Over the years we have had problems when trying to get a compost made by the big compost suppliers to our specific requirements for the Protea we grow. So we ended up making our own. This is the Protea compost used by us on the nursery. It has been modified over the years and works very well when pot growing Proteacea. The grip seal bag can be resealed if you want to so you only need to take what you want and then reseal to keep the rest as fresh as possible. Each bag contains approximately 3Lt of mix.
