Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds sprout in 7-14 days. Seedlings develop true leaves and become bushy.

Keep soil moist but not soggy. Provide bright light (60-70°F optimal). Avoid damping off with good air circulation.

2

Vegetative Growth

3-4 weeks

Plant develops dense foliage and branching structure. Leaves are small, finely textured.

Pinch growing tips when 2-3 inches tall to encourage bushiness. Begin fertilizing with balanced fertilizer every 2 weeks.

3

Budding & Early Flowering

1-2 weeks

First flower buds appear on branch tips. Plant becomes compact and full.

Continue pinching for fuller form if desired. Water consistently. Switch to bloom-promoting fertilizer (higher phosphorus).

4

Peak Flowering

6-12 weeks

Abundant bi-colored flowers cover the plant. Flowers continuously if deadheaded.

Deadhead spent blooms regularly to encourage continuous flowering. Water deeply but allow soil to dry slightly between waterings. Feed every 2 weeks.

5

Late Season/Decline

Variable; until first frost

Flowering may slow in extreme heat or with frost. Plant may become leggy.

Cut back by one-third if plant becomes overgrown. In fall, may rebound with cooler temperatures. Remove if frost threatens.
