Liriope’s Muse: Tree Care Tips from a Master Arborist

Liriope's Muse - Timing is Everything: The Best Time to Prune Your Trees for Healthy Growth



One of the most common questions that our ISA Board Certified Master Arborist, Eric Putnam, receives from tree owners is: "When is the best time to prune my trees?" The answer isn't always straightforward, as it depends on various factors, including the species of tree, its health, and your pruning goals. In this blog, in collaboration with Eric, I'll provide valuable insights into the best times of the year to prune trees for optimal results.

Understanding Tree Dormancy

Before delving into specific seasons, it's crucial to understand the concept of dormancy. Dormancy is a period during which trees experience slowed growth and metabolic activity. This phase typically occurs during the winter months in temperate climates, although it can vary depending on the species and environmental conditions.



Pruning during dormancy offers several advantages. Firstly, without the presence of leaves, it's easier to assess the tree's structure and identify areas that require attention. Secondly, dormant trees are less susceptible to stress and disease, reducing the risk of complications from pruning wounds. With these principles in mind, let's explore the best times of the year to prune trees.

Late Winter to Early Spring: Ideal for Most Trees

For the majority of tree species, late winter to early spring (or before the trees break bud) is considered the optimal time for pruning. During this period, trees are dormant, making it an excellent opportunity to perform corrective pruning, remove dead or diseased branches, and shape the tree's structure. Pruning during this time stimulates new growth as the tree transitions into the growing season.



However, it's essential to avoid pruning certain species, such as pines and birches, during early spring, as they are prone to "bleeding" – the leaking of sap from pruning wounds. While bleeding is not directly harmful to the tree, it can attract pests and some individuals find it unsightly. To minimize bleeding, consider postponing pruning these species until late spring to early summer or don’t .

Summer: Ideal for Maintenance Pruning

While summer is not typically the primary pruning season, it's an ideal time for maintenance pruning and light trimming. During the summer months, trees are in full leaf, allowing you to assess their canopy and address any overgrown or crossing branches.



However, it's crucial to avoid heavy pruning during the hottest months of summer, as it can stress the tree and make it more susceptible to environmental stressors like pests, fungal infections, and disease. Instead, focus on minor pruning tasks, such as removing deadwood and shaping the tree's silhouette.

Fall: Best for Specific Tree Species

Fall pruning is best reserved for specific tree species, particularly those prone to diseases such as oak and elm trees. With insects and pathogens less active during the cooler months, fall pruning minimizes the risk of infection from pruning wounds. Additionally, fall pruning allows you to address any structural issues before winter storms arrive.



In conclusion, the best time to prune trees depends on various factors, including the species of tree, its health, and your pruning goals. By understanding the principles of dormancy and selecting the appropriate pruning season, you can promote the health, vigor, and longevity of your trees. If you're unsure about the best time to prune your trees or require assistance with pruning techniques, don't hesitate to consult with a certified arborist for professional guidance. Happy pruning!



At Eric Putnam BCMA, Inc. we do things a little different than other tree service companies, typically we prune no more than 5% of a trees canopy at a time and remove branches no larger than an inch in diameter, which causes minimal stress to the tree allowing us to prune year-round(with the exception of removing large deadwood and clearances). For expert tree trimming and pruning services in the greater Houston area, contact us today!

*We are located in Hardiness Zone 9B, which is where the majority of our knowledge lies. Note, pruning techniques and timing vary from hardiness zone to hardiness zone.
