Why Your Peruvian Lily (Alstroemeria) Isn't Blooming

Your 'Oxana' Alstroemeria (Princess Lily) bloomed once, then stopped. Two common issues explain why—and both are fixable.

1. Missing Dormancy (Cold Period)

Alstroemerias are native to the Andes. They need a cool, dormant period (40–50°F for 8–12 weeks) to initiate flower buds. As a houseplant in constant warmth, it never gets this signal.

Fix: In fall, move pot to an unheated garage, basement, or cool porch (above freezing). Keep barely moist. Return to warmth in late winter.

2. Root-Bound in Pot

After 3+ years, the rhizomes fill the pot, exhausting soil and limiting water/nutrient uptake.

Fix: In early spring, remove plant; gently separate rhizomes (they're brittle). Replant divisions in fresh, rich potting mix—one per pot or 2–3 in a larger container.

Ongoing Care for Blooms

• Light: Full sun to part shade (south/east window).
• Water: Keep evenly moist; don't let dry out completely.
• Fertilizer: Balanced liquid (10-10-10) monthly during growth; stop in dormancy.
• Hardiness: Zone 7+ outdoors with mulch. In colder zones, store dormant in cool (35–45°F), dark place.

With a winter chill and room to grow, your Alstroemeria should reward you with months of exotic blooms.
