Soil preparation for bonsai can present unwelcome obstacles for the hobbyist: individual ingredients can be hard to find and/or too costly in quantities one person would need, and commercial mixes are not always optimal or affordable. And then there'sthe screening process, which is tedious at best and a physical strain at worst. It makes sense, therefore, for regional groups to assist their memberships in this endeavor, harnessing economies of scale and specialized interests for the benefit of all.To this end, as a service to members of the Finger Lakes Bonsai Society (FLBS), located in central New York State, I am providing, at-cost, soil ingredients and mixes. The table below is based on the water retention and drainage measurements appearing in these pages recently, and offers individual ingredients and suggested mixes. Mix prices are generated automatically from a spreadsheet, based on individual ingredient costs.
