I have mature crepe myrtles along both sides of my driveway. Care has been the same so I don’t think there is any issue there, but on one side the leaves of several trees emerged in spring yellow and red. I’m thinking to take some leaf samples to check for nutrient deficiencies, but thought I’d check here if there were other suggestions as to what could be the cause. I’m in the Central Valley in California, so hot dry summers, although we have had a few wet winters in a row. Any thoughts on what this could be and how to fix?
