I've had great success with growing toms in grow bags in the past. Very efficient, and easy to clear away once done. An old gardening pal also swore by them because they retain moisture and as toms are better under watered it meant that it didn't matter if they didn't get watered for a couple of weeks. Also my other halfs uncle enters shows with his and he swears by using the bags. He says he gets better results by keeping the roots shallow.
Ive just looked in my Companion Garden book by good old Bob Flowerdew. He says marigolds help keep whitefly out of greenhouses but won't drive them out if they are already in. It says to plant marigolds 'near' tomatoes. Says the scent hides the smell of the plant.
Also says there is research that marigolds kill nematodes And that "....exudations may help tomatoes" - no idea what exudations means!! Where's my dictionary.......
