Bonsai Focus Repotting Mix is designed for best results with the widest range of bonsai trees. It contains coir, composted fine bark, grit and sand.
Young bonsai trees need repotting every year. Older and slow-growing bonsai will need repotting when they are out-growing their pot or the condition of the old growing medium is poor. For best results, plants should be re-potted early in the year just before the new spring growth starts, but they can be re-potted at any time in the summer.
