If you want to fill a flower bed or large planter with an eye-catching pop of color, Wave petunias are the plant to get. This relatively new petunia variety has taken the gardening world by storm, and rightly so. Growing Wave petunias is even simpler than caring for their earlier petunia cousins, which makes them ideal for busy gardeners and novice growers alike. Learn how to care for Wave petunias and you may discover a new favorite flower.

Growing Wave Petunias

Wave petunia plants have a spreading growth habit, with the ability to fill flower beds with their blooms that sprout all along their stems, which can reach up to 4 feet. Wave petunia plants are so versatile they can accent almost any part of your landscaping design.

Create a dense hedge covered in blooms by planting a row of these plants along the base of a 3-foot fence for support.

Decorate a porch roof with giant globes of color by planting bright Wave petunias around the base of a coir basket.

Add them to large planters near your front door and allow them to cascade to the ground.

Plant a double row of them from the street to your porch to create a lined floral path.

How to Care for Wave Petunias

Caring for Wave petunias is a simple task and won’t take much time at all. These plants want to grow and thrive, and seem to increase on a daily basis.

Plant them in full sun in moist, well-drained soil. Keep the soil moist, but never soggy.

Feed them with an all-purpose fertilizer when you first plant them, and every two weeks after that until the middle of summer.

Do you have to deadhead Wave petunias? This is the sheer genius of these plants, and what makes them so popular for use all over the garden. Unlike other petunia plants that need clipping and deadheading constantly throughout the growing season, Waves never need deadheading. They will continue to grow and bloom without your having to snip one bloom.
