Orchids 101: Moth Orchid (Phalaenopsis) Care & Reblooming

Phalaenopsis—the moth orchid—is familiar from grocery, home improvement, and flower shops. Great starter orchid. Decorative: winter/spring blooms (rare in houseplants), unusual grace with arching stalks. Not too large, fit tight spots; miniatures available. Advantage: in bloom, place anywhere. Only out of bloom are they light-fussy.

The New York Botanical Garden: Many succumb to store phalaenopsis or receive as gifts. Low cost leads to treating as long-lasting cut flowers. But no need to discard post-bloom—most reward with years of blooms.

The New York Botanical Garden: Wide color/size range—miniatures rising in popularity.

St Charles: Shade-tolerant. North/east window in bright room; keep out of direct sun.

Renaissance Development Corporation: Happy at 70–80°F (21–27°C) day, ~60°F (16°C) night; tolerate 95°F (35°C) occasionally.

Need more humidity than people like. Pebble tray (pot above water) or morning misting.

P2 Design: Water morning when roots silver, medium barely damp, pot light. Room-temp water. Drain thoroughly—damp, not soaked.

Rough Linen: Feed ~¼-strength liquid fertilizer weekly; cut back in bloom. Repot when mix breaks down (1–3 years). Orchid mix/bark best.

Note: Roots atop mix = aerial roots. Normal for air plants.

The New York Botanical Garden: To rebloom: snip flower spike after bloom (under first bloom or at base). Wait for second spike. No rebloom? Ensure night temp drops to ~50°F (10°C).
