How to get fine tilth?

[winnie]

Hi, when we sow our seeds I have to say say '1 lump or 2' as we arrange the lumps of solid clay around our little seeds!! Actually, that's the quickest way to have me jumping around in frustration and threatening to give it all up & quit. We ALWAYS plant into pots at home first then plant out on the allotment after emtying a grow bag onto the bed first.

I had a patch last weekend that was literally lumps, but had to get it to a fine tilth to get 50 odd onion sets in.

I added some coffee grounds, some burnt soil from another patch of the lottie, some mustard that had grown on a patch at home as a green manure and some sand. I dug it in for ages but still had lumps.

All the lumps got taken out and put into a pile ready to be broken down once they had dried out a bit, and bingo - a fine tilth. It took a while but all the sets sent in last weekend and are looking good now.
