It’s actually pretty cool to see moss showing up on a path – it’s a natural way of keeping the soil moist and adding some texture. If it’s just a thin layer, leave it; it can help hold the stones together and feed the tiny microbes that turn leaf litter into good compost. If it starts to get dense and you notice weeds pushing through or the stones getting slippery, a quick trim will keep the path tidy without killing the whole micro‑sanctuary. Just remember to rake the moss gently and leave the debris in a compost pile so it can feed the soil again.
