I think it likes it in there.
As do the grape and Roma tomatoes (at least I think they're Romas, they're compost volunteers), the peppers, the baby avocado trees and the infant apple trees I planted from seeds (but the Meyer lemons haven't peeked out yet). With the greenhouse door open all the time, it stays a relatively stable 80 degrees.
Now I need to think up another project to use more Irish Moss. It's coming up again in amongst the onions and potatoes.
Don't mind the beer can. It's a slug trap.
Maybe I'll put it around the stones in the garden entrance. The oregano is taking too long to spread. If you have a small area where you'd like a low, hardy, pretty - it has tiny white flowers when it blooms - ground cover, I'd recommend Irish Moss. It gives a really good return on your investment.
There's another ground cover we use a lot. Of the two, I'd have to say Irish Moss is the best. It wears better in foot traffic areas, but I'll post about that another time.
