Snow on the Mountain getting crowded out

Question

I planted Snow on the Mountain several years ago in a shady spot and it did well for years. Around August it would start to get brown so we would cut it and it would come back looking nice. A couple years ago, other weeds started growing in what was a solid patch of Snow on the Mountain. Now it is competing with other plants. Do I need to do something with the pH of the soil or is there another solution?
Thank you

Answer 1

Generally Snow On The Mountain needs little care. It can become invasive, I have not had an issue with that myself.
You could use an all purpose fertilizer to give the plants a little boost. If the soil needs some amending, you could top dress the soil with some compost.
