Recycling compost from last years tomato growbags
I'm quite new to gardening and I think this is my first post here. I've just taken over the garden and have been through the seed inventory this evening and realised I'm quite behind on potting and germinating.
I need to get my potting done sharpish but have no potting compost and I'm on a zero budget. The compost hasn;t come to much from last year, Theough the C/N ratio is fine, there isn;t enough heat in there and there's not much humus at the bottom. Neighbours have been putting non-chopped up stuff in the compost bins, it has been colder than normal and due to critical illness in the family I didn't get the change to put more insulation round the compost bins
Can I recycle the compost from last year's tomato growbags? How could I sterilise it of for example blight microorganisms ? In the oven / microwave? There are various soil additives in the shed, bloodmeal, fishmeal, chicken waste if neede., It's not for potting tomato plants I know not to plant the same crops in the same soil twice. I want to get the peas, sprouts, broad beans, leek, cucumber and other Jan/Feb crops started off.
Any advice would be appreciated
