To achieve the best yields and most flavour from your vegetable crops, it is essential to take good care of them. They should be kept clear from weeds and the soil watered whenever necessary. Adding a mulch will help you with both these tasks, as it is an efficient way of suppressing weeds and retaining moisture. You will also need to feed the plants regularly; this may simply be to build up the fertility of poor soils or may be used to increase crop yields.
