The Working for Water programme – introduced through the Department of Water Affairs and Forestry – is a staunch fighter against alien invasive plants in South Africa.  It is estimated that around 10% of our country is covered with approximately 9000 species of alien invasive plants, which steal water, nutrients and sunlight from our native flora.

The Working for Water programme was initiated in 1995 and has since then cleared out more than a million hectares of alien invasive plants.  It works in conjunction with the Departments of Agriculture, Trade and Industry, and Environmental Affairs and Tourism, as well as, local governments and communities.  Around 20 000 people are trained and provided with jobs every year, due to the Working for Water programme.

This programme uses four methods of clearing and controlling areas which have been invaded by alien plants, namely mechanical (felling, burning and removing), chemical (environmentally safe herbicides), biological (species-specific diseases and insects), and integrated methods, which combines all of the above.

You can do your share of working for water in your own garden, by planting only indigenous gardens and by employing environmentally friendly measures in dealing with pests and diseases on your plants. 

A water wise garden consists of plants that do not require a lot of watering.  These plants are normally indigenous plants, which can survive on rainfall and do not need additional watering.  Succulents are also very water wise plants and look beautiful when planted in masses. 

Hard landscaping features, such as sculptures, trellises, wooden decking, cobble lines, stepping stones, cement screed blocks, feature walls, garden benches and other exterior décor will decorate your garden and requires no water.  Different textures will add dimension to the garden lay-out.

By reducing your lawn area, you will also save on water.  Mulching – layering bark chips, hay, pebbles or grass cuttings – will keep the soil around your plants moist for longer periods and therefore require less watering.

When you have a drip-irrigation system installed, you will also save water.  You can set your irrigation system to water the garden at certain times of the day, such as early morning, when the sun will not just evaporate all the water.

Even weeding regularly will make your garden water wise, as all these unnecessary plants also use a lot of water. 

By using organic fertilizers in your garden, you will be applying responsible measures to ensure that your plants are healthy and grow to their best potential.  You will also be contributing to the fight against soil and water table contamination. 

Organic fertilizers, for instance raise the nutrient content in your garden soil, which feeds your plants and assists the roots of your plants in getting optimal nutrition from the soil.  The three most important nutrients needed by your plants are phosphor, potassium and nitrogen.

Another advantage of using organic fertilizers is that it enhances your soil composition and improves water retention, which in turn does its part in combating drought.

By using organic pesticides in your garden, you will be applying responsible measures to ensure that garden animals, birds, insects, reptiles and amphibians will not suffer poisoning. You will also not harm your pets and you will be contributing to the prevention of soil and water table contamination.

The black wattle tree is a dangerous alien invader.  It is an evergreen tree and can grow up to 30 meters in height.

These intruders were introduced into South Africa between 1858 and 1864.  it is not sure whether the first black wattle trees were planted in the Cape Town Botanical Gardens (1858) as decorative trees or in the present-day KwaZulu-Natal near Camperdown (1864) as commercial trees. 

Due to its high tannin content (around 30%), the black wattle was planted commercially to be used in tanning leather.  The wood was also used for firewood, building materials and as wood chips.

Unfortunately these exotic trees – native to South-East Australia – have started growing profusely outside commercial plantations, along water courses and roads.  They tend to grow in dense copses, especially after a fire has passed through the area.  Because these trees were planted outside of their natural habitat, they do not have to contend with their natural enemies, which control their numbers.  These trees steal water, nutrients and light from our indigenous plants and trees, and therefore replace our native flora.  Especially our fynbos areas are threatened by the black wattle.

The black wattle has been declared an invader plant throughout South Africa, except in areas where they are commercially planted.    These commercially planted trees should be monitored, however, and be prevented from spreading out of the plantations.

Black wattles reproduce by their seeds, which can remain dormant, yet fertile, for a period of 50 to 80 years.  These seeds do not germinate immediately, and can gather quite thickly under the trees.  Should a wild fire spread through the trees, all of the seeds will germinate simultaneously, which causes an even bigger problem.

These trees also re-sprout rather heartily, adding to the level of difficulty in getting rid of them.  Should you fell a wattle tree, you must ensure that you treat the stump with a herbicide, to prevent it from re-sprouting.  As these trees normally flourish along water courses, you need to ensure that you use a registered herbicide and definitely steer clear of diesel-based products, as this will contaminate the water course.

If the trees are still young – seedlings and saplings – you can pull them out by hand, when the soil is wet.  However, if there are very many of them, it is best to use chemical control measures, as extreme soil disturbance will also promote the germination of seeds.

The bottom line is that you should never plant a black wattle in your garden and you should do your share in terminating these plants responsibly to enhance the growth of our indigenous flora.

You should carefully consider the selection of plants for your garden, in order to ensure that you do not plant invasive alien plants. These are plants that are not indigenous to South Africa. They tend to grow faster than our indigenous plants and can easily take over. They also take up precious water, nutrients and light which is more needed by our native plants.

Many of us have invasive exotic plants in our gardens, such as lantana, pipe grass, cat’s claw creepers, privets (ligustrum robustum privet), water hyacinths and wattle, jacaranda, pine and seringa trees. Rather opt for indigenous plants in your garden.

Indigenous gardens are not only less expensive, water wise, hardy and proudly South African, but also very versatile. You have thousands of indigenous plants to choose from, which means you can design your garden in a variety of styles, ranging from tropical to bushveld. Another advantage to indigenous gardens is that you will attract birds, insects and animals to your garden; creating your very own ecosystem in your backyard. You will also be contributing to the preservation of our indigenous plants.

Typical indigenous plants that we use include tree aloes, cape aloes, marlothii aloes, honey suckle, clivias, agapanthus, arum lilies, bulbines, wild garlic, acacia trees, olive trees, white stinkwood trees, and indigenous grasses, such as three awn grasses, thatching grass, buffalo grass, broad-leaved turpentine grass, bristle grass, Natal red top grass, red grass and fountain grass.
