First off Welcome to The Garden Helper's Forum!!!
We are very glad you found us....
Next I'm just letting you know, I'm going to move your post down into plants
You'll get a few more responses to your question
And I'd like to offer a small bit of help here too, Some questions actually..
What kind of soil do you have your BES in?
Bagged or regular garden soil?
What kind of fertilizer's have you used?
***I personally NEVER use any on those types of flowers
* but we need to know... especially the brand and or numbers on the package...
What locations have you moved them too?
How many times have you moved them?
And how many plants
did you start out with????
And how much watering did you do?
And what time of day, ie; morning, late evenings?
And finally, we have several members from Maryland here, our own Loz, hostess, is from there too!!!!
