Growth Stages

1

Seedling

7-14 days

Tiny green seedlings with cotyledons and first true leaves appearing. Seedlings are delicate with minimal foliage.

Keep soil consistently moist but not waterlogged. Provide bright light (12-14 hours daily under grow lights). Maintain 65-75°F. Thin crowded seedlings to prevent damping off.

2

Vegetative

3-4 weeks

Plant develops multiple stems and dense mounding habit. Fine, linear foliage becomes prominent. No buds yet, rapid leaf development.

Pinch back growing tips once or twice to encourage bushiness. Maintain consistent watering and full sun exposure. Begin fertilizing weekly with balanced fertilizer once true leaves appear.

3

Budding

2-3 weeks

Flower buds begin forming at stem tips. Buds appear tightly clustered and pinkish in color, gradually enlarging.

Maintain consistent moisture and full sun for best bud development. Continue weekly balanced fertilization. Ensure good air circulation to prevent fungal issues.

4

Flowering

4-8 weeks or until frost

Fully double pink ruffled flowers open in profusion. Blooms are 0.5-0.75 inches diameter with fragrance. Multiple floral displays across the plant.

Deadhead spent flowers regularly to encourage continuous blooming. Water at soil level; avoid wetting foliage. Switch to higher-phosphorus fertilizer if blooming slows. Pinch off any leggy growth.

5

Decline/Frost

Until first frost

As temperatures cool in fall or first frost approaches, flowering slows and plants begin to deteriorate. Foliage may yellow.

Continue deadheading until frost to extend blooming. Reduce watering slightly. Plants are annuals and will not survive hard freezes in most zones. Some mild-zone gardeners can extend season with light frost protection.
