glassortwo I've bought some Yellow Rattle, which is supposed to weaken the grass and so the wildflower plants will have more chance to take hold. Probably best to just do a patch at a time. Just be careful for any other seed to go onto the patch you are working on if you don't want that seed to be there. Carol Klein does a lot of taking cuttings, propagating etc. Maybe look at some of her work on youtube. It could save you a small fortune. I hope you have lots of fun and pleasure doing it. PM me if you want, it is an interest of mine. X
