I grow in raised beds and have no problems w/ tomatoes in a bed next to the cukes. As long as you don't plant nearby in the same container or soil you should be perfectly fine.

I plan to plant them in a spot with a bag of composted chicken manure in Zone 8b. Any suggestions? Last year my cuke plants were glorious and were started from a packet of seeds. Unfortunately I did not get one cuke. Lots of flowers but I think they turned out to be all males.

Same problem here this year; beautiful leaves, taking over the area on my balcony....but all male flowers!!!!!!!!!!!!!!!! I know with tomatoes you have to get the temperature to drop low enough to get them to fruit, maybe same with cucumbers?

Mix in well composted manure with some good friable soil - about 1 part manure to 3 parts soil. Too much manure and the soil will have too much nitrogen. The female flowers have little cucumbers behind the flower. You need bees to pollinate the flowers. Check between 7 and 11am to see if bees are active. You can hand pollinate, read how to do it.

It is very hard to grow things during summer along the coast in Qld with all the rain and heat. Generally start planting seeds etc late Feb/Mar. Rain brings on the breeding cycle of a lot of insects etc. If plants are growing fast and too big - too much nitrogen. Yellow leaves - with lots of rain the fertiliser is leached through the soil. Also yellow leaves can be from a trace element deficiency. Use a fert that has trace elements. Here is my tips - during summer try and improve your soil with compost manures etc. Put grass clippings and leaves etc on you garden bed and dig in and turn over a couple of times during summer. Soil has to be watered to help break down the leaves etc. You should then only need a very light feritising.before planting in March. Plant cabbage broccoli etc in early May.
