I built a little box to grow some vegetables and used a mix of mushroom manure and topsoil. I'm thinking I should have mixed some peat in there too because the top layer gets pretty hard over the course of a sunny day.
Is there anything I can do now, after I've already planted the seeds, to loosen the soil up?
