This is the PERFECT time to repot your temperate bonsai! Those are the trees that require a winter dormancy (tropicals get repotted in summer). Once the buds break and the leaves are out, it’s too late. You’ll want to use a fast-draining water-retentive mix specifically designed for bonsai. We have multiple soil mixes available at the nursery, as well as ingredients if you prefer to make your own. Our March 2015 class is currently sold-out, so if you have questions about repotting, please ask!
