Seedling
2-3 weeksTiny cotyledons emerge and develop first true leaves within 1-2 weeks
Keep soil consistently moist but not soggy; provide bright indirect light. Maintain temperatures around 70-75°F. Thin seedlings if overcrowded.
Vegetative Growth
3-4 weeksPlant develops multiple stems and foliage with increasing branching; stems begin trailing
Provide full sun and maintain regular watering. Fertilize weekly with balanced fertilizer (10-10-10). Pinch back early growth if desired to encourage bushiness, though trailing varieties naturally cascade.
Flowering Initiation
1-2 weeksFirst flower buds appear at branch tips as plant matures
Switch to a higher-phosphorus fertilizer (10-20-10) to encourage blooming. Maintain consistent moisture and full sun exposure. Remove any diseased foliage.
Prolific Flowering
8-12 weeks (spring through fall)Abundant small yellow trumpet flowers cover the plant continuously; stems trail 12-18 inches or more
Deadheading is rarely necessary as self-cleaning is excellent. Continue regular watering and feeding every 1-2 weeks with bloom-boosting fertilizer. Watch for pests and diseases.
Decline (Fall/Winter)
8+ weeks until frost or season's endFlowering slows as days shorten and temperatures drop; foliage may become less vigorous
In zones 9-11 where plant may overwinter, reduce watering and fertilizing. In cooler zones, treat as annual and remove spent plants after frost, or bring indoors if desired.
