The plants may be repotted in September, and if they have rooted well, and are healthy, a size larger pot will be required. It is wise to have the fresh pots ready washed and drained, and the compost prepared in advance; then the potting is quickly performed. As each plant is turned out, the old soil should be carefully worked away from the roots with a blunt stick, and the roots examined. Any decaying ones should be cut away, and the others carefully coiled in the new pots. The fresh soil should then be filled in and made firm by steady, gentle pressure. In the case of plants which have reached their pot limit, they may be turned out, the drainage examined and put right if defective, and sufficient soil carefully removed from the outsides of the old ball to admit of a top-dressing of fresh soil when the plant is put back.
