Caring for Water-Wise Plants

Water-wise plants are an excellent choice for any garden in South Africa. These plants are naturally adapted to the local climate and require less water than other types of plants. However, this does not mean that they are completely maintenance-free. Here are some tips for caring for water-wise plants:

Neglect

Water-wise plants are generally low-maintenance, and they can survive periods of neglect. Overwatering is one of the most common mistakes that gardeners make with these plants. It is important to avoid watering them too frequently, as this can lead to root rot and other problems.

Evaporation

Water-wise plants are also well-suited to hot and dry conditions. However, in extreme heat, water can evaporate quickly from the soil. To prevent this, it is important to mulch around the base of the plants. This will help to retain moisture in the soil.

Groundcovers

Groundcovers are an excellent choice for water-wise gardening. They help to stabilise soil, prevent run-off, and reduce erosion. They also provide a natural mulch, which helps to retain moisture in the soil.

Corms

Some water-wise plants, such as agapanthus, grow from corms. These are underground storage organs that help the plant to survive periods of drought. It is important to avoid disturbing the corms when planting or weeding.

Dry Patches of Soil

If you have dry patches of soil in your garden, water-wise plants can help to stabilise the soil and prevent erosion. They can also help to retain moisture in the soil, which can benefit other plants in the area.

Lawn Replacement

Water-wise plants can be used to replace traditional lawns. This can help to reduce water usage and maintenance. Groundcovers such as thyme or chamomile are a good choice for this purpose.

Flowering Period

When selecting water-wise plants, it is important to consider their flowering period. Some plants, such as aloes, have a short flowering period. Others, such as agapanthus, have a longer flowering period.

Group Plants

Water-wise plants can be grouped together to create a natural-looking garden. This can help to reduce water usage and maintenance. It is important to choose plants that have similar water requirements.

Organic Matter

Adding organic matter to the soil can help to improve its water-holding capacity. Compost and well-rotted manure are good sources of organic matter.

Wilting

Water-wise plants are adapted to survive periods of drought. However, if they start to wilt, it is important to water them. Wilting can be a sign that the plant is not getting enough water.

Hairs

Some water-wise plants, such as lamb’s ear, have hairy leaves. These hairs help to reduce evaporation from the leaves and retain moisture in the plant.

Insects

Water-wise plants are generally less susceptible to insect damage than other types of plants. However, it is still important to monitor them for pests and diseases.

Benefits of Water-Wise Plants

Water-wise plants offer a range of benefits for the water-conscious gardener and are especially relevant in South African gardens, where drought-resistant and indigenous plants are highly sought after. These plants are the hardiest species and can withstand the harsh climate conditions of South Africa.

One of the most significant advantages of water-wise plants is their sustainability. They are well-suited to thrive in regions with limited water resources, making them a vital component of xeriscaping – a landscaping practice designed to conserve water, particularly important in South Africa’s semi-arid and arid regions.

Water-wise plants also require less maintenance than other plants, making them ideal for gardeners who have limited time to care for their gardens. They are also well-suited for structural display and can withstand foot traffic, making them ideal for use in garden beds and along walkways.

In terms of aesthetics, water-wise plants are not lacking. Many of these plants offer beautiful blooms, such as the purple flowers of the Cape Honeysuckle, which can add colour and vibrancy to any garden.

Furthermore, water-wise plants can reduce the need for mulching, which in turn reduces the growth of weeds in your garden. This is particularly important in Gauteng where gardens consume 30-50% of all domestic water used.

Overall, incorporating water-wise plants into your garden is a smart choice for any gardener looking to conserve water, reduce maintenance, and add beauty to their outdoor space.

Conclusion

Water-wise gardening also implements the principles of Xeriscape gardening, which includes using mulch to retain moisture, grouping plants with similar water needs together, and using efficient irrigation systems. This significantly reduces the need to water, saving both water and money.

Furthermore, creating a water-wise garden not only benefits the environment but also adds beauty and diversity to South African gardens. As the need for water grows, so will its price and legislation to discourage excessive use.
