Best Sphagnum Moss for Bonsai
As an Amazon Associate I earn from qualifying purchases.
Sphagnum moss is the exception to the inorganic rule, and it earns that exception. Long-fibre sphagnum holds a great deal of water while staying airy, which is exactly what an air layer, a struggling root system or a batch of cuttings needs. It is a temporary tool rather than a soil. What varies is fibre length, how much stick and grit is mixed in, and whether the moss is milled, compressed or sold loose. We weighed fibre length first, since long strands wrap a layer neatly and short milled moss turns to mush. Cleanliness came next, because twigs and soil in the bale mean sorting time at the bench. Long-fibre grades suit air layering and top dressing over weak roots. Milled or chopped moss suits seed trays, and blending into a recovery mix for collected trees that need extra moisture.
