How to Grow Climbing Petunias

Where it Grows

Climbing Petunias will perform best if they're grown in pots or containers, but they can also be grown right in your garden beds. Wherever you decide to plant them, give them an adequate support system. If they don't have a trellis or any sort of vertical support, they won't be able to grow to their full potential.

You'll be amazed by their vertical growth and abundance of blooms. Get creative with the type of support system you give it to create more garden intrigue.


This variety of Petunia can reach a height of 6 feet, once fully grown. Their climbing ability is what makes them so unique; it's unlike any other Petunia variety. Their stems are long and lax, making a strong support system necessary for their vertical success. If it's not trained to grow vertically, it will have a massive spread and work well as a ground cover plant.

Deadhead your flowers to promote future growth and for the continued health of the plant. Pinching the plant at the initiation of each growing season encourages branching and more abundant blooms in the future.

Optimal Growing Zones and Conditions

Climbing Petunias grow as tender perennials in USDA plant hardiness zones 9 through 11, and annuals in the other zones. They tend to prefer growing in warmer climates.

Ideally, its best to plant these Petunias where they'll have some protection from strong wind. Since this variety has a shallow root system, considering planting them in a region that won't receive pools of water.

Type of Soil

Rich, moist, well-draining soil is optimal for this type of Petunia's success and health. In order to reach its full potential, it will need the perfect blend of soil. If your soil is rather devoid of nutrients, consider adding in compost to help fill it with nutrients.

Light, Watering, and Fertilization Requirements

Climbing Petunias grow best in full sun, but they can also grow in partial shade. Luckily, these plants are rather weather-resistant, so they can handle a wide variety of conditions. Getting at least 6 hours of sun during their growing season will give them the healthiest, most abundant blooms.

Water this plant regularly. If planted in a container, you'll have to keep a more careful watch on making sure you give it an adequate supply of water. Though they're drought-tolerant, it's best to water them more during hot, dry spells if you can.

Fertilize your Petunias consistently to provide supplemental health support. Use a combination of liquid and slow-release fertilizer every 10 to 14 days. This will ensure the continued health of your Petunias.
