Growth Stages

1

Seedling/Cutting Establishment

4-6 weeks

Young plants with tender green leaves emerging from soil or rooting medium. Vine develops initial structure and root system.

Keep soil moist but not soggy. Provide bright, indirect light. Protect from strong winds. Maintain temperatures above 60°F.

2

Vegetative Growth

8-12 weeks

Vigorous vine growth with lush green foliage. Plant develops multiple stems and begins climbing/spreading along support structure.

Fertilize every 2 weeks with balanced fertilizer or one higher in nitrogen. Provide sturdy trellis or support. Prune to encourage bushier growth if desired.

3

Pre-flowering

4-8 weeks

Vine matures and produces flower buds along stems. Small terminal clusters appear at branch tips.

Switch to lower-nitrogen fertilizer (higher phosphorus and potassium) to encourage blooming. Maintain consistent moisture. Ensure adequate light.

4

Flowering

8+ weeks (continuous in zones 10-12)

Abundant small, white, star-shaped flowers bloom in clusters. Flowers are highly fragrant, especially in evening. Blooms appear continuously in warm climates.

Continue regular watering and humidity. Deadhead spent flowers to encourage continued blooming. Avoid excessive pruning during this stage. Maintain warm temperatures.

5

Seed Development/Dormancy

Variable; minimal dormancy in tropical zones

Flowers fade and small seed pods may develop. In very warm climates, flowering continues; in cooler areas or indoors, growth may slow.

Reduce watering slightly if growth slows. Continue fertilizing if blooming persists. Remove seed pods if you prefer plants focus energy on growth rather than seed production.
