Phalaenopsis Care Essentials

​

Temperature

​

• Year-Round: Keep the plant warm. Daytime temperatures should be between 70F and 85F, and nighttime temperatures must never drop below 60F.

​

• Flowering Cue: To encourage flower formation, keep the plant cooler (around 60F for 4 to 6 weeks in the autumn.

​

Light

​

• Provide mostly shade light, ideally near an east-facing window.

​

• In summer, ensure it's shaded. In winter, it needs filtered, bright light—avoid direct sun exposure.

 

Water and Humidity

​

• Keep the planting medium moderately moist year-round; it should never dry out completely.

​

• Use soft, lukewarm water. Never water the center (crown) of the plant to prevent rot.

​

• High humidity is essential. Set the pot on a dish filled with moist gravel or stones and spray the leaves often.

​

Fertilizing

​

• Spring/Summer: Use a diluted 20-20-20 fertilizer regularly.

​

• Autumn: Switch to a bloom booster fertilizer combined with cooler nights to trigger bud set.

 

Potting

​

• Roots need plenty of air; avoid waterlogging.

​

• Use a coarse, air- and water-permeable medium like fir bark (medium-grade) mixed with a small amount of peat, charcoal, or perlite.

​​

• Repot every 14 to 18 months into a pot only slightly larger than the previous one. Soak the new potting medium overnight before use.
