Living out here in the Yakima Valley means dealing with blistering summer heat, chilly winters, and winds that can test a tree structure. Property owners often ask what is actually necessary versus what is just cosmetic landscaping. The questions answered below are the ones Neighborly Tree gets asked the most out on local job sites in Union Gap, WA.
When is the best time of year to prune trees around here?
For most deciduous trees in our semi-arid climate, late winter when they are fully dormant is the absolute best time. Without leaves in the way, you can clearly see the branching structure, and the freezing temperatures keep pests and fungal spores from entering fresh cuts. Fruit trees, which we see a lot of in this agricultural pocket, also need a good late-winter cut before the sap starts moving. However, if you have spring-flowering shrubs or ornamental trees, wait until right after their petals drop so you do not accidentally remove next year's blooms.
How often do my trees actually need to be trimmed?
There is no single number that fits every single tree on your property. Young, fast-growing trees usually need structural tuning every couple of years to prevent weak unions and erratic growth. Mature shade trees can often go 3 to 5 years between major prunes, provided they are not dropping dead wood or hanging over your roof line. If you notice branches rubbing against your siding or power lines, it is time to call Neighborly Tree regardless of the calendar.
Can I top my cottonwood or maple to keep it smaller?
Tree topping is one of the worst things you can do to a tree's health and lifespan. When you cut the top off a mature canopy, the tree goes into shock and shoots out weak, fast-growing water sprouts that attach poorly to the trunk. Those new branches rot easily and become major safety hazards during heavy windstorms in Union Gap. If a tree is simply too big for its spot, crown reduction done properly by thinning back to lateral branches is a much safer alternative to outright topping.
Will pruning help my lawn get more sunlight?
Pruning Trees can definitely help your lawn get more sunlight. Many yards in Union Gap feature older maples or dense ornamental canopies that block out the sun entirely, leaving patches of thin, struggling grass underneath. Crown thinning opens up the canopy just enough to let dappled sunlight through to your turf without harming the tree's overall balance or exposing its bark to sudden, scorching sunscald.
Should I put anything on the cuts after a branch is removed?
You should leave tree cuts completely bare. Years ago, people used to paint every single cut with black pruning sealer, thinking it acted like a bandage. Research shows trees heal much faster and fight off decay better on their own in the open air. Sealer actually traps moisture and fungi right where you do not want them.
How do I know when a branch is actually hazardous?
Look for dead wood that snaps easily, cracks in the main unions where major limbs meet the trunk, or branches showing fungal growth and conks. If a limb is rubbing against another or growing directly back toward the center of the tree crossing other branches, it is a structural liability waiting to fail when a heavy storm rolls off the Cascade foothills. For homes and businesses in Union Gap, Neighborly Tree provides Tree Service work, and we always tell property owners that if a branch is over two inches thick and looks questionable, it is worth getting a professional set of eyes on it before it comes down on a fence or a vehicle.
