Sorry for the late reply. I'm digging a lot in my garden lately. I mainly use the soil in it and add leaves to it. I have a lot of them partly changed into compost already. The new compost heaps I might use next year or within two years I don't know. I have some parts where I put trunks or wood from the trees or cut them down for the stove. Notice yesterday and today a spot where it looks more like peat. I have peat too on the roof tyles so if I have time I'll remove it and add it to my compost heap. Variety is the key but I don't have much kitchen scraps and can only use a few egg scales (the rest I save for the chickens or us, hope those chickens will arrive in May) next to it I have ash (potash) saved from the stove during winter but I'm not sure yet if I need it. The soil is not everywhere the same and to some plants, it's not needed or it will even harm them.
I will add the use pot soil to it too once I replant the plants or they die so I can use it again next year or next year. Keeping a diary and will see if I'm able to grow anything and what the bottlenecks are. At the moment it's rain.
