Call for a ban on peat in garden compost

As both Veggie and TMTT has said the quality of reasonable priced peat free compost is very poor, ...

TMTT didn't say that, what he did say was "In my opinion the updated New Horizon formula is much better and seems similar in composition to Melcourt..." He did say other people were still complaining but that could be because of prejudice after their first contact with the stuff.
If peat was banned, then, if the quality was still dire, may be buyers would protest and get something done as they would not have an alternative product.

I came across Melcourt SylvGrow brand at Bluebell cottages not far from here where Sue Beesley has a plant nursery. She grows all her plants and seedlings peat free. The only problem with it is that you have to be careful watering as the surface dries but it can stay quite damp lower down. If she can run her business using no peat, then maybe we should make the effort also? There are more and more people understanding we have only one planet and it is round, not flat so resources are finite..
