There are several Louisvillians who have reported that their Crepe Myrtle trees have not yet bloomed this summer, including mine. There are new growth shoots all over the trees and the leaves look very healthy but only 1 of my crepe myrtle trees out of 4 of the crepe myrtles I have in my yard (within close proximity) are blooming. I have been watering them when it doesn't rain and just today put some bloom food on them for the first time this summer. Usually by the first week of August they are so full of blooms they are drooping.
I drive down the road in Louisville and see other crepe myrtle trees blooming but then as I mentioned I have other family/friends who own crepe myrtles that are experiencing no blooming yet.

Is there anything else I can do at this point in the summer that will help to encourage my crepe myrtles to bloom? Anything to add to the soil other than the bloom food I just put on today?

Is there any possible chance that the CICADAS had anything at all to do with this? I noticed how all trees have the dead ends to them that fall off that the Cicadas scratched on. Would this have made a difference in why are crepe myrtles are slow to bloom this year?

If I am seeing tons of new growth...can I expect that they will still bloom before the end of the summer like they normally do?

Thanks so much for your input! They were all planted in memory of loved ones so the joy I receive to see them bloom means a lot!

Lack of flowers can be caused by a number of different situations: lack of sunlight, competition, weather conditions, lack of nutrients, improper pruning, etc. This has been something of an exceptional year in this regard, and as you mention, lots of people have been concerned obout the lack of flowers, not just in shrubs, but also fruit trees and vegetable plants.

You mention cicadas, and yes, this might be part of the problem. Check the stems for the tell-tale vertical slits in the stems. Lots of damage would certainly affect flower production.

It could also be excessive nitrogen fertilization. Lots of high nitrogen fertilizer will produce green leafy growth, at the expense of flowers and fruit.

Because of the spring weather we had, things are also a little set back now. I've been saying that we are about three weeks behind. So the good news is that as long as your plants are healthy, you still should see good bloom by the end of the growing season.
