After being to the plot this morning and taking off the plastic on bed 1 the grass had indeed died leaving behind the couch grass , i raked all I could see into a pile and took it off . I then covered the whole bed with about 50- 75 mm of multi purpose compost and it looks great. Next I need to get some weed fabric which will look a lot better than the plastic and also allow water through, I will put this on next weekend.
The other beds are looking great and apart from one half bed are all ready for planting up.
The half bed still needs some attention and a layer of compost then I’m done👍
