Petunia Care Tips

Petunias are no doubt one of the most popular annual flowers and best to grow in containers. However, in warmer areas (considerably USDA Zones 9-11), they are tender perennials. Growing Petunias in Containers have some requirements, and you can do it easily by following these Petunia Care Tips!

Petunia Care Tips

1. Soak in the Sun

To bloom abundantly, petunias require a good soak in the sun for at least 5-6 hours. They love warmth and sunlight. Keep your potted plants in a spot that receives full sun.

Tip: Those living in USDA Zones 9-11 and other warmer regions can provide shade in the afternoon.

2. Watering is Essential

Petunias may recover from the underwatering shock, but overwatering is the main reason why container-grown petunias die. This attractive flowering plant requires moderate watering and slightly moist soil during the day. Water regularly but let the soil dry out between the watering spells to avoid root rot.

3. Provide the Right Soil

For growing the best petunias in pots, your growing medium must drain freely. A soil-less mix is right for this purpose. Either buy it or make your own. We have a great article on making potting mix here

4. Fertilize for Prolific Blooms

Petunias are greedy and needy plants when it comes to fertilizer. Either apply slow-release fertilizer at the time of planting or feed them every other week using the diluted liquid fertilizer like 10-10-10.

Additionally, the application of compost on top of the surface can be made too. If your container-grown petunias have lush foliage and less or no flowers, you may need to apply a fertilizer that is low in nitrogen.

5. Pinching Them!

If you’ve bought petunia plants from a nursery or growing them from transplants, pinch off the top one inch from each stem and remove all flowers.

If grown from seeds, baby petunias (multifloras and grandifloras), when they’re 5-6 inches tall, pinch them back a little to promote more vigorous side shoots. Milifloras (spreading petunias) don’t require this.

6. Deadheading is Must

This is one of the essential petunia care tips you need to follow. Remove faded flowers so that the plant can concentrate its energy on producing more blooms. It’s also important to remove the seed developing portion below each flower.

7. Look at Pests

Common garden pests, especially aphids, affect this beautiful flowering plant the most. So keep an eye on them and look on and under the leaves to identify the infestation.

  1. Love the information. Have loved petunias since I was very young,my mamaw grew loads of them in east Texas, you could smell the scent of the dark purple ones as soon as you were near her house. I’m in hot dry S.Tx.now and have had very little luck growing petunias here, will try your tips, wish me luck 🐝

  2. Petunias love heat? Then mine must be freaks. I live in N. California about 1/4 mile from the ocean and lots of wind. My plants in containers are blooming their heads off.

  3. Millifloras : Milliflora petunias are much smaller than any other petunias on the market. The flowers are only 1 to 1? inches wide, but they are prolific and last all season!
