How often to water Moth orchid
- Spring–Summer (Mar–Sep)
- Every 7 days
- Water generously with lukewarm water only once the moss or bark has dried right through, about every seven to ten days in the growing season.
- Autumn (Oct–Nov)
- Every 10 days
- As it cools the medium dries slowly, so wait a few extra days after it dries, roughly every ten days.
- Winter (Dec–Feb)
- Every 14 days
- In the cold months the roots take up little water, so about every two to three weeks on a mild morning is the guide, keeping water out of the crown.
Light and placement for Moth orchid
A bright window behind a sheer curtain is the guide; direct sun scorches the leaves, deep shade stops flower spikes, and air-conditioner drafts should be avoided.
Overwintering Moth orchid
Overwintering guide: 10°C (50°F) or above
Cold-sensitive: keep it indoors above about 10°C, ideally 15°C, moving it away from the window at night and watering less; around 18°C it sets spikes more readily.
Fertilizing and repotting Moth orchid
Fertilizer
From May to September, when new leaves and roots grow, give liquid feed diluted weaker than the label about every two weeks; none while in bloom or in winter.
When to repot
Spring–Summer (Mar–Sep)
Common problems with Moth orchid
- Left in the gift arrangement and watered on, the roots rot.
- Cold at a winter window yellows the leaves and damages the plant.
- Direct sun scorches the leaves, leaving dark patches.
Tips for growing Moth orchid
- After flowering, separate the plants into their own pots with fresh moss.
- Cutting the spent spike at the base lets the plant rest and bloom well next year.
- Wiping water out of the leaf axils prevents rot.
These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
