Just wanted to find out why you should avoid planting cucumbers next to tomatoes.. I did just that before reading this. My plants are small so is it possible to move them? I just dont want to disturb their new area. Any feedback on this? Thanks so much. your website it terrific!

My cukes were planted about a foot ( 30 cm ) away from my tomatoe plants this year.and my crop from both was unreal. The tomato plants acted as a trellis for the cukes. I could not keep up with the supply....

I live on the Gold Coast, and have been growing mad hatter capsicum successfully for about three years now, and grape/cherry tomatoes about the same but not very much fruit. This year I planted continental cucumbers. The plant grew very large in about two weeks, (5 foot+), and the leaves are huge, but I have only had 4 fruits and the leaves are being eaten so badly that they look like a very thin, worn out, see through piece of material. This past month for some reason every capsicum, yellow, green and mad hatter, all produced rotten fruit, and I ripped out the plants, except the cucumber. What has caused this? I may have over fertilised.. Also all plants are producing a lot of yellow leaves, especially the tomatoes.
