ðą How to Care for Prickly Pear to Prevent Mealybugs?
ð§ How to Water
Water only when the substrate is completely dry, usually every 10-14 days during spring and summer. In winter, drastically reduce or suspend watering, as the plant enters dormancy and excess moisture is the primary cause of rot.
âïļ Lighting
Prefers full, direct sun for at least 6 hours daily. Indoors, place it near the sunniest window in the house; low light causes etiolation (weak, elongated growth) of the pads.
ðŠī Ideal Soil
Use a fast-draining mineral substrate, with 70-80% inert material (coarse sand, pumice, or perlite) and the remainder organic matter. Ideally, the substrate should dry within 1 to 3 days after watering.
