Background: My husband and I bought a house last year with a couple of acres of land around it that haven't been maintained much recently, although there was obviously someone who did a lot of work on it at some point in the past. Although we've gardened a bit in small urban gardens, we've mostly rented and moved frequently up until now, so we're novices when it comes to composting and other such long term tasks. Location is the West of Ireland, but not right on the coast, in case that's relevant.
Scenario: One of our first tasks this spring as the weather started warming up was to clear the overgrowth (mostly grass and moss) out of the flowerbeds. The earth is so soft that in a lot of cases just pulling it up by hand brought up a lot of earth on the roots, and we also had to dig up a lot of weeds, so we ended up with a debris pile that was probably almost half earth as well as grass, moss, weeds and other plant matter. We separated out the obvious large stones and other unwanted items such as broken pots and bits of rubble. Only one flowerbed is done so far so we'll have the same situation a fair few times more before we're done.
Question: I suspect that due to the large proportion of earth, this pile is not suitable for composting? In any case we're not quite set up for that yet. What is our best use for it, given that we would like to improve the quality of the soil, which tends to be soggy, as well as avoiding unsightly heaps scattered around?
