Larches are a type of conifer that lose their leaves (needles) for the winter. This sometimes causes people not aware of what they are to think they are dying, despite this being a completely normal process.
Larix species are native to portions of Washington state, among other places. There are a number of species and varieties, including this small weeping one I recently pruned.
This weeping larch hadn’t been pruned (besides “skirting” the bottom) for at least 5 years. Lots of deadwood make the structure hard to see even during the winter after it has dropped its needles.
After removing the deadwood, and selectively thinning some of the live branches in the thicker areas.
