Please do ask for any more clarifying photos if you think it would help.
Questions:
-
The tree just started blooming this week. Is it too late to start pruning or should I wait until Autumn?
-
Pruning the tree is going to make it even more lopsided than it already is. Would you all recommend trimming back the healthy branches so it’s not so heavy on one side?
-
This website gives the advice below. Any thoughts otherwise?
Thank you all so much!
How to Prune a Weeping Cherry Tree
The different types of weeping cherries can grow to between eight and 40 feet tall. Proper pruning keeps these trees looking beautiful and can prevent the development and spread of diseases. Prune while the tree is dormant (no flowers or leaves on the branches) in early spring or late fall. Take the following steps once a year with bypass pruning shears or a pole pruner.
- Cut back any branches that contact the ground until they’re at least six inches off the ground.
- Remove branches that are rubbing against each other.
- Trim back branches that are closer than two inches apart.
- Remove dead branches.
- Remove stems or branches growing out of the trunk or around the base of the tree (a.k.a. suckers).
- Trim back the tips of the branches around the perimeter of the canopy until it’s a balanced, uniform shape.
- Remove branches that are growing straight up on grafted cherry trees because they will continue to grow upward instead of weeping down.
- Thin out the mangled cluster of branches that often develops near the base of the canopy of grafted trees.
- Remove diseased branches as soon as they’re discovered, regardless of the time of year. Sterilize the blade of your cutting tool in between cuts to prevent disease spread.
Probably fine to prune as long as you are conservative about how much you remove. Pruning while the tree is actively growing can increase the risk of reactionary growth caused by removing too much.
I wouldn’t try to balance the tree by removing more than necessary unless you have some reason to think it’s unstable. For a small tree like this, the weight difference probably won’t be that significant.
If you are worried about it, you could leave some lower-priority pruning cuts for next year. Pruning is a process, it doesn’t need to happen all at once unless there is an issue of health or safety.
Thank you so much for your response! Based on your light touch description, now is probably not the time to prune the dead branches from the more bare side. I agree that the tree doesn’t seem unbalanced, albeit the trunk isn’t entirely vertical and leans a bit towards the fuller side. I agree that it’s lack of density isn’t likely the cause or an issue.
The bareness of one side is curious to me. I wish I could contact the previous owner. I also wonder if the magnolia tree, offset about 40ft/12m, has a part in that. It’s about 45ft/13.75m tall itself. The magnolia is far off enough so as to not shade the weeping cherry at all, but perhaps the resource competition could be an issue?
What time of year do you recommend pruning of dead branches?
I don’t suppose you know of any magic that will coax the sparse side to start produce more?
