This is best done about the end of September. Water only sparingly, only enough to keep the leaves from shriveling. This is a rest period for the plant and is necessary to set buds. Soil for the Christmas Cactus is a bit richer than that for ordinary cacti. Avoid over-feeding and do not continue to feed all year as this may result in blind plants.
Temperatures are too high or humidity too low plants grown too soft during the summer.
Plants not properly rested, spring and summer care neglected plants exposed to very high temperatures for long periods of time. Too dry, too much sunlight. Low humidity, too much water resulting in root rot. Plants may be forced or held back but without the proper facilities such as a greenhouse you may be jeopardizing blooming altogether. All are treated in the same manner.
