that it provides a bonsai (or any plant for that matter). Be confident that

switching to inorganic soils is widely considered 'best practice'. Bonsai grown in
an inorganic soil do not need any special fertilising regime or special ingredients
to keep them healthy. There are of course some differences between compost-
based organic mixes and inorganic mixes. Inorganic soils contain little or no
nutrients, however, compost/peat based organic soils just as equally only provide
very limited nutrients to a bonsai and these are quickly depleted within a bonsai
pot. Organics are able to retain more nutrients better than inorganic's (after
feeding) but this is not necessarily a good thing. Trees growing in inorganics
need (but can also take without any danger of root burn) more fertiliser than
those growing in an organic soil. Many enthusiasts see this as being
advantageous though as it allows the enthusiast to feed their bonsai heavily to
encourage better growth, health and faster development. That an organic bonsai
soil can hold nutrients for a little longer than an inorganic bonsai soil is hardly
advantageous as bonsai growing in organic soils still need to be fed regularly!
With my inorganic soil mix, I am able to feed heavily and use a slow release
fertiliser and a fortnightly full strength balanced plant fertiliser simultaneously

throughout the growing season.
