Because of the globe-shaped habit, this plant has a perfect presentation as a petunia in for containers and hanging baskets for containers and is a star in landscapes where it won’t sprawl too wide to cover pathways as a trailing petunia plant or take over neighboring plants.

Supertunia® petunia plants are easy to grow and will flower non-stop from planting to hard frost if simple maintenance tasks are performed. Growing Supertunias in full sun to part sun is important for their strong growth and bloom performance. They do not require deadheading, meaning the removal of spent flowers, to stay in bloom all season.

Petunias thrive with consistent moisture. Do not let them wilt severely before watering again.

Supertunia petunias perform best when fed regularly with Proven Winners plant foods. At planting time, in containers and landscapes, mix Proven Winners Premium Continuous Release Plant Food into the soil, following the rates specified on the packaging. Reapply halfway through the growing season.

Additionally, Supertunias should be fed regularly with Proven Winners Premium Water Soluble Plant Food according to the rates specified on the packaging. For Supertunias growing in containers, feed every third time you water or at least once per week. For Supertunias growing in the ground, feed once every one to two weeks.

If you have been feeding your petunias regularly and they are getting enough sun and water but are not blooming, you may be dealing with petunia budworm. Learn more about this petunia pest.

By midsummer, it will be time to trim up your Supertunias. Trim the longest stems, bringing them in line with the others, taking care not to remove more than 20% of the plant. Trimming petunias in the landscape is not usually necessary but cutting them back by 20% can make the plants fuller. Follow up by feeding them with water soluble plant food to promote fresh new growth and blooms.
