ðą How to Care for Orchid Cactus to Prevent Aphids?
ð§ How to Water
Water when the top third of the soil is dry â roughly every 7â14 days in spring and summer. In winter, reduce to once every 3â4 weeks. Never let the pot sit in standing water; root rot is the most common problem.
âïļ Lighting
Provide bright indirect light, ideally near an east- or north-facing window with a sheer curtain. Avoid direct afternoon sun, which scorches the flat stems. Insufficient light results in weak, leggy growth and no flowers.
ðŠī Ideal Soil
Use a light, well-draining mix: combine 2 parts cactus soil with 1 part orchid bark or perlite. Aim for a pH of 5.5â6.5. Avoid heavy potting mixes that retain too much moisture.
