The last couple years, my redtwig dogwood was prematurely turning bright pink leaves on half the plant about early to mid summer. The stems are brown with white spots on them. Brought pieces back to where I purchased at a nursery and they said water issues. Again this year it happened, I pruned it down in late spring and the leaves grew back bright green normal color. Mid summer they instantly died and now half the plant is like this, maybe more than half. See images. One shows the pink leaves I was referring to, which were half the plant last year. Another pic shows the dead half vs the still good half.
