Obviously weeds must be kept at bay and there is no miracle cure. The way to tackle the problem is to use a number of interlinked tasks. At soil preparation time the roots of perennial weeds should be pulled out and destroyed. When getting the new garden ready for planting it is necessary to remove all the weed seedlings which have appeared on the surface. Mulch around the newly planted garden in June. The vigorous growth of your plants should suppress most weeds by midsummer and any that come through should be hand pulled.
A mulch is a layer of bulky organic matter placed on the soil surface around the stems. Suitable materials include moist peat, well-rotted manure, leaf mould, shredded bard, crushed stone, compost and well-made garden compost. A two-inch layer spread on moist soil around plants in June will keep annual weeds in check and there are additional benefits. The soil is kept moist in dry weather, soil structure is improved and some plant foods are provided. Fork the mulch into the soil when the plants are removed in late autumn.
