Hello, I am interested in planting 5,6, or much more fig trees this fall. It really depends on how close I can plant them to each other while still keeping them healthy and productive. I have seen three different trees planted about two feet apart, and they ended up looking like one tree with three different trunks. Is this considered an acceptable practice? That is... while I'm sure yield suffers a bit, is there any downside to this? Any dwarfing? What sort of spacing has worked best for you?
I have looked this up online, and while I have read everything from 30' on center to 18", I am really looking for success stories with close spacing.
Thanks
edit: apologies if this is a commonly asked question.
