🌱 How to Care for Orchid to Prevent Mealybugs?

💧 How to Water

Water about once a week by soaking the bark medium thoroughly, then let it drain completely. Plump, green or silvery roots are well hydrated; wrinkled, grey roots mean it is time to water again. Avoid letting water pool in the crown.

☀️ Lighting

Place in bright, indirect light such as an east-facing window, out of direct midday sun. Medium green leaves indicate good light; dark green leaves mean too little light, while reddish or yellowish leaves signal too much direct sun.

🪴 Ideal Soil

Pot in a coarse, bark-based orchid mix, never regular potting soil, inside a container with excellent drainage or a slotted orchid pot so roots can breathe. Refresh the medium every one to two years as it breaks down and becomes compact.
