Guilt-free gardening

Cherise Viljoen’s suggestions on how to garden in the drought and how to recognize a plant that is designed by nature to survive our long hot summer climate (wind, lack of water, harsh sun)

Choose slower growing, more long lived, hardier evergreens and try avoid soft, thirsty annuals & perennials

Select those plants naturally geared to survive drought:
 - silver, grey foliage: reflects the heat
 - upright, narrow, small leaves or no leaves at all: all if which reduces contact with the hot sun and so stay cooler- reducing their water-loss though evaporation
 - hairy, waxy, firm-structured, aromatic: all designed to also reduce water-loss from the plant
 - succulent: have their own reservoirs of water supply
 - have more underground plant parts and storage organs- like bulbs: Hide from the sun and wind and so reduce water-loss
 - deciduous in summer: grow when the weather is cooler and wetter, sleep when conditions are unfavourable

Waterwise indigenous gardening on the sandy flats

Alice Notten, Chief Interpretive Officer at Kirstenbosch National Botanical Garden, gave an entertaining and informative talk on Waterwise indigenous gardening on the sandy flats. The talk was hosted by the Friends of Meadowridge Common, and took place in the Meadowridge Library - one of several interesting talks hosted by the Friends over the years. Alice Notten is a botanist and horticulturist who has worked at Kirstenbosch for many years, and is known by many for her interesting articles on gardening with indigenous plants on the website PlantZafrica as well as those in Veld & Flora. This is a summary of her talk, with links to the PlantZafrica site, where you can obtain more information on gardening with specific plant mentioned.
When Alice bought a house in Plumstead, she was a bit shocked at the windy, sandy conditions she faced as she had only had experience gardening in the rich, loamy soils of Johannesburg, and then the rich loamy soils of Kirstenbosch where she had lived up to this point. Anyone who has gardened in this area knows the type of soil that she was confronted with: sandy, oily soil that repels water. Alice started off by planting a windbreak around the perimeter, finding Searsia (Rhus) pendulina to be the most successful fast-growing, bushy hedge,
as well as the pioneer Keruboom (Virgilia divaricata and V. oroboides). This is an excellent pioneer tree that will act as a "nursery species" by providing protection for slower growing, more sensitive plants that you can plant around it. Being a pioneer species, the Keurboom will die in about ten to fifteen years by which time the slower growing species will be well established.
Another good hedge plant is Tecoma capensis. It is hardy and colourful and fast growing.
