i planted this shrub a little over a month ago. i've noticed the growth, mostly near the base of the plant, are turning a yellow/pink/red color---a few appear to even have a little black on them. a few have just turned plain red. some of these "discolored" leaves will fall off just to the touch. don't believe moisture is the problem---between hand watering during our "hot stretch" and the rains, it's been quite sufficient.
this is my first experience with barberry, so, just wondering if this could be stress from the planting, or, might this require some type of spray regimen? really hoping not to lose the shrub.
btw, it is planted near the walkway on west side of house. starts getting sun around 11am or so, and lasts till almost sunset. so, sun shouldn't be the problem.
