What's wrong with our Mexican Redbud tree?
We planted this Mexican Redbud 3 or 4 years ago. Each spring, it blooms and leafs out beautifully. By late July, however, the leaves begin to blacken at the edges and become brown and crispy. (Our neighbor's young Redbud does the same but less severe. Theirs is in partial shade, ours is in full sun.)
We water 2-3 times a week with a five gallon bucket with a small hole drilled through the bottom placed under the drip line. This is in addition to the lawn irrigation. We feed in spring and fall with Trifecta.
We'd appreciate any wisdom this community has to offer! Thanks!
