While many homeowners only think about protecting their trees once the wind starts howling, the most effective protection happens before storms start blowing through. Proper previous planning can mean the difference between a tree that weathers the storm and one that crashes through a roof and has you scrambling to file a homeowners insurance claim. […]
TL;DR: Newly planted trees need close attention for the first 2 years, especially with consistent watering. Use a watering bag or ring and plan to water frequently in the first seasons, especially during hot 90°+ days. Keep a turf- and weed-free ring around the trunk and add 3–4 inches of mulch (kept away from the […]
TL;DR Watering needs vary by season, with deep watering required during hot summer months and less frequent watering in cooler weather. Water at the tree’s drip line, focusing on deep, slow watering to 12-inch depths for best absorption. In summer, check soil moisture weekly and water more often during extreme heat or dry spells. Winter […]
TL;DR Tree roots are shallow and fragile: Most critical roots sit in the top 2–3 inches of soil, and patios installed over them can block water, air, and nutrients. Poor planning causes permanent damage: Cutting roots, compacting soil, or installing patios without early planning can severely stress or kill mature trees. Root Protection Zones are […]

TL;DR: Mulch supports tree health by improving water retention, moderating soil temperature, reducing stress, and preventing weeds and compaction. Apply 2–4 inches of natural mulch in a wide ring around the tree—never touching the trunk—to avoid oxygen loss and fungal issues. Avoid common mistakes like over-mulching, using poor-quality materials, or creating “volcano” mulch piles around […]
TL;DR: DIY tree pruning is dangerous—tree trimming is one of the highest-risk jobs, especially without proper training and equipment.

TL;DR: Trees clean the air we breathe and can directly reduce illness and mortality rates. They filter and store a major portion of our nation’s water supply, helping keep waterways clean. Trees boost property value significantly—sometimes by 10% or more. Exposure to trees improves mental and physical health, even speeding hospital recovery times. Trees also […]
TL;DR: Mower blight occurs when lawnmowers or trimmers repeatedly strike a tree’s trunk, damaging bark and restricting water and nutrient flow. Trees are especially vulnerable in spring and fall, but careless lawn care can cause injury year-round. Mulching around the base of a tree helps prevent damage, reduces weeds, and creates a clear buffer zone […]
TL;DR: Tree topping is harmful and increases hazard risk rather than reducing it. Pruning doesn’t automatically boost tree health—over-trimming can weaken a tree’s ability to produce energy. Concrete-filled cavities damage trees by causing internal abrasion and decay. Branches don’t regrow in the same place, making improper cuts permanently damaging. Staking and ignoring dead branches are […]
TL;DR: Planting a live Christmas tree outdoors after the holidays often fails because the tree wakes up indoors and then goes into shock in winter temperatures. Most Christmas tree varieties grow too large, too wide, or too short-lived to make good long-term yard trees. The decorative shearing used to create the “perfect” Christmas tree shape […]
TL;DR: Fall is the best season to plant a new tree thanks to cool temperatures, steady rain, and ideal soil conditions. Pick tree species suited to the Pacific Northwest, especially evergreens like Douglas Fir or Western Hemlock. Choose a healthy tree with a single strong trunk, no pest damage, and roots that aren’t circling the […]
TL;DR Trees and shrubs too close to siding can cause damage, including scraping, mold, and pest infiltration. Regular inspections and pruning every 3-7 years are essential for preventing siding damage. Plant trees and bushes at least ten feet away from structures to avoid future issues. Dead branches or overgrowth can lead to serious damage, requiring […]
TL;DR Tree roots lifting sidewalks can be a costly and recurring issue for homeowners, especially in Portland. Avoid cutting roots or using tree growth inhibitors, as they can harm the tree and lead to further sidewalk damage. Preventing root damage starts with proper tree planting and the installation of root barriers or protection zones. When […]

TL;DR: Trees near electrical power lines pose serious safety risks, and responsibility for trimming them falls on utility companies.
