Trimming Trees in Summer? Absolutely!

While it’s widely understood that tree pruning is beneficial during the winter months when trees are dormant, there’s a lesser-known fact: you can indeed perform summer pruning for (certain) trees as well.

Benefits of Trimming Trees During Summer

Consider summer tree trimming as the concluding phase in your annual tree care routine. This practice occurs after the structural pruning of winter, the growth stimulated by spring’s fertilization and mulching, and prior to the autumnal splendor of colorful displays and leaf shedding.

Distinguishing itself from winter pruning, summer tree pruning serves several distinct purposes:

Enhancing Sunlight Penetration: Opening up a tree’s crown during summer allows more sunlight to filter through its foliage.

Refining Shape with Sensitivity: While not altering the tree’s overall structure, summer pruning refines its shape.

Managing Spring Growth: The removal of excessive spring growth that has rendered the tree overly large or unbalanced.

Eliminating Damaged or Diseased Branches: Identifying and removing damaged or diseased branches contributes to the tree’s overall health.

Maintaining Safe Clearances: Preventing tree canopies from encroaching on buildings and utility lines safeguards infrastructure.

Enhancing a Tree’s Crown

Summer presents an opportune time to selectively remove lateral or side branches from trees. By eliminating certain lateral branches, you enhance the flow of sunlight and air into the interior sections of the tree.

This heightened circulation of air and sunlight contributes to the mitigation of fungal diseases and the enhancement of fruit ripening.

Crafting a Tree’s Crown

During the summer season, you have the chance to engage in pruning that enhances both the form of your tree and your visual perspectives. When the branches of a tree are adorned with leaves, the overall shape and size of the tree become apparent.

This visibility simplifies the process of pinpointing the specific branches to be pruned or refined. The primary objective is to judiciously remove just enough branches to attain the desired shape or improve your sightlines. It’s important to emphasize that this practice is NOT about tree topping or significant size reduction.

Note: It’s generally advisable to carry out substantial structural pruning during the winter season. Consider summer pruning as the final embellishment to your tree care efforts.

Addressing Problematic Branches

During the summer, engaging in pruning can contribute to the vitality and well-being of your trees by removing branches that exhibit the following issues:

Dead or Dormant Branches: Those that have not come out of dormancy or have succumbed to death.

Disease Development: Branches affected by diseases like fire blight.

Excessive Growth: Branches that have grown overly large or have become unbalanced.

Obstructive Growth: Those hindering passage along walkways, driveways, patios, etc.

Branch Interference: Branches that have crossed one another, grown inward, or are causing bark abrasion.

Damage and Hazards: Broken, cracked, split, hanging, or otherwise damaged branches.

Pro Tip: Before embarking on summer pruning, it’s advisable to assess the prevailing weather conditions and adhere to best practices to ensure the well-being of your trees, preventing any undue stress or harm.

Safety and Canopy Clearance

Maintaining a safe distance between trees and buildings or utility lines is paramount. Summer proves advantageous for pruning aimed at clearance since trees are fully adorned with leaves. This visibility grants a clear perspective of your tree’s crown, aiding in the precise removal of necessary portions for safe spacing.

While the shade offered by trees during summer is appreciated, a touch of pruning can play a pivotal role in averting damage during summer storms and preventing utility disruptions.

By maintaining well-shaped and balanced tree crowns and ensuring safe distances from property and overhead wires, you contribute to minimizing potential hazards.

Optimal Timing for Summer Tree Pruning

When considering summer tree pruning in Columbus Ohio, a key factor to bear in mind is heat stress. Striving to avoid simultaneously subjecting your tree to both pruning cuts (wounds) and heat (or water) stress is crucial.

During summer, resilient trees can initiate the process of sealing off wounds caused by pruning cuts while concurrently generating leaves and harnessing energy from sunlight. Yet, if a tree is grappling with heat stress, undertaking summer pruning could inflict excessive damage.

The prime period for pruning lies in early summer, preceding the zenith of temperatures. However, before you take up your shears, a few other aspects warrant consideration:

Terminal Bud Timing:

Following the emergence of all spring leaves, trees establish terminal buds at the ends of their branches. This signals the cessation of new leaf growth, rendering summer pruning less likely to trigger substantial leaf regrowth. Ideally, perform pruning after terminal buds have formed.

Flowering Schedule:

For trees and shrubs that bloom in spring, prune them prior to the formation of their forthcoming flower buds. Pruning these buds could result in fewer or no blooms in the subsequent spring. Prune spring-flowering trees shortly after their flowering period.

While we encourage individuals keen on mastering tree pruning, it’s essential to familiarize yourself with your trees and their annual growth cycles before embarking on pruning endeavors.

Trees Suited for Summer Pruning

While almost all trees can undergo summer pruning, certain trees reap advantages from this practice during the warmer months.

“Sappy” Trees:

During summer, it’s safe to prune hardwood trees naturally inclined to produce substantial sap, including Birch (Betula species), Maples (Acer species), and Walnut (Juglans species). These trees dispense notably less sap to their branches in summer, reducing the tendency for sap weeping compared to late winter or early spring.

Fruit Trees:

Employing summer pruning for fruit trees offers three distinct benefits:

  1. Stimulating bud growth for the forthcoming year’s blossoms.
  2. Facilitating sunlight exposure to more branches is essential for flower and fruit bud production.
  3. Managing the emergence of suckers and water sprouts.

Augmented sunlight exposure aids in fruit ripening. It’s advised to maintain a leafy crown to shield tender-skinned fruits from sunburn while boosting ripening processes.

Note: Most fruit trees derive greater benefit from substantial pruning during the dormant season, with a gentler touch recommended for summer pruning.

Trees to Avoid Pruning in Summer

Engaging in summer tree trimming can inadvertently create openings for insects and diseases to harm or even kill your trees. Adhering to these guidelines when pruning during summer is essential:

Never prune when tree pathogens and insect pests are active.

Always sterilize your pruning tool blades, preferably between cuts, and at minimum between trees.

Even when adhering to these best practices, exercise caution when pruning the following trees during summer (unless necessitated by failure or damage):


The perilous fungal disease, oak wilt, lacks a cure and continues to spread across the Midwest and eastern states. Pruning cuts attract beetles that carry the oak wilt fungus, making it critical to avoid pruning while beetles are active (April through October). If summer pruning of oak trees is necessary, applying specialized tree paint to the wounds is essential. It’s crucial for everyone to contribute toward slowing the loss of oaks and maintaining forest diversity and specimen trees.


Similar caution applies to elms; defer pruning until fall. Dutch elm disease, a fatal and incurable ailment, affects elms across Columbus Ohio, and beyond.

Though fungicide systemic treatment can be applied preventively to healthy oaks and elms, its effectiveness is temporary and it does not offer a cure.

Abundant Leaf Production

Spring ushers in the emergence of new buds on trees, signaling the transition from winter to summer. The subtle pale green haze that surrounds trees during leaf emergence transforms into the lush, leafy shade of midsummer. The continual growth and intricate structure of leaves never cease to captivate.

Many cherished Ohio trees excel as prolific leaf producers. Due to this propensity, we advise homeowners and tree owners to be vigilant for rapid growth that could potentially dominate a tree.

Depending on your trees’ age, species, and vitality, what once was a neatly composed springtime tree might evolve into an exuberant summer growth.

Closing Thoughts On Can You Trim Trees in the Summer

Winter pruning serves the purpose of maintaining a tree’s branch structure, height, and crown dimensions in equilibrium. However, the robust growth that occurs in spring can swiftly overpower and disrupt the careful shaping achieved during winter.

If you observe your trees transitioning into summer while appearing dense, uneven, or excessively large, it’s advisable to schedule some summer pruning. This practice serves to open up their canopies and enhance their overall shape.

Branches that have grown overly lengthy or are burdened by exuberant foliage are at greater risk of breakage during summer storms. Such breakage can lead to structural harm necessitating corrective pruning.

To steer clear of the expenses and stress associated with this labor-intensive task, ensure that your trees undergo regular inspections and pruning. A touch of preventive care can guarantee your trees a prolonged lifespan and a naturally appealing form.


When is the best time to trim trees in Ohio?

The best time to trim trees in Ohio is during late winter or early spring before new growth begins. This period, typically from late February to early April, is when trees are dormant, reducing the risk of disease transmission and promoting healthy regrowth in the coming months. Avoid trimming during hot summer months or late fall to protect the tree’s health.

Is it Okay to Trim Trees in the Summer?

It’s generally not recommended to trim trees during the summer months if you can avoid it. Summer is when trees are actively growing and stressed by heat, so pruning can further stress them. However, if there are safety concerns or damaged branches that pose a risk, you can trim them in the summer but try to keep pruning to a minimum and avoid major pruning tasks if possible. Late winter or early spring is usually a better time for tree trimming in Ohio.

Will pruning a tree in summer kill it?

Pruning a tree in summer won’t necessarily kill it, but it can stress the tree and should be done with caution. Summer is a period of active growth and energy for trees. Excessive pruning during this time can weaken the tree, making it more susceptible to pests and diseases. If pruning is necessary, focus on removing dead or damaged branches and avoid extensive trimming.
