Cucumbers not growing
Small cucumber fruit could be due to poor pollination. It could also be due to restricted roots if you are growing in containers, low soil fertility, or too high air temperatures.
You can try hand pollinating some female flowers, then mark (very loosley tie a soft piece of string around the stem) and watch these flowers to see if you get better results. Here is information on how to tell male and female flowers apart, and the hand pollination procedure.
Also, be careful that insecticide sprays aren’t getting on the plants. You want lots of bees and other flying insects to visit the flowers. I hope this helps,you get more cukes!
