They are really easy to put together .. just don't make a complete circle with the cage part or you'll have fits lifting the inner pots in and out. For the first month of growth you'll want to train the vines to go horizontally. I bury the pots half way into the ground which makes it easier to mow and trim around - plus the fact if you need to move the plant just lift the main pot and go where ever. It's a great system for plants the climb and vine and superb for growing tomatoes.
Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so.
