Looking for JM with good yellow fall color
After my 2 crepe myrtles died from powderly mildew brought on by drought stress last year, I am looking to buy a pair of JM that have nice green/light green foliage in the spring summer and a nice yellow color in the fall.
I know crepe's are drought tolerant and JM need moist soil. I watered every week with soaker hoses on for an hour and a half when it didn't rain but we had over 30 days in the triple digits and they just cooked. While replacing some pansy's this spring I did find a root from one of the crepes that was over 7 feet from the shrub so I'm kind of stumped at their decline, really.
Anyways live/die this is what I want to try. Space taken up can be up to 10 ft spread and height to 15 feet. They will both be full sun but middle of summer they will be shaded until about 10-11 and then sunlight until sundown around 8-8:30.
