This is the compost mix we currently use on the nursery. We have been growing succulents for around twenty years commercially and have kept adjusting the mix to get the right mix for the plants we grow. This is a reduced peat mix that is suitable for most if not all succulents. It will contain reduced peat compost, perlite as well as a vine weevil control chemical and a slow release fertilizer.
It will be supplied in a grip seal bag so you can use a little as needed then resealed to keep fresh and to also stop the compost from drying out too much.
The bag will contain between 2 and 3Lt of compost.
