When Is the Best Time to Trim Trees in Humboldt County?

Trimming your trees at the right time can make all the difference between a healthy, thriving tree and one that struggles to grow—or worse, becomes a hazard. Here in Humboldt County, where our climate shifts between rainy winters and dry summers, understanding when and how to trim your trees is key to keeping your yard safe, beautiful, and full of life.

At True Tree Service, we get a lot of questions about the best time to trim trees. The answer depends on the species, your property goals, and the condition of the tree. But don’t worry—we’re breaking it all down for you right here so you can plan your tree care the smart way.

Winter and Early Spring: Prime Time for Pruning
In Humboldt’s cool, wet winters, many trees go dormant—meaning they slow their growth and conserve energy. This is the perfect time to prune most deciduous trees (like maples or oaks), because without all the leaves, we can easily see the tree’s structure and make clean, strategic cuts.

Winter pruning helps prevent the spread of disease, encourages healthy spring growth, and improves the shape and stability of the tree. For fruit trees, early spring is also a great time to trim to maximize yield. We always recommend pruning before new growth starts to appear—usually between late January and early March in our area.

That said, not every tree likes a winter haircut. Some species, especially flowering trees or shrubs, do better when trimmed after they bloom—more on that next.

Late Spring and Summer: Timing Is Everything
Once trees start to leaf out and flower, trimming gets more delicate. If you prune too early, you risk cutting off this season’s blooms; too late, and you could stress the tree. For trees that flower in spring (like dogwoods or cherry trees), it’s best to trim right after their blooms fade.

Summer can also be a good time to lightly shape trees, remove dead or damaged branches, and handle urgent trimming needs. At True Tree Service, we pay attention to tree health signs like drooping limbs, pest infestations, or weak spots. If something looks risky, we’ll address it—no matter the season.

If you're unsure whether your tree needs a mid-year trim or should wait for the colder months, our team can come take a look and give you honest advice based on local conditions and tree species.

Fall Caution & Year-Round Tree Health
Fall might seem like a good time to prune—after all, the weather is cooling down and leaves are falling—but for many trees, it’s better to hold off. Trees are starting to go dormant, and pruning at this stage can slow the natural process or open the door to fungal issues and pests.

Instead of trimming in fall, we often recommend focusing on tree health and cleanup—removing fallen limbs, checking for signs of disease, and preparing trees for winter storms. If a tree poses a safety risk or shows signs of serious decay, our team at True Tree Service can safely remove or stabilize it before the bad weather hits.

Healthy trees add value to your property and beauty to your landscape—but only if they’re cared for the right way at the right time. That’s where we come in.
