🌱 How to Care for Harrison's Bifrenaria to Prevent Scale Insects?

💧 How to Water

Water every 7 days during the growing season (spring–summer), allowing the substrate to dry slightly between waterings. During winter dormancy, reduce watering to once a month and stop fertilizing completely until new growth emerges in spring.

☀️ Lighting

Provide bright indirect light — ideally 4 to 6 hours of morning sun with afternoon shade. A 40–50% shade cloth is ideal. Good light is essential for blooming, but direct afternoon sun can scorch the leaves.

🪴 Ideal Soil

Use a coarse, well-draining orchid mix: equal parts pine bark, horticultural charcoal, and perlite or grit. The medium must allow excellent root aeration. Unglazed clay pots or wooden baskets are preferred.
