Growth Stages

1

Seed Germination

2-3 weeks

Seeds germinate in 7-14 days at 65-70°F. Seedlings develop their first true leaves.

Keep soil moist but not soggy. Provide bright, indirect light. Do not cover seeds.

2

Seedling & Vegetative Growth

4-6 weeks

Plants develop multiple leaves and establish root systems. Stems become sturdy and upright.

Thin seedlings to proper spacing. Water regularly. Fertilize with balanced fertilizer every 3-4 weeks. Protect from excessive wind.

3

Bud Formation

3-4 weeks

Dense clusters of flower buds form at the top of stems. Stems continue to elongate and strengthen.

Increase watering during dry spells. Apply balanced or phosphorus-rich fertilizer. Stake tall varieties if needed.

4

Flowering

4-8 weeks

Brilliant scarlet-red, cross-shaped flowers open in dense terminal clusters. Flowers are long-lasting and attract pollinators.

Deadhead spent flowers to encourage continued blooming. Water during dry periods. Provide support with stakes if needed.

5

Seed Development & Dormancy

4-6 weeks

If flowers are not deadheaded, seed pods develop and dry on the plant. Plants begin to decline after flowering.

Leave some flowers for self-seeding if desired. Cut back stems after frost or allow to dry for ornamental effect. Mulch for winter protection in colder zones.
