My brussel sprouts have grown the leaves etc and to a reasonable height but no sign of "fruit" yet. Instead the heart of the flowering leaves is covered in soft substance, bit like insect poop (?!). Have they got some kind of disease or is this normal? We've had a lot of rain so not sure if this is the problem?

Any root crops would be fine, carrots, turnips, beetroot, Parsnips if you like them. Although the soil will be fully depleted afterwards. Grow a legume then or add compost before planting similar fruiting crops again. Or grow legumes now, Broad Beans at home are going great. after harvest dig-in, wait at least 2-3 weeks & plant up your fruiting summer crops in October.
