F1 All Female Cucumber
 

this year I am growing F1 Prima Top variety - nothing different to my usual
greenhouse set-up but I am getting a lot of male flowers as well as the
females. Also the females have not been developing into cucumbers.
Only last week have a few started to develop further.
The greenhouse is heated and the cue's are in 12 inch pots.
This is the first time I have has male flowers growing so freely on an all
female variety.
Anybody else having this prob??
