Can cucumbers be grown in greenhouse in winter?
Growing cucumbers in an unheated greenhouse allows a gardener to extend the growing season until the end of November. Even with limited temperature control, greenhouse growing benefits the cucumber plant. With the proper care, cucumber bushes can produce up to 20 pounds of fruit per plant.
How long do greenhouse cucumbers last?
Cucumbers are grown as an annual, which means that the plant does not regenerate after the growing season. Once it has lived out its life span of roughly 70 days, the plant dies and cannot be regrown.
Should I remove male flowers from cucumber plants?
