What to do if your Christmas cactus won't bloom? A few tips to encourage flowering

The Christmas cactus (Schlumbergera) is a particularly beautiful plant, and many flower lovers have one at home. But some have found that their Christmas cactus barely blooms after repotting, so do you know how to encourage a Christmas cactus to bloom?

The best time to repot a Christmas cactus is in spring. If you repot it in autumn, its flowering that year will be affected.

In summer the temperature is relatively high, so it is not suitable for repotting a Christmas cactus. In winter the temperature is relatively low, but if your Christmas cactus is kept in a greenhouse, repotting can be done.

If you find that the flowers your Christmas cactus produces are not vibrant, after the flowers fade you can cut off all the spent flowers and repot it with the soil ball intact, taking care to avoid injuring the roots.

The pot used for repotting should be larger than the original one, and ideally a clay pot or a red terracotta pot, as they have better porosity and drainage, which benefits its growth.

If you want to take cuttings, after the Christmas cactus flowers fade, cut off its robust stems and root them in water. Keep them in a well-ventilated, shaded spot, and roots will soon appear.

For the first two or three weeks after repotting, be careful not to let it get any sunlight. Keep it in a ventilated, shaded place, and then gradually let it adapt to light.

The Christmas cactus itself is a short-day plant, so by adjusting its light hours you can adjust its flowering period. When summer temperatures are high, avoid direct sunlight.

When autumn comes, you should encourage flowering by adjusting its light hours. Once the weather turns cool, cover the Christmas cactus at night with a black plastic bag or something else that blocks light, then uncover it after twelve hours; this can promote its flowering.

At the same time, be sure to maintain a certain temperature difference for it: the daytime care temperature should be between 12 and 18 degrees, and the nighttime temperature between 9 and 12 degrees. This temperature difference is most suitable for its flowering.

Spraying monopotassium phosphate on its leaves every two or three weeks or so can also promote its flowering. At the same time, keep it moist and do not let the potting soil dry out, but also do not overwater.
