You're in conifer land, so, either up high, or up north (in the northern hemisphere)
So the soil must be acidic. Not much topsoil i'd guess, stoney gravely soil may be?
And for the mulch, may be seed it, stuff it in barrels, with some frequent sprinkle of water and roten wood.
I would burry it a bit, rather than leaving it on top.
Don't spread it too thick too...Don't ever use conifers for mulch!
Roten straw works quite nicely too.
But when I used mulch in the greenhouse, it has done all that lovely mulch stuff. The greenhouse is more humid, and I water with buckets so I don't get that flowing problem. The bottom of the mulch turns black and rotten, and the soil below it gets all dark and soft and damp and nice

That's an interesting thought. How big is your greenhouse?
They're supposed to be pretty neutral. The acid comes out in the drink. I've never tested for PH. I'm told that everything here is horribly acidic, but when I plant stuff, I have to jump back to avoid being hit by the emerging growth.
The coffee is spread on the surface. Bugs drag it around. Tomatoes, peppers and eggplants are given a cover of coffee with no other mulch. The dark color makes the soil warmer.
Gravity is a harsh mistress. But this tiny ad is pretty easy to deal with:
