Why Alstroemeria Goes Dormant in Summer Heat and How to Revive It

Alstroemeria (Peruvian lily) blooms nonstop through Christmas in warm climates, then disappears completely when summer heat arrives.

Natural Cycle

• Heat-induced dormancy: foliage dies back, plant retreats to underground tubers.
• Returns when temperatures cool in fall.

What to Do

• Don’t panic—it’s not dead.
• Reduce watering during dormancy.
• Mark the spot to avoid accidental digging.
• Expect regrowth in autumn.

This is normal for Alstroemeria in hot climates. Enjoy the cool-season show!
