Cucumbers love water but don't like to have their roots soaking in it. I've never grown cucumbers in a pot but I would for sure get a pot much larger than what you have to allow root growth. Cucumbers are a vine that is usually trained to grow vertically. A small trellis or wire support will allow them to grow up with a little help from you. The tendrils are a part of the plant that grow and spiral around whatever is near to help it support itself. Do not tie the vine so tight as it appears in your photo. The plant will get larger as it grows. Cloth strips or special clips work best for support without girding the vine. There are no male or female plants. There are male and female flowers that grow on the plant. The male flowers come first to attract pollinators. The flower will be attached to the plant by a thin stem. The female flowers will have a miniature cucumber at its base which if pollinated will become a cucumber. A cucumber plant with growing cucumbers will be quite heavy so plan accordingly.
