My OH has made wooden farmed cages to grow the purple sprouting in, fine netting stops the cabbage white butterflies. I used to squash the caterpillar eggs whenever I was in the garden, then he came up with this idea.
Salad crops are always good to have, runner beans/broad beans. We grow a few early potatoes but for the space they take we don't grow main crop. Onions and shallots for pickling. Beetroot. Carrots are hit and miss, one year good crop next year not but he keeps trying (this year was good). Going to plant some peas this year for a change. Also going to try outdoor tomatoes, usually only do greenhouse ones.
Herbs in garden and I also plant up a trough and have it sheltered so keeps going most of the year. We have kept chilli plants going through the winter in the greenhouse.
We also have soft fruits strawberries, raspberries, gooseberry, blackcurrants.
