Short version: Did any of you try moss as a mulch? Did you get slugs? What about woodlice?
I read this very excited article (In Danish) about using moss as a mulch to inhibit slugs. Slugs have been quite a problem in my experimental amateur garden, and ironically, so has drought, so it seemed a nice solution, or at least a nice try.
The original article killed the moss in a grass lawn with iron vitriol, then added it in a generous amount to a garden bed. I try not to use chemical poisons, so I have just been ripping it from the grass, then adding it on a newly loosened bed with compost. I have some good 10 cm of moss, maybe more.
So far it has been a mixed success. It keeps the moisture nicely, but it also keeps the cold, so I think I was a bit too fast putting it on the beds; I could have waited until it warmed a bit. I have seen no hint of the fava beans I sowed, underneath it, and I would have expected them to show up by now.
On a more serious note, several of the pole beans I planted the other day have been gnawed over, seemingly by woodlice (isopods). No slugs (so far), but still something eating my plants. 😠
Has any of you had problems with woodlice?
My soil is notably poor, so the earthworm population is fairly low in most of the beds. I have seen woodlice in my father's greenhouse and in a kitchen "worm" compost, so it seems like they and worms fill out a similar niche.
