Keeping Weeds at Bay
Bare patches of soil will quickly be colonised by both annual and perennial weeds, so a well-stocked border is less likely to support a thriving population of these pesky plants. If you have gaps, plug them by planting ground covering plants. Alternatively mulch bare soil with a thick, 8cm (3in), layer of bark chippings, well-rotted manure or leaf mould in the spring. Not only will this prevent weeds from growing, but it will help to retain moisture in the soil. If you have a large area of bare soil, such as an unused patch at the allotment, cover with plastic, landscape material or even old carpet to prevent weeds from germinating.
