small packs of grit for rose cuttings?
Does anyone know where I can get a very small (not over 1 kg max) bag of grit (or something similar to mix with normal compost)? It's to make cuttings of a couple of very old and much loved roses.
I really don't want to buy a lot as I won't be gardening here for long - planning my escape before the Brexit disaster kicks in! If I can't get a small bag of something I guess I'll just go with normal compost.
