Multi-purpose compost as soil conditioner?

I am filling a few raised beds in my back garden. Basically I dig up the soil around and put it into the beds. But the soil is clay-ish and is not quite enough to fill up the beds. Can I use the multi-purpose compost from shops as a soil conditioner (as well as space-filler of course)? I know home-made compost is good soil conditioner but these multi-purpose compost from shops are mostly peat. Will it do the job that home-made compost can do?

Thank you very much

 

Cant do any harm. If possible I would add a bag or two of sharp sand in there and if you can get your hands on some leaves or pine needles in the autumn chuck some of that in too.Couple handfulls of chick poo wouldnt hurt either.

 

I agree with Wee Tam it can't do any harm but being compost it will eventually rot down.

 

Thanks. Can I put all the weeds I pulled out in the bottom of the bed? I fear they will regrow although they are already dried under the sun

 

Drying in the sun will not kill all the seeds that may have formed and they could well be still viable. However if you bury them deep enough they may not be a problem.
I try to avoid putting seeded or seeding weeds onto my compost heap or into our worm bins as there's always a few seeds that survive composting.

 

Maybe try and get some horse manure. Most people who have horses are more than happy to give the stuff away. You may have to go and get it yourself in bags tho. If you aren't planning on planting up the raised beds straight away and only start to use them next season then you could put the manure straight on them and by next Spring the manure should be rotted down enough, otherwise you may have to store it if you have room. The manure will break down so you would want to pile on loads so that the level is well above what you would want the level to be eventually. Manure has the advantage of being likely to be free and is a great soil conditioner for either very clay or silty soil. It also contains relatively low levels of fertilizer which just about all plants benefit from.
If the above doesn't seem suitable for you then yes you can use multi purpose as others have said altho personally I'd use Peat as the fertilizer in the multipurpose will be short lived so you are just as good with Peat. Often at the end of the season many garden centres/supermarkets etc sell off their composts to make room for Christmas stuff. You can often pick up bags for about 1/4 of the original price. It's amazing how bags of MPC don't go far when spread on beds and you may need quite a few depending on the sizes you are making.
