🌱 How to Care for Giant orchid (Grammatophyllum) to Prevent Mealybugs?

💧 How to Water

During the growing season water generously, especially when flower spikes are emerging, usually every 3-5 days, letting the mix approach dryness before the next watering. Keep it a little drier in winter. Water in the morning so the leaves dry before night, and never leave the pot standing in water. Brown, shrivelled leaf tips mean it is too dry.

☀️ Lighting

It likes strong light, similar to a Cattleya: morning sun is ideal, but direct midday sun burns the leaves. Indoors, use an east window or a very bright window with a sheer curtain. Lime-green leaves show the right light; dark green means too little, yellowing means too much. Without enough light and heat it will not flower.

🪴 Ideal Soil

Use a very coarse, airy mix: large-grade fir bark, charcoal, lava rock or a blend of these; sphagnum moss also works for young plants. Mature plants do best in wooden baskets or large pots with plenty of drainage. Repot every 2 years in spring, into a container with room for 2-3 years of growth.
