has the traditional conical Christmas Tree shape and can permanently be kept in a container due to its slow growing properties. In a natural habitat, the tree can reach up to 12m.

  • Real Yellowwood (Podocarpus latifolius)

This is an evergreen, frost hardy tree with blue-green foliage that can be grown and kept in a container for many years.

  • Cape Gardenia (Rothmania Capensis)

This is one of the most attractive indigenous evergreens that has glossy dark green leaves and flowers from December to February.

  • Cheesewood (Pittosporum Viridiflorum)

This tree only reaches about 7 metres in height which makes it great for a small garden or container. It is frost hardy and has glossy dark green leaves that forms a neat canopy.

  • Blue Guarrie (Euclea Crispa)

This member of the Ebony Family is a neat, upright tree with a dense round canopy of dark bluish green leaves. It has a rusty to dark brown bark, often covered in lichen. This evergreen tree is ideal for smaller gardens and provides shade all year round because of its frost hardy and wind resistant properties. In summer, the sweet fragrance of the yellow bell-shaped flowers attracts butterflies and beautiful birds.

  • Mountain Cedar (Widringtonia Nodiflora)

This tree canopy is conically shaped with needle-like leaves – it looks the most like a traditional Christmas Tree. The tree is frost and drought resistant which makes it more likely to thrive in our tempestuous South African Weather conditions.

Caring for your Trees this Summer

Caring for your trees during the summer months is just as important as during any other season. This article will look at a few tips and techniques you can use to take care of your trees during the long, hot summer!


The best time for mulching trees would be spring time, but you will also be able to successfully mulch your trees in summer and still reap many of the benefits. Mulch keeps your soil temperatures cool by helping to conserve the moisture in the soil, and suppresses the growth of weeds. Keep in mind that you shouldn’t mulch against the trunk of the tree as this can cause the trunk to rot over time. Rather make a donut shaped mulch layer around your trees.


South African summers can get quite hot, so it may be necessary for you to water your trees regularly, especially if the tree is young or newly planted. Trees need, on average, one inch of water per week, and it is much more effective to water a tree less frequently, but you need to make sure that the water reaches deeper into the ground to reach the deep roots of the trees.


Just like humans, trees need nutrients to support leaf and shoot growth, and to fend off diseases and pests. Trees growing in urban areas or high stress areas will need more fertilizer than trees growing in natural areas


Pruning trees is as much an art as it is a science – this is why you should try to leave it up to the professionals. You should try to limit your pruning to the dormant season, but sometimes it is necessary to prune your trees in summer. You should remove any branches or leaves that are diseased, damaged or dead. Flowering trees should only be pruned in the early summer, after they finish blooming.

Tree Pest Inspections

You should always keep an eye on your trees, by examining them frequently throughout the summer to check for pests and diseases. Most insects are not harmful to trees but some can be devastating to the health of a tree. Inspecting your trees regularly will ensure that you catch any potential infestations early, and will prevent the loss of precious, oxygen producing trees.

Storm Damage

Summer rain storms can cause damage to trees and property, and it is important to assess the health and strength of your trees after every heavy storm. You may need to consult a tree care specialist to assess the safety of large trees. You could also brace and/or secure weak limbs with cables, if it is not necessary to completely remove the limb.

To Burn or Not To Burn

Spring time has arrived in sunny South Africa and this means it’s time to braai! South Africans love to enjoy the beautiful weather and environment we are blessed with by spending time outside with friends and family around the fire.

Contrary to what you might think, not all wood should be used in a fireplace or a braai. There are some risk factors to consider when choosing your fire wood to ensure that you, your friends and your family stay safe and healthy while enjoying the great outdoors.


Never use the following:


  • Green Wood

When a tree is cut down, the wood needs to be left out to dry, or season, for an extended period of time (more than 9 months is best). A newly felled tree will still have tree sap and water stored within its branches.

Freshly cut fire wood is very difficult to set alight, it produces less heat and a lot more smoke. The wood will also bubble and pop as it burns away the moisture in the wood.

Chimney fires may be caused by burning the wet wood of certain species of tree. The smoke could contain a high concentration of creosote, which is a flammable substance that collects in chimneys as the smoke escapes. Evergreen trees give off more creosotes than most.

Green Wood will have firmly attached bark that is still sticky with sap. Seasoned wood will weigh less and will make a cracking sound if you hit it with another piece of wood.


  • Non-local Wood

If you live or are visiting an area which is affected by an invasive species, you should take care not to move the wood outside of this area.

The spread of invasive insects and diseases is mainly caused by firewood that travels outside of the affected area. New outbreaks almost always start in and around camp sites or public braai areas where firewood is often used.


  • Soft Wood

Soft wood like Pine, Fir or Cypress are soft woods that burn fast, does not form many coals and causes a lot of smoke and soot. If you are using a fireplace or chimney, you may want to avoid wood that is prone to producing soot.

You can use seasoned soft wood for outdoor fires, but cooking using soft wood may become difficult as the wood does not form many coals.



  • Driftwood

Salt Water Drift wood becomes saturated with salt, and burning this can release harmful chemicals into the air. Salt contains Chlorine which can burn away mucus membranes in a condensed gaseous form. The smoke from driftwood can also be corrosive that can damage your fireplace or braai.


  • Poisonous Wood

Any wood that has the word ‘poison’ in its name should never be burned as it will release an irritant called Urushiol into the smoke. This will cause major respiratory problems and can be life threatening in some cases.


  • Oleander or Ceylon Rose (Selonsroos)

Oleander is an invasive species in the South African eco-system, so you may think it will help our eco system if you burn these plants, but every part of the Oleander shrub or tree is extremely poisonous. The sap also irritates the skin. Burning any part of this tree will release carcinogens into the air which is harmful to breathe in. The wood should never be placed near food either.


  • Treated, painted or pressure treated wood

Even though Brands Tree Felling does not deal with or produce this type of wood, we think it is important to mention.

Burning wood that has been treated, painted or pressure treated will release harmful chemicals into the air. This can lead to major health problems for the people around your fire, and for people eating the food prepared on this fire.

Pressure Treated Wood can be identified by its greenish or reddish hue and the perforations on the surface.

Plywood is also not suitable for burning as burning the glue used in the manufacturing process releases harmful chemicals into the air.

Milled Lumber may be treated with polyethylene glycol to make it dry faster.


  • Big Pieces of Wood

If the firewood is too big to fit into your fireplace or braai, it is not suitable. Large pieces of wood can fall out and set alight the surrounding areas.


  • Endangered Species

Needless to say, burning wood from an endangered species would be a tragedy.

For the comprehensive list of the protect tree species.
