Some homeowners new to the area are overwhelmed with where to start on a landscape that has been ‘let go’ for too many seasons. First-time homeowners just don’t have enough experience yet, so are overwhelmed by conflicting advice given by the talking heads on ‘YouTube’.
On the Go Answer
- Evergreen trees rarely need pruning
- Prune Summer/Fall blooming plants from January through March.
- Prune Spring blooming plants just after blooming from late Spring to early Summer
- Roses grow at higher elevations prefer pruning in March
- Plants will usually grow out of any mistakes you may make
- never remove more than 1/3 of a shrub or trees woody growth in one season
There is probably nothing that puts fear and trepidation into a gardener’s soul more than that first cut into a tree and/or shrub. Learning to prune can be intimidating for fear of turning a plant into an ugly mess, a contorted figure in the front yard, or even worse . . . killing it outright.
It would be nice if we could only plant trees and shrubs that need no pruning at all, such as evergreens. The reality is, ornamental trees and shrubs need annual maintenance to keep them renewed and looking their best.
You may have heard that pruning trees and shrubs that bloom in summer or autumn are best pruned in winter. Also, that early spring bloomers should be pruned after they have finished blooming in spring. Sometimes, however, these rules of thumb need to be ignored because of damage, neglect, a backyard construction project, or unexpected demands on your time. Don’t worry; your trees and shrubs will be able to handle any untimely pruning. Just don’t try to make up for years of neglect in one season.
PRUNING ADVICE, MYTHS, AND WORD OF CAUTION
#1 Pruning trees and shrubs at the wrong time kills them.
It’s very difficult to kill a plant simply by pruning. It may not flower for a season, but eventually, it will resume its normal cycle. There are optimum times for pruning different plants, but it has more to do with a plant’s dormancy, bleeding sap when it is actively growing, or when it sets the best flower buds. While there are optimal times to prune woody plants, if you have to prune for eased access or to remove damaged branches, you can do so at any time of the year. It will not kill the plant. Period! Enough said!
#2 Prune severely and you won’t have to prune again in summer.
It can be tempting to hack back over-grown shrubs in spring because it’s so much easier to heavily prune when a plant’s branch structure isn’t hidden behind its leaves. Unfortunately, hard pruning often stimulates new growth and lots of it! Since much of this growth will be thin, weak wood, you will have to do some thinning or it will die off on its own and cause a whole new set of problems. Severe pruning can also lead to suckers, which will require even more pruning during the following season.
It’s better to do a little maintenance pruning each year. A good rule of thumb is to never remove more than 1/3 of a shrub’s or tree’s woody growth. This retains the plant’s desired shape created from the old branches, allowing new wood to fill in the basic structure. This technique keeps your plants well-shaped, of manageable sizes, and constantly renewing themselves.
#3 Prune an ailing tree or shrub to rejuvenate it.
It’s fine to prune out branches that obviously are infected, broken or infested; but severely pruning an ailing tree puts more unwanted stress on the plant. It only forces the plant to put more energy into regrowth, and this new growth is even more susceptible to problems. Instead, try to fix whatever is making the tree sick, whether it’s a pest, a disease, gophers, or a cultural problem. Once the tree or shrub has regained vigor, you can resume maintenance pruning.
