Get yourself some well rotted muck - horse or cow- if at all possible and either dig it in or use it as a mulch and let the worms work it in over winter. (this helps with the weeds but isnt as good for the soil) I do my beds around October when everythings harvested, but you can start now.

Id dig it in roughly (if you can dig your raised beds) and let the frosts break the clumps down over winter and then give it a good dig in spring

Bear in mind though, you cant put muck in a bed where carrots or parsnips are going to live

If you've got really solid clay (can make a ball with it when wet), then after Peapod's muck in Autumn, it would help to spread some lime in Spring. But you're not supposed to use both at the same time.

I built my raised beds because I have clay soil.  Unless you are willing to work very hard you won't get them perfect for next year, but much improved.  I threw in everything I could afford compost wise and a load of sharp sand.  As you dig and break down the clumps add more sand.  As the others say, add loads of well rotted manure and wait for spring.

Don't fill the beds up to the top as you will be adding to them over the seasons anyway.

I wouldn't put manure in a bed that you are going to put winter cabbage in.  Blood, fish and bone would be my choice.

I would add any kind of manure (well-rotted or not), garden compost, mushroom compost and anything you can get on areas that will not be planted until next spring so the winter weather can do its stuff (except where you are going to plant carrots and parsnips next year). On areas to be planted now, I would dig in sharp sand and / or grit to open up the soil structure. This would also needed to be added when you dig in the manure etc next spring then add BFB on planting as Ice said. Add lime in spring for your brassicas each year as you rotate your crops. This flocculates (binds) the clay particles and opens up the soil.

thankyou, i can get fresh horse poo(very fresh), is this ok to put on the soil?,

Get both, build yourself a 3 sided box out of pallets and line with plywood/thick cardboard, tarp or something to keep the wind from drying it out, make a door for the front for access and put your fresh poo in, for future years etc.

Mine last year was quite fresh.  I put it on the beds in October and planted spuds in March, when it was quite broken down but not fully.  The spuds have been great this year, but cant vouch for another veg putting up with that

Be careful that the muck you put on does not protect the soil from winter weather. Dig in muck in the Autumn before the soil gets too wet. Leave it in rough clods over Winter for the weather and frost to break it down. Keep off it in the Spring until it starts to crack and crumble as it dries. What is known as going mouldy. Better to wait a little in the Spring than to get on too early and spoil what the weather has done for you. This may be an old fashioned approach but it works.

As advised in some of the above posts the best thing you can do with clay or any hard ground over winter is to dig it in the autumn leaving the clods as large as possible. Use the fork and don't break the clods up. A few hard frosts and the lumps will break down in the spring with a rake or fork.

You can dig any muck in at the same time, which is my favourite option, or leave it on the surface in Spring.

hi, i have just put a layer of about 2inchs (i think), of mixed horse poo(rotted and some fresh), on and covered it with black plastic stuff, is this ok?, i didnt dig any soil under it as it was a bit on the hard side...

Rather than black plastic, try putting down cardboard. It will degrade with the poop, keep in moisture and the lower soil will be soft by spring. Only catch is you'll have to put rocks or bricks to keep the cardboard from flying away in winds.

Trillium's right, plastic over winter can cause some other problems - see Clover's recent post here (http://chat.allotment-garden.org/index.php?topic=45309.msg532127#msg532127), where the ground ended up compacted and the manure did not get worked into the soil

ok, i'll take the plastic off, what about weed control stuff on top( lets the water in and some off the heat in)???, if not i will have to look for cardboard only draw back is i will need loads..

Try to find yourself a nice friendly lawn mowing service.... there's still sometime left for cutting lawns. A thick layer of grass mowings wont blow away, wont stop the air getting to the ground and manure below, will add to the humus and is a more natural alternative to cardboard, far better than plastic, cheap, will help the lawn mowing service as they'll have somewhere to dispose of the grass and.......works for me!!

It is dragged into the ground by the worms and is easily dug or rotovated in during the spring.

Just a thought.... that some may disagree with...but there we go.  ;)

thankyou for the idea, i will ask around for grass cutting..

thankyou for the idea, i will ask around for grass cutting..

a combination of areas of grass and patches of cardboard should be ok if the mowing season is slowing your way...

I have a huge compost bin and a mate who cuts all season.... he layers bags and bags full of grass into the bin - I add shredded paper, annual weeds and any compostable green waste from the plot...as well as shrub shredding from home. Dug in this adds to the humus and lightens the soil. Spread on top it makes a good mulch in spring to supress some of the weeds and keep in the moisture....

Only caution - avoid newly "weed & feed" treated mowings directly on the plot - compost first for a few months. You tend only to get this in the spring...

Have fun!!
