Hiya Jonny.
I know you've posted twice - I thought you were trolling ... sorry )

Here is a site which is a good start.

Also:-
Basil improves the flavour of many garden vegetables, specifically
tomatoes
and lettuce, and repels flies and mosquitoes

Borage near strawberries and tomatoes attracts bees, which help to
improve crop yield by pollinating plants

Comfrey Tap roots bring minerals to the surface of the soil.

Dill and fennel attract hoverflies, which then eat aphids. Dill grows
well
next to lettuce and cucumbers

Garlic and chives keep away aphids and black spot and planted round
fruit trees/ bushes discourage insects from climbing the trunk. Garlic
also improves the growth and health of raspberry bushes and can enhance
the production of oils in herbs Chives enhance the flavour and growth
of tomatoes, carrots, apples, berries and grapes.

Marjoram and oregano are helpful to all vegetables

Rosemary benefits beans and carrots.

Sage amongst the brassica family, particularly cabbages repels cabbage
white butterfly. Sage also benefits carrots, peas, beans but does not
like cucumbers. Sage provides cover for frogs and toads that eat snails
and slugs.

Summer savoury deters black fly.

Tagetes (like Martin mentioned) (African & French marigolds) Excellent
on your plot. Deters aphids and whitefly through scent and by
attracting hoverflies. Mexican marigolds (Tagetes Minuta), stops ground
elder All marigold roots secrete chemicals, which help stop bindweed.
The roots also stop eelworm from recognising their host plants, which
include potatoes.

Valerian amongst your veg stimulates earthworms, which helps to boost
plant growth.

Wormwood, hyssop and rue on your plot borders act as insect deterrents.


Also you should check out how to make organic fertilisers, beside OM,
out of plants. And there's many vegs that do not like each others.
Like, garlic is bad with cabbages, peas and beans. Carrots don't like
to be next to beetroot. Strawberries don't like to be next to cabbages.
Beans don't like to be next to garlic, oignons, shallots. Salades don't
like to be next to celery and parsley and tomatoes don't like to be
next to cucumbers, gurkins, potatoes, peas and beans. Phew ... Good
luck!
