Don came across a thriving row of grevilleas (Grevillea ‘Robyn Gordon’). When the gardener, Brian, planted the grevilleas, he followed two important gardening principles:
Raised garden beds provide good drainage, which is essential for most garden plants, and particularly important if you are growing Australian native plants. Many natives don’t like having ‘wet feet’, which makes them susceptible to diseases such as root rot.
It is usually better to improve your existing soil than to add bought soil to your garden. Even heavy clay can be improved with additives such as well-rotted manures, mulch, compost and gypsum or lime. It is also important to cultivate heavy soils when they are damp and crumbly, not wet and sticky.
