Would that the nematodes killed snails as well as slugs - but they don't. Since I rarely see a slug but have masses of snails, it's been a problem here in Hackney, too.
I lost all but one of my first batch of climbing bean plants to the wretched creatures but the second batch, which I grew on the window-sill and planted out surrounded by positive barricades of crushed eggshells, did better - even though most of them didn't bear until late in the autumn.
