2 Purple Dragon have been withering since I planted them in May. I cut off the withering & slightly slimy stems since I didn't know what else to do with them. They get new growth that looks nice and shiny for a week or two and then revert to that withering.

A Silver Beacon has spread like wildfire that I planted in June. I just noticed yesterday a couple stems were doing the withering routine. They don't get dry but seem overly moist.

I'll go with your experience, tangerine, and keep cutting them back when they get that wet, withered look.

Seems like leaves don't like touching ground very much as they brown up wherever they're not held up on stem. Guess that's part of their nature too.

The Silver Beacon is racing past its intended space. Was thinking of cutting it back and rooting it to spread around more plants but just occurred to me that might be its natural habit and won't take moisture/nutrients from plants it rambles around. Does it encumber other plants if it wends its way around them when Lamium not cut back or is it a friendly wanderer around upright plants? Silver Beacon has a few stems which have self-rooted themselves in soil. Didn't know they did that!

So much to learn with so many different plants.
