Answer: Cucumbers normally produce both male and female flowers. The heavier bearing gyonecious varieties, however, require a pollinator because they produce only female flowers themselves. (Be careful not to rogue out the poor producers -- they will be the pollinator plants.) The process for starting and growing these cucumber plants is the same as for any cucumber. When you grow them under row covers, you will still have to provide for pollination either by raising the cover periodically so the bees can access the plants, or by doing it yourself with a soft brush.
