The Q&A Archives: Silver mound

Question: My beautiful silvermound was doing beautifully all spring and summer - it grew and spread and was thriving until about a month a ago and now it seems to be dying off in sections. What can I do to restore it or is it going to go dormant for the fall/winter? THANK YOU!!!!!

Answer: Silvermound often collapses in late summer primarily due to the humidity. Be sure it is planted in full sun with good air circulation, do not overfertilize it and do not let it become overly crowded.Also avoid wetting the foliage -- it is very drought tolerant so should not need much if anywatering anyway. If you shear it back in late July (just when it begins to look bad) this can stimulate a late season growth spurt that will look a bit better for the fall season. At this point you can trim out any dead portions but it will not have time to recover much before freezing weather. In the spring, trim it back very short and it will regrow fresh foliage. I hope this helps.
