The Big Five: Trees Every South Sound Homeowner Lives With
Douglas fir, western red cedar, bigleaf maple, cottonwood, and Garry oak — what each one does, what each one needs, and when each one worries us.
Douglas fir: the towering default
The tree that defines our skylines and our work orders. Doug firs are strong, long-lived, and comfortable at 150 feet, which means the one in your yard is probably the largest living thing you’ll ever own. Their weakness isn’t the wood; it’s the sail: dense crowns catch winter wind, and on saturated soil whole root plates can lift. Open-grown firs and retained forest trees that lost their neighbors are the classic candidates for wind-sail thinning. Watch for: thinning tops over multiple years, root-flare fungus, and any new lean.
Western red cedar: the graceful worrier
Cedars are beloved for a reason — graceful, aromatic, wildlife-rich, and naturally rot-resistant. Lately they’re also the region’s canary: drought-stressed cedars across the Northwest are showing top dieback, and a browning crown tip is worth a professional look rather than a shrug. Cedars also commonly grow multiple tops, which age into the split-prone unions that cabling exists to protect. A cedar is usually a keeper; keeping it sometimes takes hardware.
Bigleaf maple: the generous shedder
Huge leaves, honest shade, spectacular autumn color, and a lifetime habit of shedding limbs. Bigleaf maples grow fast, multi-stemmed, and heavy, with unions that weaken as trunks expand against each other. Mature maples near structures reward a regular crown-care cycle: deadwood out, weight reduced over targets, weak unions cabled or resolved. They’re also the tree most often butchered by topping crews: a topped maple regrows into a hydra. Please don’t; proper reduction exists.
Black cottonwood: the fast-growing liability
Cottonwoods are the valley’s speed champions, and speed is the problem. Fast growth builds weak, brittle wood that drops limbs without ceremony, sometimes on windless summer days. Along the Puyallup and other river bottoms they’re fine neighbors at a distance; over a roof, they’re the local tree we most often recommend either managing on a tight cycle or removing outright. If you have a big one near a structure, have it looked at. That’s not sales talk, it’s pattern recognition from too many emergency calls.
Garry oak: the irreplaceable one
Washington’s only native oak survives in scattered pockets — Tumwater and the south-county prairies hold some of the best. Slow, tough, drought-adapted, and essentially irreplaceable on any human timescale, a healthy Garry oak should outlive everyone reading this. They ask little: cold-season-only pruning, protection of their root zones from compaction and lawn irrigation, and an owner willing to tell removal-happy contractors no. If you have one, you have a responsibility we’re glad to help you keep.
