I have a lot of pots, some contain plants that fare better with John Innes No. 2 apparently, so have some of that left.
The others have been happy with Jack's Magic. I am aware that compost has changed (peat) and the new lot is different, not opened it yet, it is also not available where I usually get it.
I have sand should I need it so usually mix it in.
What is a good general purpose compost please? (Preferably one that is readily available).
