Our popular Akadama, Kanuma and Kiryuzuna are authentic products imported from Japan and made especially for Bonsai. 

Akadama and Kanuma are traditional Japanese bonsai growing media valued primarily for their drainage, moisture retention, and root-growing properties. Their natural colours and textures also contribute to the refined aesthetic traditionally associated with Japanese bonsai.

Debco Bonsai is a professionally formulated option that's great for people who want an easy, ready-to-use growing solution. This is the convenient option for customers who don't want to formulate their own substrate.

Components for Custom Mixes: Products like Scoria, Maifan Stone, Hydro Balls and Ecopore perlite can be mixed with other media to alter drainage, aeration, moisture retention, and weight. They allow experienced growers to tailor a substrate to their particular bonsai, climate and watering habits. See below for Frequently Asked Questions:
