Seedling
2-3 weeksTiny seedlings emerge within 7-10 days with delicate true leaves. Very small and fragile initially.
Keep soil moist under bright indirect light. Maintain 70-75°F. Provide gentle air circulation. Avoid damping off by ensuring good drainage.
Vegetative
2-3 weeksPlant develops branching stems and abundant foliage. Growth is rapid and sprawling. No flowers present yet.
Pinch tips once or twice to encourage bushier growth. Provide full sun exposure. Fertilize every 2 weeks with balanced fertilizer. Support with stakes if needed.
Flowering
Until frost (4+ months in warm climates)Plant produces abundant small trumpet-shaped coral-pink flowers covering most of the foliage. Cascading growth becomes pronounced.
Fertilize weekly with bloom-promoting fertilizer (higher phosphorus). Deadheading is optional but extends bloom. Water consistently. Monitor for pests.
Peak Production
2-3 months or longerPlant is fully covered with continuous flowering, trails extensively, and foliage remains healthy and vibrant.
Maintain regular watering and fertilizing schedule. Watch for aphids or spider mites. Prune back if becoming too leggy (optional).
Decline
Variable; depends on first frost dateIn fall/cooler weather, blooming slows as temperatures drop below 50°F. Plant becomes dormant or frost-killed in colder zones.
Continue watering as soil dries. In warm climates (zones 9-11), plant can overwinter. In cooler zones, treat as annual and compost spent plants.
