Seedling
10-14 daysTiny seedlings with first true leaves appearing; very delicate and slow-growing initially
Keep soil consistently moist under grow lights or bright windowsill. Maintain 70-75°F. Provide excellent air circulation to prevent damping off. Do not cover seeds; they need light.
Vegetative Growth
14-21 daysPlant develops multiple sets of true leaves and bushy branching structure; no flowers yet
Pinch tips when 3-4 inches tall to encourage bushiness. Maintain consistent moisture and feed weekly with diluted balanced fertilizer. Harden off before transplanting outdoors.
Pre-flowering
7-10 daysPlant reaches full compact form (6-12 inches tall/wide) and bud formation begins at branch tips
Increase light exposure and reduce nitrogen fertilizer. Begin transitioning to outdoor conditions if starting indoors. Space plants adequately for air circulation.
Flowering & Blooming
60-120 days (spring to frost)Hundreds of small (0.75-1 inch) flowers in jewel tones cover plant; continuous bloom throughout season
Deadhead spent flowers to encourage continuous blooming, though millifloras are self-cleaning. Water regularly, especially during heat. Feed every 2 weeks with low-nitrogen, phosphorus-rich fertilizer.
Decline & End of Season
As weather dictatesFlowering slows as temperatures drop or frost approaches; plant stops producing new blooms
Remove plants before first hard frost in most zones. In zones 9-11, can cut back severely for rejuvenation or allow light frost exposure.

Fun Facts
- 🌱 Petunias are native to South America and were first brought to Europe in the 1800s, becoming one of the most popular ornamental flowers worldwide.
- 🌱 The Mirage series was specifically bred to be self-cleaning, meaning flowers naturally drop as they fade without requiring deadheading, making maintenance minimal.
- 🌱 Milliflora petunias produce 50-100+ times more flowers per plant than standard varieties, earning them the name 'million flowers' from their profuse blooming habit.
