How to Keep Them Standing Tall

If you are harvesting a bush variety of cucumber in the gallon bucket, you are free from the additional tension of providing support, as this type of cucumber doesn’t need backup. 

However, the vining variety will require support as the vines need support to grow vertically without entangling or touching the ground. Besides, when you add support, it is more comfortable to prune and preserve the vines and harvest the cucumbers.
