Pruning Shrubs And Trees In Winter

You may not think of winter as the time to head outside and start pruning your trees and shrubs.  The fact is late winter is the perfect time to start thinking about gardening chores, like pruning.   Now trees and shrubs are dormant, many woody plants drop their leaves in fall and are not actively growing.  Rejuvenate trees and shrubs by pruning to remove dead, diseased wood and crisscrossed branches. This benefits the plants structure and appearance keeping them looking healthy.

Here are a few trees and shrubs to prune now:

Ornamental Pear

Locust

Plums

Crabapples

Fruit trees. Prune fruit bearing in late February and early March. Remove any dead wood or branches that have crossed or growing straight towards the center of the tree.  Apple, pear and cherry trees should have an open canopy.

Juniper

Spruce

Cypress

Shrubs:

Barberries

Boxwood

Camellias, after blooming

Crepe Myrtle

Rose Of Sharon

Holly, prune early winter

Yew

Roses, like Hybrid tea and floribunda should be pruned in early spring, just before plant breaks dormancy. Shrub roses and Knockout roses can benefit from this as well.

Hydrangea paniculata and arborescens, bloom off of new wood.  Hydrangea macrophylla blooms off the previous years growth as well as new wood growth.

Pruning tips:

  1. Use sharp shears that are cleaned and sanitized to avoid spreading any disease.
  2. Remove diseased wood immediately.
  3. Make cuts at an angle and close to the collar of the tree.  This will keep insects out that can carry disease and harm the tree.
  4. Remove crossing branches.  Cut off the smaller branch
  5. Remove thin and spindly looking branches.  This helps to thin out the tree or shrub opening it up for more light and wind to pass through.
  6. Remove suckers growing from the trunk of tree.
  7. Cut shoots growing straight up towards the center of the tree off of bark or branches, ‘water sprouts.’
  8. Avoid pruning in fall.  Plants are still growing in the fall.  Pruning stimulates  growth in plants who are otherwise winding down their growing season and preparing for dormancy.   Freezing temps can injure plants pushing new growth.

Prune spring flowering shrubs like azaleas, lilacs, rhododendron, and viburnum are pruned when done blooming.
