1 Apply an organic fungicide to the affected leaves to eliminate the fungal spores and prevent further spread.
2 Improve air circulation around the orchid by using a small fan and ensure the plant is not in an area with stagnant, high humidity.
3 Repot the orchid in a fresh, well-draining medium like orchid bark to reduce the risk of re-infection from contaminated substrate.

Mealybug Infestation

Small, white, cottony-looking insects that congregate in the crevices of the orchid's leaves and flower spikes, secreting honeydew.

Very Common

1 Isolate the orchid immediately to prevent the mealybugs from spreading to other plants in your collection.
2 Treat the infestation by spraying the plant with an organic insecticide/miticide to kill the insects and their eggs.
3 Gently wipe away visible white cottony clusters from leaf crevices and flower spikes using a cotton swab dipped in alcohol.

Mineral/Salt Buildup

Excessive fertilization or hard water can leave white, crusty deposits on the leaf surfaces or at the edges of the pot.

Common

Botrytis (Gray Mold) - Early Stage

In the early stages of infection in high-humidity environments, fungal spores can appear as light, dusty patches before turning into dark rot.

Common

How to confirm: Check if the white areas are accompanied by soft, brownish, decaying tissue on the flower petals or leaf tips.

1 Remove and discard any heavily infected leaves or flowers immediately to prevent the mold from spreading to healthy tissue.
2 Apply an organic fungicide to the affected areas to halt fungal growth and protect the remaining plant tissue.
3 Improve air circulation around the orchid and reduce humidity levels to create an environment less hospitable to Botrytis spores.
