Photo Description

Top Left: Tree unbalanced. Left side producing little. Right side producing well.

Top Right: Shown from opposite side. Full limbs visible without flowering.

Bottom left: Close up of the left side of the tree. Several branches not flowering down full length.

Bottom right: Closer view of the graft and up.

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.

    These are very helpful, yes. I’d check the ‘dead’ branch with a scratch test along the length to be sure but if they fused around bark that’s a detrimental factor to consider in favor of removal. In case you’re unfamiliar, a scratch test is just taking a fingernail or sharp sterile blade and scratching away the outermost bark - if it’s brown all the way down she’s a dead branch but if she’s green there’s growth to be seen. If/when you end up removing it remove the weight past the live branch to reduce or prevent any extra bark damage.

    As for those new buds: they appear high enough in the graft that I’d leave all three. The lowest might be from below the graft but it will still help to fill in that side this season so there’s no reason to remove them now. If anything, resterilize your knife and make small, delicate incisions just above each bud to promote their growth. The small wound will cause the growth hormone (auxin) to pool at the buds, giving them a boost this season. The additional growth should help you determine whether they’re from above or below the graft, and you can make a decision about them during their next dormant period.

      What a wealth of info. Thank you!

      If/when you end up removing it remove the weight past the live branch to reduce or prevent any extra bark damage Do you mean to say that only the dead limb beyond that which fused should be removed?

      I was going to post a new question about this fusion. I was wondering if it should remain and how much, or… perhaps removing it entirely? If the latter, this would expose the live limbs flesh in a what I presume to be a negative manner. That them made me wonder if there was some sort of gum or salve to apply to allow it to heal and prevent problems like disease.

      This is really interesting. I will want to look into a bit more, but it sounds like it could really help. Thank you!

        You may be reaching a point where there’s an increased risk of pests or diseases but if the fused branch is already presenting an increased risk it’s worth it to remove and observe how the tree closes the wound.

        some sort of gum or salve to apply

        Here’s what Purdue University has to say but the big takeaway is

        There are few ways wound closure can be hastened, or at least not inhibited. First, it is essential to avoid limiting oxygen availability to the wounded tissues. Oxygen is necessary for proper recovery. For example, painting a wound with any kind of material that interferes or impedes oxygen will slow or even prevent wound closure by poor callus formation. Wound treatment with petroleum-based products is not recommended. In fact, research indicates any type of wound dressing can slow the healing proces

        I think the best course of action if the fused branch is dead or rotty is to remove it and keep a close eye on the spot where they fused, and for any other disease indicators.
