What season does cucumbers grow?

It is now late July and you will be seeing cucumbers in the stores.

Does that answer your question ?

In Ontario they grow cucumbers year round in green houses ( with no dirt . . . all chemical liquid crap and the cucumbers taste like it ! In my opinion . . . ).

Plant cucumbers in the spring ( I plant the 3rd week of May in Ontario, when I am in Colorado, I plant the 1st week in June. )
