For those who want to repot their outdoor evergreen bonsai, there is no substitute for having just the right type of soil mix. This gives more drainage than deciduous soil as more grit is added in this mix.
This mix is our tried and tested soil mix for all species of evergreen trees.
Peter and the team at Herons have spent, and continue to spend a lot of time developing this bonsai compost. It is a tried and tested recipe and well suited to our British growing conditions, it drains well but retains moisture.
