I've had this olive tree for over 3 years on my (south-east-facing) balcony in Munich, Germany. It's getting a bit 'wide' for my tastes, and I'd like to prune it to thicken the growth and encourage it to grow up, not just out.
I'm concerned if I cut it back hard (i.e., closer to the trunk where there are no leaves), it won't produce any new leaves/offshoots.
- What time of year should I prune it? (It now has tiny baby olives)
- How should I prune it? (I.e., Where on which branches to best encourage growth?)
