vegetable varieties that benefit each other?

[lenathatch]

Are there certain vegetables that benefit from being planted next to each other, i.e to help fight plant deseases, enrich soil etc. Any experience on the best combinations?

Carrots and onions are good in the same bed. Onions deter carrot fly. Other than that I don't know - just tend to bung 'em in where there's space!

Three Sisters?

It's all a bit much for me to take in. There is a man at the allotments who always plants his radishes with his sprouts etc. But I just stick with making sure I rotate crops or put something different in a space I've just made.
I do have marigolds around the tomatoes though.

Marigolds are the answer to everything. And they look so pretty nestling in the veggie beds!

And borage - meant to be amazing.

But yes - onions and carrots are meant to be a good combo. Also poached egg plant is meant to be good too. And chives near other (non veggie) plants.

And apparently chervil deters slugs.

savoury (spring or winter) for beans

keep potatoes away from onions and sunflowers.

camomile for sick plants

plant garlic beside roses

chives under apple trees

basil and tomatoes together
