3Pruning
- Some plants are pruned routinely to maintain a
desired size and shape. - Pruning will promote new, healthy growth,
flowering or fruit. - Pruning will reduce the size of an overgrown
plant. - Plants damaged by insects, disease or
environmental conditions need pruning to remove
these damaged parts. - Pruning is the most least understood technique
and frequently done wrong.
4Pruning Time
As a general rule of thumb
Plants that flower before June 1 (azaleas,
dogwoods and forsynthia) prune after the flowers
have dropped.
Plants that bloom after June 1 (crepe myrtles,
hibiscus and abelia) prune prior to spring growth.
Plants not grown for flowers can be pruned
lightly anytime of the year with heavy pruning
saved for winter.
5Pruning Technique
- Remove branches that compete with the central
leader - Remove branches that grow inward or cross with
other branches. - Remove upright growth or water sprouts.
- Remove low growing branches that interfere with
vision or maintenance. - Remove suckers originating from below-ground
growth.
6Pruning Shrubs
A properly pruned shrub should look natural and
should not look as if it as been pruned.
- Pruning cuts should not be visible.
- Pruning cuts should be made inside the plant.
- Remove all dead or damaged material first.
- Remove crossing branches.
- Remove older material on plants too dense.
- Head back excessively long branches to a bud or
lateral branch 6-12 inches below the desired
height. - Do not use hedge shears. Cut each branch
separately to differing lengths.

14Pruning Technique
Heading vs. Thinning
Heading back or shearing is the indiscriminate
cutting of the ends of vigorous of plants. This
will produce a dense growth on the outside of the
plant and may cause a bare interior due to loss
of light.
Thinning, cutting selected branches back to a
main branch, encourages new growth from the
inside of the plant keeping it full. Thinning
will also help to reduce size and provides for a
fuller, more attractive plant.
15Renewal Pruning
Overgrown plants, or those severely damaged from
outside conditions, may need severe pruning.
- Renewal pruning is the cutting of a plant to
within 6-12 inches of the ground. - Best time for renewal pruning is midwinter.
- Renewal pruning will produce abundant growth by
midsummer. - As new shoots grow, prune them at a directional
bud to encourage branching. - Not all plants will respond favorably to renewal
pruning. - An alternative to renewal is a stepped pruning.
16Pruning Technique
- To remove heavy branches without damaging the
tree, a three-cut sequence is recommended. - First, cut one-fourth to one-half way through
the lower side of the limb. - Make a second cut on the top of the limb a few
inches away from the first. - Remove the remaining stub by cutting back to the
branch collar.
17Pruning Trees
Once the main framework of a tree is established,
annual maintenance pruning is required.
- Prune limbs growing at narrow angles to the main
trunk, less than 45 degrees. - Remove branches that grow inward and threaten to
rub. - Remove branches that may inhibit routine
management practices. - Prune damaged limbs.
- Remove vigorous suckers or water sprouts.
- Remove branches that compete with the main trunk
for dominance.
18Pruning Vines Ground Covers
Pruning vines and ground covers will depend on
plant vigor and will vary from year to year.
- Flowering vines need to be pruned the same time
as flowering ornamentals. - Prune to thin the canopy.
- Prune them to keep growth in bounds.
- Prune to rejuvenate their growth after winter
damage, or insect and disease problems. - Prune to encourage air movement within the
plant. - Prune to remove old growth on ground covers such
as liriope and mondograss.
19Pruning Training Hedges
Hedges that are used as privacy screens should be
pruned properly early in its life to encourage a
compact growth.
- Head back newly planted hedge shrubs to 12
inches form the ground. - Prune new growth tips to encourage branching.
- To produce a dense shrub, continually prune to
encourage new branching. - Informal hedges are pruned using selective
pruning and requires less maintenance. - Formal hedges should be sheared and will require
more maintenance. - Always prune so the base is wider than the top.
20Pruning Roses
Prune roses when the buds start to swell in the
spring.
Remove weak, diseased or spindly wood and leave
3-5 of the most vigorous canes.
Prune climbers after the first flush of growth
removing old and diseases canes.
Do not prune floribundas as heavily as hybrid
teas.
