Helen Yemm the green-fingered guru solves Telegraph readers gardening problems. This week: a closer look at worms and the official start of spring.
The wonderful world of worms
Steven Walcott is amazed that his lawn, which has spent an extraordinary amount of time in the past month or so under water, is still alive and, more extraordinarily, he says, so are the worms that must have had a really hard time of it. He expected all the worms to have drowned, and that the only upside to look forward to was that the wet winter flooding would have meant that his silty, muddy but still-alive grass would not be peppered, as it usually is during the winter, with irritating worm casts. But lo, within a couple of weeks of the last inundation, the casts are back. How do worms survive against all the odds, he muses in his email? And is there anything he can do about worm casts that constantly mess up his lawn?
