Sorry to post about such a mundane topic, but I'm not sure who else to ask! Bought three sacks of peat free compost from my local garden centre. Have been using it to fill trays and small pots for pricking out seedlings, and am constantly having to remove material that hasn't rotted down - woody lumps, smal twigs/sticks and even bits of non-organic material. I've also noticed that it dries out very quickly - I didn't think I should be watering dahlia tubers before they've sprouted, but the compost I've potted them up in was bone dry within a couple of days. I thought I was buying good quality compost but this feels worse than stuff I've used in the past. Or are my expectations wrong? Is this normal?
