I have bought Gynial F1 cucumber plants. Do I have to remove the male flowers?

Question

It says Gynial is an outdoor cucumber but can I grow it in an unheated greenhouse?

Answer 1

Removal of male flowers will mean that there will be no pollen to pollinate the female flowers. In fact, since you will be doing these indoors, essentially, you will need to keep these male flowers as they drop off so that you can use a paintbrush to hand pollinate the female blooms. You will have to pollinate them by hand with a lack of insects to do that for you. I find cucumbers do fine indoors as long as you pollinate them on time.
