Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds sprout within 5-10 days at 65-70°F. Seedlings develop thin stems with narrow opposite leaves.

Keep soil moist but not soggy. Provide bright light and good air circulation. Thin seedlings to proper spacing. No fertilizer needed at this stage.

2

Vegetative Growth

3-4 weeks

Plant develops a bushy, compact mound of narrow, blue-green foliage. Stems become sturdy and branched.

Pinch back growing tips once or twice to encourage bushier growth. Water moderately. Apply balanced fertilizer every 2-3 weeks. Ensure good drainage.

3

Budding

2-3 weeks

Tight flower buds appear at branch tips, initially appearing as small green knobs that swell and develop sepals.

Maintain consistent moisture without overwatering. Continue light feeding with phosphorus-rich fertilizer to support bud development. Mulch lightly.

4

Flowering

8-12 weeks (extends with deadheading)

Abundant small, ruffled flowers with fringed petals open in clusters. Flowers display sweet fragrance and vibrant colors. Blooms continuously with deadheading.

Deadhead spent flowers regularly to promote continuous blooming. Water during dry periods. Reduce nitrogen to prevent excessive leaf growth at flowering expense. Enjoy cut flowers.

5

Decline/End of Season

Variable

Flowering slows as temperatures rise (heat stress) or as season progresses into fall/winter. Plants may decline in appearance.

In hot climates, provide afternoon shade or allow plants to rest. Cut back faded plants by half to rejuvenate. In cooler zones, may persist through winter. Remove dead foliage.
