How to care for Moth Orchid

sunlight

In nature, Phalaenopsis orchids grow on trees beneath a tropical canopy, receiving bright light softened by leaves. Give yours a bright spot with filtered light rather than intense sun.

Bright indirect light

Place it near an east window, or set it back from a bright south or west window behind a sheer curtain. Too little light usually means few or no flowers, while harsh sun can scorch the leaves.

A bright room is not always bright enough: soft leaf shadows for part of the day are a good sign.

Keep leaves out of hot direct midday sun, especially against glass.

watering

Water thoroughly when the bark is almost dry and the visible roots turn silvery, then let the pot drain completely.

Spring and summer

Check about once a week and expect to water roughly every 5-10 days. Soak the bark until water runs freely from the drainage holes, then empty the outer pot. Bright warmth, small pots, and chunky bark dry faster.

Autumn and winter

In lower light and cooler rooms, watering is often needed roughly every 10-14 days. Check the roots and pot weight first: water when the pot feels light and the mix is nearly dry throughout, not on a fixed calendar.

Clear pots make watering easier: green roots are hydrated, while silvery-gray roots are ready for a drink.

Keep water out of the crown between the leaves and never leave the roots standing in water, as this can cause rot.

humidity

Preferred humidity

50-70%

Phalaenopsis grow as epiphytes in humid tropical forests, so they appreciate moderately moist air with gentle airflow. Most homes are fine at 40-60%, especially if watering is consistent.

Minimum comfort level

Around 40%

Air that stays much drier can cause wrinkled leaves, dry brown tips, and buds that yellow or drop before opening. Winter heating is the usual culprit.

Raise humidity around the plant, not by keeping the pot wet.

Run a small humidifier nearby when indoor air is dry.
Set the pot on a pebble tray with water below the pot base.
Keep it away from heating vents and hot, dry drafts.

Provide airflow if humidity is high, and avoid leaving water in the leaf crown.

temperature

Preferred range

18-27°C (65-80°F)

Winter minimum

16°C (60°F)

Phalaenopsis orchids come from warm, sheltered tropical forests, so they prefer steady indoor warmth. Keep them away from chilly windows in winter and from hot air blowing directly from radiators or vents.

Place it in a room that stays above 16°C (60°F) overnight, and move it back from cold glass after sunset.

Cold drafts or sudden temperature swings can cause buds to yellow and drop.

nutrition

March - September

Feed every 2-4 weeks while new leaves or roots are growing, using a balanced orchid fertilizer at about one-quarter strength. In lower light or when growth slows, reduce to monthly or pause until it resumes.

Nitrogen

Nitrogen supports the broad leaves and new root growth that fuel future flower spikes. A diluted, balanced orchid feed provides enough without pushing soft growth.

Potassium

Potassium supports sturdy growth and flowering. Regular light feeding is more useful than a strong dose before blooming.

Fertilize after watering, then flush the potting mix with plain water about every 1-2 months to prevent salt buildup around the roots.

soil

Chunky, airy orchid mix

Phalaenopsis roots need air as much as moisture, so use a loose mix that drains quickly but holds a little humidity around the roots. A blend of orchid bark with perlite and a small amount of sphagnum moss works well; use finer bark for smaller plants.

pH 5,5 - 6,5

This is slightly acidic, which suits epiphytic orchid roots. Most ready-made orchid mixes fall near this range. Avoid regular potting soil, which stays dense and wet around the roots.

Use a pot with generous drainage holes, and repot when the bark has broken down and starts holding water too long.
