Around my pond, and around my garden in general, I have a few patches of moss and lichen. And I think they are a very misaligned plant. While they can be a pest at times, such as in areas where young, tender plants are pushing up they can block them and essentially kill them. And on paths they can be slick when wet and potentially dangerous. But in other areas? I personally think they can make something mundane look a WHOLE lot better
Take, for instance, my rock border edge. What was once a nice enough slab of Yorkshire stone is now a beautiful, aged part of the living organism that is my garden!
You will notice that the rocks on this side of the garden don’t have anything like as much lichen or moss on them as so look… Kinda boring? Nothing like the other side of the garden!
The same for the rocks around my pond. The different types of moss give the whole thing a sense of character. And in summertime they change colour, have tiny flowers and make the whole thing… Better.
And then there are the bonus aspects to allowing moss to take hold. Above is my raspberry pot. I allowed the moss to grow because it does two things. One, it acts like a mulch in that it holds water in the soil, but it also insulates it to keep it cool when warm and warm when cool!
Note that moss does not take any nutrients from the soil so don’t worry about any leeching occurring. The plants won’t require any extra feeding because of the moss being there.
And then there is the last thing… It’s beneficial to some insects and frogs and a few other amphibians love it!
So… For me at any rate, moss and lichen are good when in the right place.
