Key Points
Petunias need at least six hours of full sun daily to keep blooming—too much shade will halt their flowers.
Regular deadheading and occasional pruning help petunias regrow fuller and rebloom more consistently.
Keeping soil consistently moist, especially in heat or containers, is key to preventing wilting.
Petunias are often a top choice for many gardeners since they come in a range of colors and can easily be layered with other flower types to boost outdoor appeal.
Although it’s easy to assume they only bloom once throughout the season, there are a couple of tricks you can use to actually make them rebloom so your garden stays colorful and lush throughout the summer season.
Below, we tapped pro gardeners to share their best tips for making petunias rebloom.
Meet the ExpertsPick the Right Location
The first thing you need to consider when planting petunias is the location, since they need full sun and at least six hours of direct sunlight, Laura Janney, the CEO of The Inspired Garden Masterclass, says.
“I’ve seen cases where Petunias bloom beautifully in early spring when sunlight filters through bare trees, but then stop blooming once the trees leaf out and there’s too much shade,” Janney explains.
If you notice your petunias are not getting enough sun, it’s recommended to move them to a sunnier location.
Pinch Off Faded Flowers or Cut Back
To ensure continuous production, Anna Ohler, the owner of Bright Lane Gardens, suggests pinching off any faded flowers, including the seed pod. If you also notice your petunias becoming leggy or overgrown, cut them back by half.
“They will rebound thicker and will continue to produce after being pruned,” Ohler says,
Janney agrees and recommends giving a light trim every now and then.
“Using a pair of pruning shears to cut them back will encourage new growth,” Janney says. “Within about a week, you’ll see your petunias bounce back even better than before.”
Keep an Eye on Watering
Since petunias like moist (but not soggy) soil, they may often need daily watering or multiple waterings throughout the day if there’s extreme heat, if they’re in hanging baskets or containers, Janney explains.
If you notice your petunias wilting on a hot afternoon, that’s a big indicator that they need a good watering. In-ground Petunias can usually go a bit longer between waterings, Janney says.
