Orchid care

Phalaenopsis

Water
Every 7–10 days
Light
Bright, indirect — no direct sun
Pet safe
Yes — non-toxic to cats & dogs

The moth orchid has a reputation as a diva, but it’s mostly a communication problem: it’s an epiphyte that grows on tree bark, not in soil, so everything you learned about watering potted plants slightly misleads you.

Once you learn to read its roots — silvery means thirsty, green means fine — a phalaenopsis is genuinely easy, and it blooms for months at a stretch.

How often to water a orchid

SeasonFrequencyCue
Spring & summerEvery 7 daysWhen roots look silvery and the bark is dry
Fall & winterEvery 10–14 daysCooler and darker = slower drinking

Run lukewarm water through the bark for a minute (or soak the inner pot for 15 minutes), then drain fully — orchids die from water pooling in the crown and standing in the pot, not from the drink itself. Ice cubes are a marketing gimmick: cold shocks a tropical plant. Roots are your gauge: plump and green after watering, silvery-gray when it’s time again.

Light

Bright, indirect light — an east window is perfect, or a south window filtered by a sheer curtain. Direct midday sun burns the leaves.

Leaf color tells the story: healthy grass-green is right; very dark green means too little light (and no rebloom); reddish or yellowed leaves mean too much.

Common orchid problems

Wrinkled, leathery leaves

Why: Dehydration — underwatering or rotted roots that can’t drink. Fix: Check roots: silvery/firm = water more often; brown/mushy = trim them and repot in fresh bark.

Roots turning brown and mushy

Why: Overwatering or standing water. Fix: Trim dead roots, repot in orchid bark (never soil), always drain after watering.

Blooms dropped — is it dead?

Why: Normal bloom cycle ending. Fix: Not dead. Cut the spike above a node (or at the base), keep caring, and expect a rebloom in months.

Won’t rebloom

Why: Too little light or no night-time temperature drop. Fix: Brighter indirect light, plus a few weeks of cooler nights (~5 °C / 10 °F drop) to trigger a spike.
