Growth Stages

1

Seedling

3-4 weeks

Tiny green shoots emerge with cotyledons; delicate true leaves develop

Maintain warm temperatures (70-80°F), consistent moisture, and bright indirect light; protect from direct sun; keep humidity high

2

Vegetative Growth

4-8 weeks

Plant develops multiple stems and leaves; bushy growth habit forms

Pinch growing tips to encourage branching; provide full sun; fertilize every 2 weeks with balanced fertilizer; maintain warm conditions

3

Pre-flowering

3-4 weeks

Plant reaches mature size; flower buds begin to form at stem tips

Switch to lower nitrogen, higher phosphorus fertilizer to promote blooming; ensure consistent moisture and humidity; reduce watering slightly if needed to encourage flowering

4

Flowering

8-12 weeks or longer

Dense panicles of tubular red, orange, or coral flowers bloom profusely; flowers attract butterflies and hummingbirds

Deadhead spent flowers to encourage continuous blooming; maintain consistent watering; continue light fertilizing; protect from strong winds that may damage delicate flowers

5

Post-bloom/Dormancy

2-4 months depending on climate

Flowering decreases in cooler months; growth slows; plant may drop some leaves if stressed

Reduce watering and fertilizing; bring container plants indoors in cold climates; prune back by 1/3 to encourage next season's growth; maintain warmth above 50°F
