Now is the time to dust off your pruners and start those late winter pruning chores. Late winter is the time many plants in the landscape are pruned before new growth begins in the spring. February is usually the best month to complete these pruning chores.
When it comes to what you can prune in February, here is a list of plants: blueberries, crape myrtles, fruit trees, muscadine grapes, ornamental grasses, roses and summer-flowering shrubs. Summer-flowering shrubs would include ones like abelia, butterfly bush, hibiscus, lantana, ligustrum, nandina, photinia and wax myrtles.
There is one group of plants that you would not want to prune now. Do not prune any spring-flowering shrubs and trees. Since they have already set this year’s flower buds, pruning now would remove their spring show of blooms. Spring-flowering shrubs and trees not to prune now would include azalea, dogwood, forsythia, magnolia, quince and viburnum. Instead, prune these spring-blooming plants after they finish flowering in the spring but prune them before late July before they start setting next year’s flower buds.
Pruning techniques for these plants can vary some, so you have to remember what purpose the plant serves in order to know how to prune it. For landscape plants like crape myrtles, ornamental grasses, roses and summer-flowering shrubs their purpose, is to provide flowers and beauty to the landscape. So when pruning, you want to maintain an attractive shape and to have a nice display of flowers.
For blueberries, fruit trees and grapevines, the pruning techniques differ some in that you are training the plant to result in good fruit production. You want a plant that has a strong main trunk or base in order to support the plant and fruit. Branches should be spaced out to allow the plant to intercept as much sunlight as possible. Full sunlight is needed for good fruit production.
As when pruning any plant, you should always first start with removing the three D’s: dead, dying and diseased branches. Next eliminate any crossing branches, even if the branches are not yet touching each other. Crossing branches can eventually touch each other, which will allow for the branches to rub and open wounds that can allow access for disease and insects into the tree. Remove branches that are growing toward the center of the tree canopy or growing downward, instead of upward and outward from the tree’s center.
When pruning, there are a few pruning tools which all home gardeners should have. A pair of hand pruners is used for small branches 1 inch or less in diameter. There are two types of hand pruners. The by-pass hand pruners allow you to make very close cuts and would be used for a majority of hand pruning cuts. The anvil-style hand pruners are used in a few cases where one would need to cut succulent or tender growth. A second pruning tool needed would be a pair of loppers with the ability to cut 1- to 2-inch branches. Lastly, a pruning saw or bow saw can be used for branches larger than 2 inches in diameter.
Pruning can be a big chore in late winter, and often gardeners have questions about when and how to prune various plants. Wayne County Cooperative Extension will be having a “Pruning in the Garden” workshop on Wednesday from 10 a.m. to 1 p.m. The workshop will cover everything pruning including pruning trees and shrubs in the landscape and pruning grapes, blueberries and tree fruits. Workshop registration fee is $5. Pre-registration is not required. This workshop is part of our monthly gardening series. Call the Wayne County Extension office at 919-731-1520 to receive a full schedule of monthly workshops or for more information.
