There are many reasons to prune your trees, but before you pull your shears out of the shed, take a look at your calendar. There is, in fact, an ideal time to start giving your trees a trim. It all depends on the time of year, the type of tree, and your overall goals. We’ll guide you on the best time to trim trees to take the guesswork out of yard work.

What Is the Difference Between Tree Pruning and Tree Trimming?

Tree pruning and tree trimming are often used interchangeably, especially because they’re two of the most common services offered by local tree services, and both involve removing branches. However, they both serve slightly different purposes. 

Tree Pruning

Tree pruning is about tree health. During this process, you’ll remove parts of the plant that are detrimental to growth—like diseased or dead branches or overly thick branches that block light to the rest of the tree. This process helps promote stronger, healthier growth, while also shaping the plant. Basically, if your plant isn’t focusing on dragging literal dead weight, it can use its resources to push out new, lusher foliage. 

Pruning is typically done every one to five years, though it's a good idea to—literally—nip dead or diseased foliage in the bud as you notice it. For most homeowners, tree pruning costs $175 to $2,650. The larger the tree, the more it costs.

Tree Trimming

Tree trimming is more about aesthetics. During this process, you’ll remove branches to help your tree maintain its size and shape (for example, artfully trimming a boxwood into a round topiary or removing a branch that’s growing dangerously close to a power line). Tree trimming is meant to remove healthy branches, but when it’s done right, it also helps the remaining foliage grow thicker and faster.

For most homeowners, tree trimming costs somewhere between $75 and $1,800. You generally won’t trim trees every year, but rather every few years as they start to grow out of shape.

Best Time to Trim Trees

Wondering when to trim a tree? Look no further than the cold weather. The best time to trim is almost always the winter—though there are a few exceptions. For most of the United States, trees are dormant between November and March. Cutting a dormant tree isn’t just easier (there’s no foliage to get in the way). It’s also healthier for the tree.

Trimming leaves an open wound which makes your tree vulnerable to insect infestation and disease. During the winter, there’s less disease transmission and fewer insects. It also happens to be the same time your tree takes its annual nap. Since it varies from tree to tree, call a tree trimming service near you to create the right plan for your yard. 

Best Time to Prune Trees

You should lop off dead or dying foliage as you notice it cropping up, but the best time to prune a tree is typically when it’s dormant during winter or late spring. Most of the time, you’ll want to start snipping just a few weeks before your tree pops out of dormancy. Too early, and you’ll hurt the tree’s winter hardiness; too late, and you’ll cut off some of the blooms that would’ve otherwise grown.

Of course, this rule doesn’t apply to every tree. You should wait to prune certain flowering trees until after they bloom. Even if it’s not the ideal time, you may want to prune trees in the summer and early fall if they’re prone to bleeding sap. Remember that this may leave them vulnerable to insects and pathogens, but healthy mature trees generally bounce back fine.

When to Prune Trees by Tree Type

Though late winter or early spring is generally the best time to prune trees, that isn’t true for every towering tree. The sweet spot is typically when they’re still dormant, but there are still a few weeks before blooms appear. 

Since different types of trees may have different ideal times, here’s a look at common types of trees and when it’s best to give them a snip.

Tree TypeTime of Year
Apple treesLate winter or early spring
Birch treesLate summer or early autumn
Boxwood treesLate winter or early spring
Cedar treesLate winter or early spring
Fir treesLate winter or early spring
Maple treesLate winter or early spring
Oak treesLate fall or winter
Pine treesLate spring or early summer
Spruce treesLate winter or early spring
Willow treesLate winter or early spring

Flowering Trees

You should prune flowering trees—like dogwood, magnolia, or crape myrtles—based on when and how they bloom. Some trees produce flowers on new wood (the growth you’ll get during the upcoming growing season). Other trees produce flowers on old wood (the growth you got during last year’s growing season). As a rule:

  • If your plant grows buds on new wood, prune it in late winter or early spring right before the growing season begins.

  • If your plant grows buds on old wood, prune it in late spring or early summer after it’s flowered.

If you cut old wood too early, you may accidentally remove next year’s blooms. To avoid that, make sure you cut them right after this season’s flowers fade.  

Deciduous Trees

Deciduous trees—like oak or willow—shed their leaves before going dormant, and dormancy is typically the best time to prune them. Generally, you’ll want to wait until late fall or winter because the branches are easier to manage without their foliage and insects and diseases are less prevalent. 

If you want to prevent bleeding, don’t wait until late winter. Some trees leak sap—or “bleed”—when leaving dormancy if they’ve recently been pruned. This process isn’t harmful, but many homeowners find it unsightly. Trees like birch are particularly susceptible, so you may want to prune it during a different season, like late summer or early autumn. 

Evergreen Trees

Evergreen trees—like spruce and fir—don’t go dormant like deciduous trees, but their growth may slow down during the winter. For this reason, that’s generally the best time to prune. Prune your evergreens in late winter or early spring before growth picks back up. The exception is pine trees, which you should prune in late spring or early summer. 

Sapling Trees 

Young trees—or saplings—need time to establish themselves before you prune them. Once you’ve transplanted the tree into the ground, wait at least a year before you start cutting branches. It’s particularly important that you don’t remove the lower branches, since these protect the trunk. You can start pruning them as your tree begins to grow.

Mature Trees

Mature trees are more resilient than younger trees. In other words, they’ll give you a little leeway. Generally, you’ll want to prune a mature tree sometime between late fall through early spring when it’s dormant. The best time depends on the species. 

Some species are more susceptible to disease, so don’t prune them during the active transmission period. For example, you should prune your oak tree in late fall or winter to prevent oak wilt. Since pruning can stress even a mature tree, prune strategically. Remove diseased branches as they appear and avoid pruning immediately after spring growth.

Fruit Trees

The best time to prune fruit trees is in late winter or early spring, right before they start growing new leaves. You can also prune water sprouts and diseased or dead branches in late summer, but do this sparingly since it can stress the tree. Avoid early winter altogether since this could impact the plant’s cold hardiness.

DIY Tree Trimming vs. Hiring a Pro

If you know about trees and gardening, there’s no problem pruning your trees on your own. It’s generally pretty straightforward for a small tree, provided you use the right tools and the proper technique. You’ll need pruning shears for branches less than 3/4 of an inch in diameter, loppers for branches up to 1.5 inches in diameter, and a handsaw for anything else.

That said, not all trees are so small. Sometimes, you’ll need a ladder, and other times, you’ll need special equipment like chainsaws and climbing equipment. Branches can be enormous and extremely heavy (think: a fully mature oak tree). It can be difficult—and even dangerous—to manage these types of trees alone. In this case, we’d strongly encourage you to hire a tree cutting service near you. A professional will:

  • Know the best time to prune each specific tree

  • Know which branches to remove for optimal growth

  • Safely remove dangerous branches

  • Know how to effectively trim and treat diseased trees

Having a pro prune or trim your tree generally costs between $75 and $1,800 per tree. However, if it is part of public property and encroaching on your property, the city may trim the tree for free.

Frequently Asked Questions

Trees that flower in the spring—like dogwood, cherry, magnolia, and pear—should not be pruned during the winter. These spring-flowering plants grow buds on old growth, so you’ll actually remove what would’ve been gorgeous flowering foliage. Instead, wait to prune until right after they bloom, when the flowers fade.
