New toallotments. Help needed pls

Thanks all. Some grass is just grass. Some has weeds. Not much other waste init. It's couch grass. A friend said I should put it in blk bin bags and tie it up for two weeks. This should sweat it and it should rot away. What do you think? Only half done. 2.5 tonnes waste. Eeek

Couch grass will, in my opinion need more than 2 weeks to cause it to rot and die. There are 4 alternatives, drown it in water for several weeks/months,  leave it bagged in the dark for months, or leave it on the surface to dry in the sun for a few weeks. You can then put it on the compost. The 4th option is as I've said before take it to the tip. Personally I'd go for taking it to the tip as space is precious on the plot and I don't want the hassle of trying to manage a very invasive grass. If you get it wrong you would be back to square one as it would regrow if incorrectly dealt with.

Hello there. My allotment is going great . I have three beds in and now need some help to find out how much top soil I need. Each bed is 2.4x2.4M and the height is .2 M. Can you advise how much soil I need per bed

1.15 surely?

Sorry if I sound daft. Is it 1.15 cm per bed? How many bags of 25 l soil would that be?
