Growth Stages

1

Germination

7-10 days

Seeds sprout with cotyledons emerging from soil; two round seed leaves appear

Keep soil warm (70-75°F) and consistently moist. Thin seedlings to proper spacing once first true leaves appear.

2

Vegetative Growth

3-4 weeks

Plant develops multiple true leaves and branching lateral stems; compact bushy growth habit

Ensure full sun exposure. Water consistently. Pinch central stem when 6-8 inches tall to encourage branching and bushier habit.

3

Budding

2-3 weeks

Flower buds form at stem tips; plant reaches near full height

Maintain consistent watering and full sun. Apply balanced fertilizer weekly or use slow-release formula. Stake if grown in windy locations.

4

Flowering

4-6 weeks

Large golden-yellow flowers bloom with dark brown/black centers; flowers face the sun early in day

Continue regular watering but reduce nitrogen to avoid excessive foliage at expense of flowers. Deadhead spent blooms to encourage more flowering.

5

Seed Development

3-4 weeks

Flower petals drop; seed head enlarges and seeds mature within the disk

Reduce watering gradually. Do not deadhead if saving seeds. Allow seeds to fully dry and turn brown on the plant.
