The Christmas cactus, with its brightly colored flowers ranging from pink to white, red to purple, is one of the most loved plants during the holidays. But not everyone knows that, to stimulate winter flowering, it is essential to keep it in just one place in the house and respect some precise precautions.
According to the Royal Horticultural Society (RHS), this plant is simple to grow but requires two “rest” periods per year to ensure abundant flowering. Experts explain:
The Christmas cactus is easy to care for, but to obtain flowering it must be given two resting phases, one before the formation of buds in autumn and the other after flowering, between late winter and early spring.
The secret is the temperature
During growth, in spring and summer, the Christmas cactus prefers warm temperatures, between 18 and 20 °C. The same applies in the flowering period, from late November to early January. It is important to place it in a warm spot in the house but away from direct heat sources such as radiators or stoves.
To stimulate the formation of buds, however, two cooler periods are needed, with temperatures between 12 and 15 °C. One of these should take place before flowering, the other after, between the end of January and March.
The RHS specifies that it is not necessary to be too rigorous with the degrees: what matters is to create a slight thermal drop compared to usual temperatures.
Pay attention to watering
In addition to the cold, water also plays a fundamental role. The Christmas cactus needs two rest periods with reduced watering.
From April to September the soil must remain moist but never soaked. Starting from mid-September, and until the buds appear, it is best to gradually reduce the water. When the flowers start to bloom, you can start watering regularly again, avoiding stagnation.
After flowering, between the end of January and the end of March, the cactus enters the second phase of rest: in this period the upper layer of soil must dry out slightly between one watering and another, without however leaving it completely dry.
Where to place it
The position is decisive: once the ideal spot has been chosen – bright but not exposed to direct sun – the cactus should no longer be moved. Changes in light or temperature can compromise the formation of buds and cause already developed flowers to fall.
By following these simple rules, the Christmas cactus will be able to provide a cascade of flowers in the colder months, bringing a touch of color and joy during the holidays.
