Bought some Wickes new formula compost when it was reduced to £3. (now gone back to 4 for £15) Potted on some seedlings.
Put half in Wickes compost and they have clearly done better in only a couple of weeks. Rather ended up wishing I had used it for all of them.
It has a rather odd feel. A bit like rubbish from the vacuum cleaner, but the plants seem to like it.
