I planted out 20 mixed brassicas last weekend and only 5 remain now. Alliums and Peas are untouched.
I’ve applied some nematodes, http://www.amazon.co.uk/Nemasys-Grow-Your-small-pack/dp/B004MLW9OI/ref=sr_1_1?s=outdoors&ie=UTF8&qid=1397208251&sr=1-1&keywords=grow+your+own+nematodes, reasonable price. Fingers crossed now.
