As the plant approaches its blooming cycle in the fall, reduce or stop fertilization. This encourages the plant to focus its energy on bud formation rather than leaf growth. Once blooms appear, you can resume light fertilization to support flower development.
7. Try the Viral ‘Dark Closet’ Hack—The Right Way
The ‘dark closet’ hack involves placing your Christmas cactus in a dark closet for 12 to 14 hours a day for several weeks to simulate the natural reduction in daylight hours. This method can effectively trigger blooming if done correctly.
Ensure that the closet or dark space is free from any light sources, as even a small amount of light can disrupt the bloom cycle. Be consistent with the timing, and once buds appear, gradually reintroduce the plant to brighter conditions to encourage full blooming.
8. Give Your Plant a Summer Vacation Outdoors
Taking your Christmas cactus outdoors during the summer can help it thrive and prepare for a successful blooming season. Place the plant in a shaded area where it receives indirect sunlight, as direct sunlight can scorch its leaves.
The outdoor environment provides natural fluctuations in temperature and humidity, which can strengthen the plant and promote healthy growth. Be sure to bring the plant back indoors before temperatures drop below 50°F (10°C) to prevent damage.
