Prune Evergreen Shrubs
Prune evergreen shrubs
Late spring is an excellent time to prune evergreen shrubs in the landscape. Pruning just after the emergence of the spring growth will provide a basis for helping to shape the plant while retaining the natural look.
How far back can you trim evergreen shrubs?
New growth can be sheared back or thinned close to the dead zone, but you should try not to remove any more than two thirds of new growth.
How do you prune an overgrown evergreen shrub?
One method is to prune them back over a 3-year period. Begin by removing one-third of the large, old stems at ground level in late winter/early spring (March or early April). The following year (again in March or early April), prune out one-half of the remaining old stems. Also, thin out some of the new growth.
Can you prune evergreen shrubs in the fall?
Pruning evergreen bushes is best done in late March or early April before new growth begins. Light pruning can also happen in late June or early July. Avoid pruning evergreen shrubs in the fall, since they are more susceptible to winter injury.
Is it better to cut back bushes in the fall or spring?
Winter is usually the best time. Dormant pruning is usually done in late winter, six to 10 weeks before the average last frost in your area. You can prune shrubs at any time of year if it's necessary—for example, to remove broken branches or dead or diseased wood, or to remove growth that is obstructing a walkway.
Should shrubs be trimmed in the fall?
DON'T prune during fall. No matter what type of shrub you have, fall pruning can stimulate late-season growth that may not have enough time to harden. This can weaken and damage the plant—especially if there's an early frost. Instead, wait until winter and trim bushes when the plant is in deep dormancy.

When should I not trim my bushes?
Prune these shrubs in late winter or early spring before growth begins. Do not prune deciduous shrubs in late summer. Pruning shrubs in August or early September may encourage a late flush of growth. This new growth may not harden sufficiently before the arrival of cold weather and be susceptible to winter injury.
What happens if you cut the top off an evergreen?
Large evergreen trees do not respond well to topping. The removal of the upper main stem through topping opens the tree to internal decay, disease or damaging insects; it also removes the most productive portion of the tree.
Can you cut shrubs all the way back?
This is called rejuvenation pruning, and it involves removing branches all the way down to their base. That's right – the entire shrub is cut off just above ground level or up to 6” to 12” above the soil, depending on the type of shrub.
How do you reduce the height of a shrub?
To thin a branch, you'll need to cut it back to a bud or to the main stem. In other words, don't indiscriminately cut the new growth that shoots out; cut it back to a bud or back to the main stem. If you're doing final shaping cuts (see flowering bushes section below), cutting at random heights is fine (in moderation).
Should evergreens be trimmed from the bottom?
The first cut should be from the bottom and about a third of the way through the branch. If you remove the entire branch, keep this cut a foot or so from the main trunk. The second cut should be from the top just beyond the first cut. This cut is made until the branch falls off.
Is it OK to prune shrubs in October?
October sees the start of the dormant season which is the best time to prune lots of deciduous garden trees. You can prune newly planted trees to remove any damaged growth and help balance the shape of the canopy as well as maintain a dominant main leader.
Is November too late to prune shrubs?
After “how?", the second most-asked question we get about pruning is “when?” (Or, "Can I prune this now?") The rule of thumb is to prune immediately after bloom for flowering shrubs, in late winter or early spring for non-blooming shrubs (particularly for heavy pruning), and not after mid-August for any shrubs.
What plants should not be cut back in the fall?
There is no need to cut back hardy geraniums, heucheras, hellebores, dianthus and moss phlox. Tidy them in the spring as needed.
Can you prune in the fall?
The rule on fall pruning is, generally speaking, don't prune in fall. But there are a few trimming tasks you can take on with confidence, provided you approach the job with self-control and a plan. The timing window for these pruning chores is from Thanksgiving to the New Year.
Where do you cut when pruning?
Know where to cut. ALWAYS prune back to or just above a growing point (branch or bud) or to the soil line. NEVER leave a stem or branch stub. NEVER top a tree to “rejuvenate” growth. Â This ruins the plant's natural shape and greatly increases its susceptibility to diseases, insect pests, and storm damage.
How do you cut back bushes for winter?
When pruning, first prune out dead and diseased branches, especially those caused by the winter's snow and ice. Unwanted lower branches on all evergreen shrubs and trees should also be removed in late winter. Remove overgrown and smaller branches to increase light and air at the crown of the tree.
Can you cut shrubs too short?
Over pruning a shrub or tree can actually stunt its growth or damage it. New leaves and branches can get weak, and the plant can also become prey to insects and other bugs.
What is the 1 3 rule for pruning?
The 1/3 rule involves cutting about 1/3 of wood during any pruning activity. This moderate pruning practice is a balanced approach to thinning out shrubs to stimulate new growth. The plant loses a good amount of stems, usually on the top section, allowing more light and air to enter the inside of the plant.
