The term ‘wicking’ refers to the water reservoir in the bottom of the boxes below the soil; water ‘wicks’ up from this reservoir through the soil to the plant roots. It is a way of targeting water at the very part of the plant that needs it most – the roots – and reducing the evaporation that occurs when we water from the top of the soil. It is a great system for hot and dry areas, so for much of Australia in summer!
These wicking boxes are excellent for soft-leaved herbs like basil or coriander, as well as lettuces, chervil or Asian greens. Try as many plants as you like and see for yourself what grows best.
