Neighborhood volunteers will finish removing ivy and pruning trees along Holman Road Northwest on Saturday. The outside southbound lane of Holman will be closed from 13th Avenue NW to NW 87th Street from 8 a.m. to 3:30 p.m. The volunteers will have support from Seattle Department of Transportation’s Urban Forestry crews.
Removal of invasive vines is important to the health of trees. Ivy will quickly grow up the trunk of a tree, smothering the tree’s branches, and eventually killing the tree. Even when kept only around the base of the tree, ivy still robs the tree of nutrients and can cause rot in the trunk which can lead to tree falling over. Also, trees that have their canopies covered with ivy may not be able to withstand the additional wind or snow load caused by the extra leaf area of the vines.
