Drive through the older neighborhoods of Nampa, Caldwell, and Boise's North End and you'll see them everywhere: huge Siberian elms, silver maples, and willows planted decades ago because they grew fast and gave shade quickly. That fast growth came with a trade-off that homeowners are still living with today.
These species produce relatively weak, brittle wood. They also tend to form tight, narrow branch unions and sprout clusters of fast-growing shoots wherever a limb was cut or broken in the past. As the trees age, interior decay is common, and a limb that looks healthy and fully leafed out can fail on a calm day, not just during a windstorm or an early wet snow.
That doesn't mean every big elm or silver maple needs to come down. Regular pruning to reduce heavy end weight, remove deadwood, and thin out weakly attached sprouts can make a mature tree much safer, and our ISA Certified Arborists can tell you when a tree is a good candidate for that and when it's reached the point where removal is the responsible choice.
Do you have a big elm, silver maple, or willow on your property that's older than your house? #TreasureValley #TreeCare
