I have four Sand Hill (neutered) olive trees. I use them to block the neighbors. Last year, I had them trimmed way back, and it put them into shock. They are still alive, most of the growth is on one or two limbs. I kept knocking off suckers as they came up. But now I thought because I just want them for cover, why not let them grow into a bush. What is your thinking on my problem? Should I let the suckers keep growing or not?
I’d let them grow as they want for a few years, so they bush up and out. Since you are not using them for their produce, you could then trim the plants later on. That way you’d have growth to deal with. (When you prune an olive tree, you always cut it right back, so if you were to do the right thing - for olive production - you’d always have gaps).
By treating the olive tree as a bush, you would have lots of green (no olives!)
