We live in NW Portland off of highway 26 and 185th Ave up against Rock Golf Club's course. We have 2 Dogwood trees planted at the same time in 2021. They are in a location where we had an old Atlas Cedar that had begun dropping limbs and we took it out and had the stump ground up. Our soil is predominantly clay but has had amendments put in over the years (we've been in our home for almost 34 years). Both trees have been similarly cared for with watering, (currently every other day once the rainy season dried up a few months ago), and occasional mulching (shredded Doug fir and peat moss). Both look great upon budding leaves and braques (especially good this year), and then, the tree closest to the golf course, annually goes into this phase where it dries up, regardless of how much water it receives. The trees are only about XX' apart. I d note some curl on the "healthy" tree. What's the issue with these?
