I have a Jerusalem Cherry bush/tree and it is getting very straggly looking. I don't want to hurt it, but it needs trimming! The branches are long and spindly.
The dormant season (winter) is the best time for giving it a trim. If this is an indoor plant, the leggy growth is likely an indicator that it is not getting quite enough light. After you give it a trim, try to move it to a location where it will get a little more light.
What will correct this problem?
I suspect it needs some fertilizing, or that it's a soil problem. Another possibility is insect damage. Check the underside of the leaves for sucking insects like aphids, mealybugs or scale.
