Andersen suggests contacting your local Cooperative Extension Service to get free advice. Some have a certified arborist or horticulturist on staff. They offer their expertise for the area in which you live whether that in the country or a big city. You can find the one closest to you by clicking on Land-Grant University Website Directory and go to your state. Once you locate your state, click on it, and there usually will be a tab to Locate Your Local County Extension Office.
Their websites are robust, Andersen says, with information about trees, too. Or you can find a qualified tree care company to come do an assessment. You can ask them about the health of your trees, which ones might fall on your house in a storm and any other pending disasters, she says. Most routine pruning is done to remove infestation, weak, dead or diseased branches, and can be completed at any time during the year with little effect on the tree.
The wounds from pruning can spread diseases. Want to avoid tree fruit production and flowering? Tree injections might be the answer!
Although summer tree trimming is possible, it can be more difficult because once leaves fully cover the trees, it can be difficult to identify branches with problems. However, summer is the best season to identify which branches are weakened due to the weight of the leaves; these branches will sag compared to healthy branches.
Additionally, tree species which fall under the category of spring-flowering trees are better to trim in the summer, as after trimming takes place, the branches will form more flower buds if trimmed shortly after spring flowers have faded. There are several species of trees which benefit from summer trimming as well because they produce a lot of sap which can make trimming difficult in late winter or spring.
Species which do best for tree trimming in summer include:. Trimming these species of trees in summer helps you avoid the sticky mess you might experience with these species in other seasons. And again, if the flowering bothers you, some tree injections offer a deflowering agent that keeps them from producing fruits which can cause a mess as time goes on.
Annual treatments like this keep your tree looking great without all the cleanup later! Fall is, in general, the worst time to trim a tree.

But as you know, with each rule of thumb there are exceptions. For most species, the best time to trim trees is in the dormant season — November through March in temperate climates — because they are less susceptible to tree pests or diseases which are inactive then.
Pruning in the growing season when pests and diseases are active exposes fresh pruning wounds to potential infestation and infection. Trimming trees in spring is possible, but you have to follow some important rules. This applies to small and medium trees. When trees are rapidly growing, pruning wounds can seal and close faster, which is better for your tree. But you never want to over-prune your tree because it can stress it out as it continually tries to replenish its canopy. If you can prune your trees before they begin growing, that still counts as dormant pruning and is the ideal time to prune because of these benefits.
These types of plants develop their buds prior to spring and also grow buds on old wood. Trim these trees in the autumn. Evergreen pruning differs slightly from other trees. Watt recommends pruning all evergreens — except pine — in early spring before any new growth starts.
This means following the natural branching pattern of the tree to cut away any winter damage, as well as trimming dead foliage. This will help preserve the original shape of the tree. Aesthetically, regular shearing will give evergreens a fuller, denser look over time.
W ith the correct tools, pruning and reshaping a tree is a simple DIY project. But, when should we call in professionals? Another time to wield the shears is when small or medium trees begin to develop suckers at their base. Since suckers are closest to the root system where the tree stores its energy, they divert it from the main plant and focus it on themselves.
The arborists at Davey Tree Experts in Burlington have a rule of thumb — if you have to work from any great height, call in a professional! The structural integrity of the tree can be compromised and turn it into a danger during storms, leaving it susceptible to lost branches or even uprooting. Another reason to call in help is if the tree is showing signs of real sickness or disease that needs to be treated.
An arborist can also help if it has been many years since your tree was pruned.
