When to Trim Trees and Shrubs (Part 2 of 2)

Viburnum in BloomDeciding when to prune/trim is confusing to many people because there is no one-size-fits-all answer and even the experts can’t always agree. Yet, it is the most commonly asked question of gardeners, landscapers and arborists! Pruning of live branches is not as critical as many people think, but it is worthy of discussion.

The Best Times for Pruning: (the opposite of Part 1; Worst Times)

  • A mild, dry and seasonal day
  • When the plant is healthy and hasn’t recently been disturbed by construction, storms and/or heavy pruning
  • It depends on how much you plan to cut off;
    A Heavy Trim >50% cutbacks of shrubs, the best time is late winter, early spring
    A Medium Trim ~25% maximum amount to remove annually, early spring and summer
    A Light Trim <15% anytime of season
  • It also depends on whether or not you will miss the full flower effect;
    If you won’t miss some of the blooms, prune anytime of season
    For plants that bloom on current season growth, in late winter, early spring
    For plants that bloom on previous season growth, right after bloom
  • Lastly, Dead branches can be pruned anytime!

In general, the optimal times for ornamental tree and shrub trimming is early spring and summer and those should be the go-to times if you are unsure. Don’t let timing keep you from grabbing your pruners if a haircut is truly needed and you just can’t wait!

When to Trim Trees and Shrubs (Part 1 of 2)

wetmapleIf you are trying to figure to out the best time to prune/trim, start first with the worst times to prune (because more experts agree on these) and work backwards from there.
So, what are the worst case scenarios in pruning at the ‘wrong time’?

  • loss of flowers/fruit
  • health decline/injury
  • and/or death

One important point is that pruning at the ‘wrong’ time of year probably won’t kill your tree or shrub, but it may weaken it in the long run. Indeed many plants are trimmed at less than ideal times and yet they survive.

The Worst Times for Pruning:

  • In the rain. Many bacterial and fungal diseases are spread during cold or hot wet weather and fresh cuts make easy access.
  • During a severe drought, or flood like conditions. Energy is precious at these times and taking off branches is adding additional stress.
  • When current or upcoming temperatures are extreme. Fresh cuts are open, exposed living cell tissue that can dry out or freeze and the wood surrounding the cut can dieback.
  • When your tree or shrub is unhealthy. Wait for it to recover by giving it time and treatment (if necessary) before pruning.
  • After storm damage, root injury (like construction) or heavy pruning. Plants need time to recover from loss of branches and roots before any trimming is done.
  • Right before bloom. Does this really need explaining? Well, OK, maybe flowers and fruit aren’t your first priority.

Stay tuned for the When To Trim, Part 2 next month.

Dead Branches in your Trees

IMG_3967Dead branches are a natural phenomenon and provide habitat and food for many creatures such as birds, bats, insects and fungi. So why would you have these pruned out?

Well primarily because they are dead, they become dry and brittle and have a tendency to break off in strong winds. Especially the winds of our Nor’easters in the NorthEast. Also dead stubs and branches can be entryways for fungi and bacteria to enter live healthy wood at the attachment points and spread to other parts of the tree.This is especially a concern if the tree has an aggressive or infectious pest attacking it and/or trees nearby. Lastly, on some species, pruning out dead also will greatly enhance a tidy appearance of your trees, giving them a less ragged and messy appearance.

When weighing whether or not to spend the money to have them pruned out, some Q’s to ask yourself are;

  • Is there property or people below that could get hit by these branches? Further, if there is a walkway, how often is it used? e.g. what is the risk level?
  • What is the cost of trimming vs. the cost or repairing a fence or shed?
  • Is the branch of a large enough size to cause damage if it were to break?
  • How important is the health and appearance of this tree to you?
