Moss Milkshake. Just add water. Grows up to 20 square feet of just the kind of moss you want for your bonsai. Something new We haven’t had a new product for a while now (except for some rare out of print issues of Bonsai Today… not exactly new really), though there is a new Japanese gardening book that’s on its way (stay posted). Field grown bonsai stock… …is coming soon too.
