Howdy, Pod...
Actually, I was thinking since they were much smaller plants than my other indeterminates that I could plant them closer. However, their huge amount of foliage really surprised me. I really think their foliage is what added to their wonderful flavor; I'm one of those who believe the more leaves the better the photosynthesis thereby giving a better taste due to sugar/starch processing.
I think next year I'll set these out almost 3 ft apart, not only for better visibility of the fruit but also for good air circulation around each plant.
Hope this helps.
