Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings emerge with true leaves appearing after cotyledons; growth is slow initially

Provide bright light, maintain consistent moisture without waterlogging, maintain temperature around 65-70°F, thin seedlings to prevent damping-off

2

Vegetative Growth

3-4 weeks

Plant develops trailing stems with small, narrow opposite leaves; no flowers yet

Pinch back growing tips to encourage bushiness, gradually acclimate to outdoor conditions, apply balanced fertilizer every 2 weeks

3

Flowering

8-12 weeks or until frost

Abundant small snapdragon-like flowers in coral, pink, orange, and bi-color patterns appear along trailing stems; flowering accelerates in warm weather

Deadhead spent flowers to prolong blooming, maintain consistent watering, apply balanced or slightly higher phosphorus fertilizer weekly, ensure full sun exposure

4

Peak Production

4-8 weeks

Plant reaches full cascading habit completely covered in continuous blooms; stems trail 12-18 inches

Maintain regular deadheading, water deeply when soil surface dries, monitor for pests, reduce fertility if plant becomes too vegetative

5

Decline/Dormancy

Variable

Flowering slows in cold weather or intense heat; plant may decline in frost-prone areas

In zones 9b and warmer, reduce watering and allow period of rest, cut back by one-third in late fall, or dig up and overwinter indoors in cooler zones
