I topped too many plants this year. Put 4 feet between the plants. Now I have half the plants 4 to 5 feet wide and 3 to 4.5 feet tall. The ones I did not top are prodecing less. I would have to next year have the topped rows 6 feet apart or more. Here's the photo. The one plant shown is a wartryx 3 x 4 and growing with around 30 big pods.
