The appearance of a properly pruned plant is like a good hair cut: hardly noticeable at first glance. Presented by Dr. Teri Hamlin Georgia Department of Education Landscape Pruning Trees
Pruning Pruning at Planting: –If quality plant stock, pruning is not necessary Do not prune to compensate for root loss –latest research show pruning does not help overcome transplant shock
Why Prune Removal of dead, broken, diseased, or insect-infested branches Maintain desired shape & size (make it look natural) Promote healthy vigorous growth Promote flowering & fruiting Allow air and light to enter the interior of the plant.
Pruning Tools Sharp & Sterile
Pruning Tools Hand Shears: branches up to ½” in diameter Lopping Shears: branches ½ to 1 ½” in diameter Pruning Saw: branches larger than 1 ½” in diamter Chain Saw: branches larger than 3” Pole Pruner: long-handled pruner to reach into canopy w/o a ladder. (power pole pruner) Hedge Shears: hedges and other shrubs up to ½” in diameter Grass shears: 2 blades designed to cut grass around edges of walks or flower beds.
Making the Cut Directional Pruning- cuts should be about ¼ in above bud or beyond branch collar
Making the Cut
Pruning Technique Heading –Removes a part of a shoot Thinning Removes the entire shoot or limb
Pruning Technique Thinning Selectively cutting oldest branches to ground opens center and promotes new growth
Pruning Technique Heading Use for small leaf hedges Creates dense, tight foliage
Rejuvenating/Renewal Restore overgrown shrubs Cut all branches 4-8” above ground If there are any diseased or dead plants you should remove them first.
Root Pruning Don’t prune completely flush with the main trunk
Crown Thinning No more than one-fourth of the living branches should be removed at one time
Crown Raising Remove branch from bottom to provide clearance After pruning the ratio of living crown to total tree height should be at least two-thirds
Crown Reduction Ratio of live crown to total tree height should be at least two-thirds Never cut main branches of tree back to stubs (Topping Trees)
Pruning Young Tree A. Remove suckers B. Low Growing Branches infer w/maintenance practices C. Upright growing shoots or waterspouts D. Inward growing branches E. Branches that compete with a central leader
Large Limbs A. Make partial cut from underneath B. Make a second cut from above several inches out –allows the limb to fall C. Complete job with final cut just outside the branch collar
Pruning Limbs An Improper Cut made through the branch collar will take 3x longer to heal
Pruning Time General Rule Trees & Plants that flower before May –Prune after bloom Dogwood, Redbud, Saucer Magnolia, Flowering Cherry Azalea, Forsythia, Rhododendron, Clematis, Climbing roses Trees & Plants that flower after May –Prune prior to spring growth Chaste Tree, Crape Myrtle, Sourwood Camellia, Nandina, Sweetshrub, Abelia, Floribunda roses
North Georgia Pruning Time January - March Broadleaf evergreen Needleaf evergreen Renewal Pruning Large Tree Limbs
Pruning Paint Correct Tools Correct Time Correct Technique “Placebo” - making the user feel good Research shows that paint or wound dressings do not stop decay nor cause the wound to close faster Successful Pruning
What To Prune? On your Pruning Worksheet put a line through the parts of the tree or shrub that you feel should be pruned and tell why. Mark in pencil so you can make corrections if needed.
Plant #1: Create a central leader on this young plant.
