I have already missed the time to prune my 1 year old dwarf purple leaf plum tree. Should I wait until next early spring before it buds or go ahead and trim it now? It has no more buds and seems quite top heavy. The tree was planted last year (in late spring). It budded for the first time in late Feb. or early March. All buds and flowers are gone now. There are shoots coming out low on the trunk and the growth is thick and unruly. The tree looks top heavy and leans a bit in strong winds. I'm afraid it might break.
You can prune at any time in the season.
Here are a few articles which give very good pruning and trimming information.
My purple leaf flowering plum is losing the smaller leaves. What causes this? The small leaves (i.e. new growth) are falling off my flowering purple leaf plum. I spray Sevin for pests but the younger leaves keep falling off. Why?

I would like to give it a hard pruning..do you think it would be harmful?
I believe that it will benefit from this. Now would be the time to do so as well! This article will help: https://www.gardeningknowhow.com/ornamental/trees/sand-cherry/pruning-plum-leaf-sand-cherry.htm
Our plum tree is oozing small amounts of gelatinous material from its bark. There are two areas at the base of the tree roots and one at a fork of an upper branch. Some is clear in color the other brown and both are very sticky. I have cleaned them up and it stopped for a time them returned. I have made up Neem oil and tried that. Other than this the tree looks very healthy and sending out new branches. Thank you.

An old inherited purple leaf plum has been sending out suckers in the surrounding grass for a couple years. I usually mow them or, if they are close to the tree or other plants, cut them with secateurs. Now, though, the suckers have multiplied. There are dozens ranging in distance from less than a foot up to 70 feet away, and because some are hidden between shrubs etc it's difficult to catch each one before they get woody. I used a systemic brushwood killer dripped (not sprayed) on the cut stumps of invasive Privet and Ariala Spinosa (Devil's Walking Stick); 2 two doses over about 6 months eradicated them. I'm confident I could use the same method on these suckers without affecting adjacent plants, but I wondered if it would work satisfactorily. I would like to cut down or severely cut back the parent plum which has become too large for a driveway and overhead power lines, but suspect it will encourage more suckers. Aside from cutting or pulling up the suckers, what options do I have?
Id say that your best option is to kill that tree with any method that you can. It seems to be in distress. With this being said, it will do anything to stay alive. It is going to take some diligence to rid your yard of this. I'd say to continue with your plan, and keep on top of it. They will continue to grow back at every chance.
