Plant in Full Sun for Best Blooms
Petunias love the sun—no shade-loving behavior here! For a field of petunias that truly puts on a show, aim to give them at least 6 to 8 hours of direct sunlight daily. Any less, and you risk fewer blooms, leggier growth, and a sluggish overall performance.
Sunlight is what fuels their blooming engines. It helps keep the plant compact, encourages stronger branching, and keeps mildew at bay. Full sun also attracts more pollinators and keeps the soil warm, which is especially important early in the season. Petunias practically radiate happiness when they’re basking in bright light!
