Hi Dennis. I remember reading in an earlier post that you were spacing 7 feet, and honestly, I'm still thinking about it.
My thinking right now on the spacing though is that it's going to be somewhat variable, as I know that some varieties will tend to be more upright, and others more spreading. The "Unknown Yellow" variety (figs on the left in the test mini-hedge) I am growing can grow very successfully in a smaller area, our HC is very upright in habit, and I am looking for a privacy hedge pretty quickly, so I am really thinking 5 (smaller and more upright) to up to 7 for known larger varieties. I'm also going to have to work around the stumps.
The good news though is that this isn't sky diving: If it doesn't work, you get to try again and fix things as you go and as you see how the plants are growing.
I expect that it will be somewhat fluid in that some will die and have to be replaced (or just let the neighboring figs fill in, some of the varities tend to sucker a lot and spread (these runner plants can be taken out for new trees also).
But I'm sure that 7 feet is a very good spacing in general, and for ones that I know like to spread (like the LSU Purple), I will give them more space.
But I don't really want a just row of bushes, we want more of a hedge effect. The Leyland Cypresses were there for a reason, and we want a little privacy hedge, at least in the summer months.
Keep us posted on your progress Dennis.
Best wishes.
