So a customer wanted a small crape myrtle put in place of an ornamental grass that was in the bed. Put the one in and it failed...leaves curled (looked as if dried out) and started falling from the top and worked its way down. It was getting plenty of water. Replaced with another one and put that one on my dads property...The one we put in the 2nd time looked good, flowering and healthy...started doing the same thing...lost all the flowers...this year it came back looking healthy as anything ...gave 2 shots of fert this spring and now after completely filling in and looking good..it looks as it is going to start doing the same thing again... have tried fungicides and doesnt seem to do much (dont see any signs of insects).....could it be the soil? the first one we moved to my dads that did this in that location looks to be in good health and no longer having the issue. What do you guys think? soil? we mixed some peat moss in when planting but wasnt the best looking soil to begin with.
