Q Why have my earthworms disappeared?
Patricia Hall, by email
A BOB SAYS If your soil is dry, the worms may be deeper in the soil awaiting moister conditions. But even if they have died, there may be eggs in the soil. As long as you aren’t growing acid-loving ( ericaceous) plants, give the soil a dressing of garden lime, as worms love this. Next, apply a mulch of wellrotted manure, leaf mould or garden compost. Add a dressing of seaweed meal or blood, fish and bonemeal in spring. Keep the soil moist and regularly sprinkle a few grass clippings sparingly onto the surface, and I guarantee the worms will return.
Earthworms love moist soil that contains plenty of organic matter
