Growth Stages

1

Seed germination

1-2 weeks

Tiny seedlings emerge with two oval cotyledons; seeds germinate in 7-14 days at 70-75°F

Keep soil consistently moist but not waterlogged; provide bright light immediately after sprouting; avoid overheating seedling trays

2

Seedling & early vegetative

3-4 weeks

True leaves develop; plants form a compact base with 4-6 leaves; height 2-3 inches

Thin seedlings to 12-inch spacing if direct sowing; provide good air circulation; begin hardening off transplants one week before planting

3

Vegetative growth

3-4 weeks

Rapid stem and leaf development; plants reach 12-18 inches tall; bushy, branching habit forms

Pinch back tops at 6 inches to encourage branching and bushier plant form; consistent watering aids growth; deadhead spent flowers to promote more branching

4

Flowering & blooming

6-10 weeks or until frost

Abundant daisy-like flowers with ruby-red petals edged in bright yellow; flowers 1-1.5 inches across; continuous blooms

Deadhead spent flowers regularly to extend bloom time; provide consistent moisture during peak heat; stake tall varieties if needed; fertilize lightly every 3-4 weeks with balanced fertilizer

5

Seed production & decline

Until first frost or plant decline

Flowers transition to seed heads; plant may slow blooming in fall as temperatures drop; foliage may yellow

Allow some flowers to remain for self-seeding next year; or deadhead to keep plants blooming longer; reduce watering as growth slows; annual types will die at frost; perennials may regrow from roots

Harvest Tips

For cut flowers: harvest in early morning when flowers are just fully open; use sharp shears and place immediately in water; flowers last 5-7 days in a vase. For seed saving: allow flowers to fade naturally on the plant; collect dry seed heads before they shatter; store seeds in cool, dry place. Deadhead regularly throughout the season to encourage continuous blooming.
