What Your Trees Need Right Now
Spring in the Willamette Valley moves fast — and so does the window for doing tree work right. Here's what's worth knowing right now.
Oregon White Oak (Garry Oak)
May is one of the last good months to prune oaks before summer risk increases. ISA guidance and Oregon Department of Forestry research both identify June through September as an elevated period for fungal infection through fresh pruning wounds. Right now, the tree is actively leafing out, structure is visible, and wounds callous quickly in the warming temperatures. After June, we don't typically prune oaks unless it's a safety issue — so if you have an oak that needs attention, this month matters.
Douglas Fir & Big Leaf Maple
Both species respond well to spring structural work. The active sap flow in May means wounds seal faster than at any other time of year — what takes months to callous in fall closes in weeks now. If either species has limbs that are competing for dominance at the top, this is the right time to address them.
What we look for in May:

Winter storm cracks in major scaffold limbs (our Pacific storms are hard on lateral branches). Bark that didn't close from a previous wound. And codominant stems — two trunks of nearly equal size competing at the top of the tree. That last one is the most common cause of catastrophic failure in mature trees. Catching it while the tree is young enough to guide is the whole game. If something on your property has been on your mind since the last storm, May is the right time to get eyes on it before summer growth hides the structure again.
