Cucumbers can be staked though it is not a requirement when you are growing them. The first thing you will want to do is to plant the cucumbers in appropriately sized bags or pots in the event that you are growing them inside a greenhouse. Put the vertical stake between each of the bags you have and put wires going horizontally along the length of the roof.
You will want to train your cucumbers to grow up the length of the stake and along the wire which you have set up. As the cucumbers being to grow they will start to hang. In order to help your cucumbers grow you will need to remember to pinch out all of the tendrils and flowers.
