In my experience, the tomatoes grow well but the cucumbers struggle .

Tomatoes have a deep and wide root zone and would probably pinch most of the water and nutrients in the soil. Tomatoes need a lot of water and fert, cues far less. That is why I never recommend planting things too close to each other, give them the required area they need.

I have just read on several websites that tomatoes and cucumbers are compatible. Don't grow near potatoes. I recently had tomatoes in one bed and cues in the next bed, beds 1.2m apart, beds 4.8m L x 2.5m W. Cues need space to spread out so don't plant close to other crops. Also consider if the tall plants will shade out the lower growing crop.

Tomatoes and cucumbers can be grown together successfully, and there are actually some benefits to planting them together. Both plants have similar growing needs when it comes to sunlight, soil conditions, and watering. And if space is at a premium, interplanting the two will allow you to get more out of your garden.19/07/2022. Always confused by planting guides comments would be interesting.I grow toms in a greenhouse start them feb march so they are up and flowering before the dead of winter and grow cucumbers also but as far away as possible it's 2.5 by 4 meters so it's not very far.S I asked mr google the question here is what he gave me. https://www.allaboutgardening.com/tomatoes-and-cucumbers/ P.S.any tips on soil sterilisation of greenhouse soil My father used to dig out the entire contents every year to replant but that was a bit extreme I have used boiling water, peroxide with some success any other tips (you can't buy basamid anymore)

Hi, I planted 2 Lebanese cucumbers last year and again this year. Both were/are healthy plants. Issue is..there are many female flowers (hundreds) and they just wither and die. Not a single male flower both seasons. Should I be planting a different variety of cucumber nearby to help with male flowers and pollination? Help!

The yellow leaves might be due to too much fertilizer. Try just using one type. They should grow if you are giving them enough water and protecting from very cold nights. The female flowers have a tiny, cucumber shape just behind the flower.
