🌱 How to Care for Prickly Pear to Prevent Aphids?

💧 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.

☀️ 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.

🪴 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.
