Can anyone suggest what flowers can be planted amongst
brassicas, to discourage butterflies. There's also
another for the greenhouse to combat tomato pests. Also
how do these CP's work? TIA.

They work in a variety of different ways, for instance planting marigolds
or anything else with bright yellow daisy flowers will tend to attract
hoverflies which in turn will lay there eggs on your plants and the
resulting lavae eat the pests

Then planting something smelly like onions or garlic near carrots etc
disguises the smell of carrots and distracts carrot root fly from finding
your carrots

Probably the best bet for brassicas is to cover them in net or fleece to
stop the butterflies
