Likely causes
Aphid Infestation
Most likelyHow to tell: You see tiny green or black insects clustering on new growth or flower buds. You might also notice a sticky residue called honeydew on the leaves.
What to do: Gently wash the aphids off with a soft stream of lukewarm water. If they persist, wipe the leaves with a cotton swab dipped in mild soapy water.
Poor Air Circulation
PossibleHow to tell: The plant is in a stagnant corner where pests can easily settle and multiply.
What to do: Move your orchid to a spot with gentle, indirect air movement. Avoid placing it directly in front of a fan or heater.
When to worry
A few aphids are manageable, but a heavy infestation can cause buds to drop and leaves to yellow. Treat them as soon as you spot the first one.
Stopping it coming back
Inspect your plant weekly during your watering routine. Keeping the leaves clean and the environment airy helps deter pests.
