Using builders' dumpy bags, for composting and leaf mould

[wbmkk]

What’s the best way to use builders; dumpy bags, for making compost and for leaf mould?

I managed to get hold of 4 'dumpy bags' today ... those big bags, which builders get sand and stone delivered in.

Bag 1 .. Compost Heap

I assume I would cut the bottom out of the bottom and place the bag on the ground. Is this correct ?
Do I need to put holes in the sides too ?
What layer should I put in first, so there is some air movement ?

Bag 2 etc … Leafmould

Do I need to cut the bottom off these bags too ?
What about side holes ?
Do I leave the top open, to let rainwater in, or close it off

thank you for any advice provided.

ps I can't go to the allotment this morning until I get a couple of answers here , so please don't be in too much of a hurry.

I think those bags are woven plastic so full of holes anyway, often the sand they contain is wet and has to drain. If i was to cut a hole in the bottom I think i would put some concrete blocks in the bottom to stop it lifting and having the compost come out of the bottom (specialy when you try to turn it. If you cut holes in the sides (which i dont think you need) melt them with a hot piece of bar or it will fray into larger holes. I already do this for leaves and dont bother cutting a holes in for that because leaves compost a lot slower, but i would cut a hole in the bottom for general compost to let worms in.
Now get back to worl lol.

I have used them as they were, didnt cut the bottoms off, but drove posts in at the corners to support then. Worked well but a bit difficult to empty. The worms seemed to find their way in without any problems.

Ditto as above, really. Very useful things to have, as they keep 'stuff' tidy! personally, I would stack my fallen leaves inside in black sacks. They rot really well in those if the bags are stabbed with a fork when filled. I emptied a bag this week that had been stored over a year, and it was nearly all ready to use as compost.

I grew some tatties in some this year.....bit of compost in the botgom then kept filling ghem up with leaves. Decent crop and the leaves rotted down nicely at the same time
