Growth Stages

1

Seedling

2-3 weeks

Small plants with 2-4 true leaves, delicate and tender

Keep soil consistently moist but not waterlogged. Provide bright light to prevent legginess. Thin seedlings to proper spacing once true leaves appear

2

Vegetative

3-4 weeks

Bushy growth with increasing leaf development, no flowers yet

Ensure full sun exposure. Pinch growing tips when 4-6 inches tall to encourage branching and bushier form. Water regularly and provide balanced fertilizer

3

Budding

1-2 weeks

Visible flower buds forming at branch tips, plant becoming fuller

Continue regular watering and fertilizing with balanced or flowering-focused fertilizer. Avoid excessive nitrogen which delays blooming

4

Flowering

8-12 weeks or until frost

Semi-double orange blooms opening continuously; plant covered in flowers

Deadheading is minimal but optional for extended bloom. Water consistently at soil level. Continue fertilizing every 2-3 weeks. Enjoy continuous color all season

5

Decline

2-4 weeks until first freeze

Flowering slows with cooler fall temperatures and approaching frost

Plants will decline once temperatures drop below 50°F. Harvest seeds before first frost if desired for next year. Remove and compost spent plants
