Schlumbergera gaertneri, formerly Hatiora gaertneri, is a species of epiphytic cactus which belongs to the tribe Rhipsalideae within the subfamily Cactoideae of the Cactaceae. Together with the hybrid with S. rosea, Schlumbergera × graeseri, it is known as Easter cactus or Whitsun cactus and is a widely cultivated ornamental plant. It has received the Royal Horticultural Society's Award of Garden Merit.
Easter cactus has strong resistance to disease and generally remains healthy under typical care conditions. That said, it can be vulnerable to mealybugs; these pests may cause some harm but are usually not a major danger. Regarding care, Easter cactus tolerates drought and does not require frequent watering. It can go long stretches without water and needs little fertilizer. However, if it receives poor light and is watered too much, it is very prone to root rot. In general, Easter cactus is a good choice for those who prefer low-maintenance plants, though it is still important to know and follow its basic needs. It is especially appropriate for people who are away for extended periods and might forget to water regularly.
How to keep Schlumbergera Gaertneri.
Light
Easter cactus grows best with moderate sunlight and can tolerate darker conditions when necessary. Its growth may falter if exposed to excessive sunlight or very low light.
Humidity
This plant will thrive in moderate humidity, which is probably the level in your home. However, misting it a few times a week can be very beneficial. Make sure the room has good ventilation.
Temperature
In its native habitat, easter cactus grows in tropical forests with humid conditions and temperatures that remain between 20 and 30 ℃ (68 to 86 ℉). This indicates that it needs a warm, humid setting for proper growth. Easter cactus prefers temperatures from 20 to 38 ℃ (68 to 100 ℉), which makes it a good indoor plant. In the cooler months, however, it should be kept in a cooler but still comfortable range of 15 to 18 ℃ (59 to 64 ℉) to allow it to rest.
Fertilizer
For an Easter cactus, light applications of fertilizer once or twice a year during the growing season are enough. Do not fertilize in winter or summer when the plant is dormant. Reduce the amount of fertilizer for repotted specimens and wait a couple of months after repotting before applying fertilizer. Feeding helps maintain healthy growth and promotes flowering.
Pot & Repot
Repot an Easter cactus in spring or summer, selecting a pot slightly larger than the current one that provides good drainage. Use a well-draining, sandy or gritty cactus mix. Handle it carefully to avoid the spines. Allow the cactus to dry out before repotting to prevent root rot. After repotting, wait for a week before watering so the roots can heal.
