I’m well aware of the current trend of peat-free growing. I use Dalefoot compost
I have been using it for a few years and I’m very happy with it. They have improved it by adding comfrey to it, there is a range of different kinds, depending what you want to use it for – seed propagation, potting up and, best of all, tomato compost. My tomato plants are the proof of that.
The compost is a bit more expensive than the usual product you get in a garden centre but it is well worth the cost.
