Seedling
2-3 weeksTiny rosette of small oval leaves with visible cotyledons. Plant appears delicate but establishes quickly.
Keep soil moist but not soggy. Provide bright, indirect light. Maintain 70-75°F. Begin fertilizing at half strength once true leaves appear.
Vegetative Growth
3-4 weeksPlant develops trailing stems and multiple leaf nodes. Stems begin to cascade, but no flowers yet.
Pinch growing tips early (when 4-6 inches tall) to encourage branching and fuller cascades. Ensure full sun exposure and maintain consistent moisture. Fertilize weekly with balanced formula.
Flowering Initiation
1-2 weeksFlower buds form at branch tips and leaf axils. Small white buds become visible throughout the plant canopy.
Begin weekly fertilizing with higher phosphorus formula to promote blooming. Maintain full sun and consistent watering. Remove any damaged leaves.
Peak Blooming
8-12 weeks or until frostAbundant small white flowers cover the trailing stems, creating a cascading floral display. Flowers appear continuously.
Deadhead spent flowers (optional, as Multiflora types are self-cleaning). Water consistently; container plants may need daily watering. Fertilize every 7-10 days with bloom-promoting formula. Watch for pest infestations.
Decline/End of Season
Variable; ends with first frostAs temperatures cool (below 50°F) or day length decreases, flowering slows. Plant becomes leggy if not maintained.
Plant is frost-tender and dies at first hard frost. In mild climates (9b+), may persist into fall with reduced vigor. Remove and compost at season end.

Harvest Tips
Petunias are ornamental flowers for cutting and display. Deadhead spent blooms regularly (though Multiflora types are largely self-cleaning) to maintain appearance and encourage continued flowering. Cut stems with 3-4 leaf nodes in early morning for fresh arrangements; stems typically last 5-7 days in water. Can be harvested continuously from peak bloom through fall.
Fun Facts

- 🌱 The name 'Surfinia' reportedly evokes the image of waves, reflecting the cascading, wave-like appearance of the trailing stems laden with flowers.
