Q.Burning bush has not grown in a year.
I bought about 10 burning bushes that were 4 to 5 inches tall, little or no leaves. This was a year ago. They haven’t grown that I can tell and very, very few leaves. Some have no leaves. Are they dead or really slow growers?

Check the stems for signs of scale or fungal issues.
