Growth Stages

1

Seedling

10-14 days

Tiny seedlings emerge with cotyledons and first true leaves. Plants are delicate and require high humidity and consistent moisture.

Maintain 70-75°F soil temperature. Provide bright, indirect light. Avoid damping-off by ensuring good air circulation and not overwatering.

2

Vegetative Growth

2-3 weeks

Young plants develop bushy foliage with multiple stems and leaves. No flowers present yet; plant focus is on establishing a strong root system and leaf canopy.

Pinch back growing tips when 4-6 inches tall to encourage bushier branching. Maintain consistent moisture and provide filtered or dappled light. Begin light feeding with balanced fertilizer.

3

Bud Formation & Flowering

3-4 weeks

Small flower buds appear in leaf axils along stems. Flowers begin opening in succession, displaying vibrant colors. Plant continues to grow and develop new buds continuously.

Increase light exposure gradually to full sun (if desired). Switch to a flowering fertilizer (higher phosphorus) or continue balanced feeding every 2 weeks. Deadheading is optional but can encourage more blooms.

4

Peak Bloom & Maintenance

6-12 weeks or until frost

Plant produces masses of flowers continuously throughout warm season. Growth may slow as plant matures but flowering remains prolific. Plant appears full and dense.

Maintain consistent watering during hot spells. Fertilize every 2-3 weeks. Monitor for pests and diseases. Light pruning can rejuvenate leggy plants mid-season.

5

Late Season & Decline

4+ weeks until frost

As temperatures cool in fall or if plant experiences stress, flowering may slow. Foliage may appear less vibrant. Plant is frost-tender and will die at first hard freeze.

Plants can be cut back and brought indoors before frost to extend season. Reduce fertilizing. Increase air circulation if indoors. Consider replacing with fresh plants next season.
