Water
While cacti are drought-tolerant, the rabbit ear cactus still requires some water to maintain moisture balance. Water the plant once a week, providing approximately 30-40ml of water each time, to avoid waterlogging.
Light
As a desert plant, the rabbit ear cactus thrives in direct sunlight. If grown indoors or in shaded areas, ensure it receives ample sunlight by placing it near a window or taking it outside for sunbathing 2-3 times a week.
Temperature
The rabbit ear cactus can withstand temperatures ranging from 10°C to 50°C, but it grows optimally between 15°C and 28°C. Extreme temperatures can be detrimental to its health.
Pest and Disease Control
Common issues with the rabbit ear cactus include root rot, anthracnose, and mealybugs. Root rot is characterized by dark spots in black, gray, red, purple, or white colors. It is often caused by improper branch cutting techniques. To prevent this, sterilize cutting tools and use soil and fertilizer with minimal mold content. Remove any infected branches to prevent the spread of the disease.
Anthracnose, indicated by watery brown spots, usually occurs during the summer and early winter. Keep the plant in a dry and well-ventilated area, and reduce watering. Mealybugs, which suck the plant’s sap, can be controlled by regular inspections, manual removal, and the use of insecticides.
Propagation
Propagation through branch cutting is typically done in the spring. Choose healthy, robust branches and cut them cleanly. Allow the cuts to dry and scab over before planting them in prepared pots. Ensure the cuttings are firmly planted, and within 20-25 days, they should develop roots. Place the newly propagated cacti in a shaded area with good airflow, ideally at a temperature of 25°C.
5 Where to Buy and Price Range
