| A Christmas cactus (A Thanksgiving cactus) |
In truth, getting a Thanksgiving cactus to bloom is easier than getting desert cacti to flower indoor. The "green crab" doesn't need direct sunlight and doesn't demand dry wintering in a cool room in contrast to its desert "kin". However sometimes a Christmas cactus doesn't want to bloom. Our green friend has a few reasons for that:
1. The plant is too young. If you grow Schlumbergera from a cutting, you ought to know that the cactus is able to bloom in 2-3 years (sometimes in 4-5 years!) after the rooting.

2. A dark place. The plant isn't able to bloom if it grows in the shade. A Christmas cactus needs bright diffuse light.
3. Lack of rest period. Schlumbergera needs short rest period when daylight hours shorten. In October/November we ought to diminish frequency of the plant watering. Also in this period we ought to locate the cactus in a room having temperature 59-64 degrees Fahrenheit (15-18 degrees Celsius). In other months this green person prefers room temperature.

4. Transposition. We shouldn't move a Christmas cactus when the budding starts or else the plant may shed the buds.
5. Dry air. Also the plant shed the buds and the flowers if air is dry. The "December cactus" adores humid air and likes spraying.
5. Soil depletion. The cactus may refuse to bloom if the soil is emaciated. In this case, please, transplant the houseplant. Thanksgiving cacti like mellow soil.
6. Over-watering. Another reason of a Thanksgiving cactus unblooming is over-watering. Of course, we should water this plant more frequent than desert cactuses. Nevertheless a bog in the pot is inadmissible. We must water the plant when a topsoil is dry. Also over-watering of the cactus produces abscission the segments of stems.
