Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with 2-4 true leaves; very delicate and prone to damping off

Maintain consistent moisture without waterlogging. Provide bright light. Ensure excellent drainage. Handle gently.

2

Vegetative Growth

4-8 weeks

Development of bushy foliage with distinctive aromatic leaves; multiple stems forming

Pinch back growing tips to encourage bushiness. Allow soil to dry slightly between waterings. Provide full sun exposure.

3

Budding

2-3 weeks

Flower buds form along stem tips; plant reaches near-mature height

Continue regular watering but allow surface to dry. Reduce nitrogen fertilizer to promote flowering. Remove competing growth.

4

Flowering

8-16 weeks (spring to frost for annuals; longer for perennials)

Tubular flowers in reds, purples, blues, pinks, or whites arranged in spikes; highly attractive to hummingbirds

Deadhead spent flowers to extend bloom season. Water during dry spells. Avoid overfeeding with nitrogen. Monitor for pests.

5

Dormancy/Winter

Variable, 8-16 weeks depending on zone

Foliage dies back or becomes dormant; minimal growth; perennials rest before spring regrowth

Reduce or stop watering in winter for tender species. Cut back dead growth in spring. Provide winter mulch in cold zones for marginal varieties.
