How to preserve petunias: 5 important tips from experts
Petunias are perfect as front door plants to brighten your entryway. They are known as fly repellent plants that make the yard a more pleasant place to spend time. They will add a rainbow of color as yard plants, so you will want them to keep them in bloom for as long as possible. These are the techniques gardeners use to keep them blooming.
1. Keeping up with a dead end
Learn how to kill petunias and you can keep them blooming. “Although we grow most plants for their decorative flowers, they actually flower to produce seeds,” explains horticulturist Steve Bradley.
“Once the flower is pollinated and the seed embryo is fertilized, the plant feels it has done its job and gradually stops producing flowers. Then all the plant’s energy goes to the developing seeds.
“With petunias, deadheading can be carried out as soon as the tubular flowers begin to collapse, but it is best to wait until the flowers begin to wilt and die. At this point, the entire flower has separated from the plant, rather than being torn off, and the easiest way to remove it is to uproot it with a Finger and thumb.

2. Consider pruning
In addition to deadheading, pruning may be necessary to prolong the flowering period. “Most petunias, especially petunias, produce most of their leaves and flowers at the tips of the shoots, which means the bases of the stems can become bare and woody,” says Steve Bradley.
“Cutting back old stems by at least a third can encourage new buds to form near the base of the plant.”
3. Put them in the sun
Petunias bloom best in direct sun. Petunias need at least five or six hours of good sunlight; “They will do best when they are in full sun all day,” say experts at the University of Minnesota.
Well, this tip won’t help you now if you’ve already planted your petunias in a shaded bed or border (although it will be useful for the future). But if you place these colorful flowers in the shade when they are in containers or hanging baskets, you can move them to enhance flower production.
4. Water according to where it is grown
For lush petunias and a gorgeous flower display, keep watering. If they are in a bed or border, a thorough watering once a week should be sufficient. Soak the soil to a good depth (we’re talking about 6 inches); This helps them produce deep, healthy roots.
Keep in mind that petunias in containers need to be watered frequently and that adequate watering of hanging baskets is equally important—even as much as they may require daily care because they dry out more quickly. Water the pot until you see water flowing from the base.
5. Feed petunias
Petunias need fertilizer to make their best flower display. “Petunias are hungry plants and need regular feeding with a high potash feed as soon as the first flowers open to help increase and prolong flowering,” advises Steve Bradley. “Regular liquid feeds tend to have a more immediate effect on the performance of flowering plants.”
What happens if you don’t cut your petunias?
If you do not plant dead-headed petunias, you will not encourage your plants to produce new flowers. a result? Your wonderful flower display will likely end soon. But there are exceptions. Supertonia and spreading corrugated petunias do not require deadheading and continue to bloom vigorously. As for the spent flowers, they fall so as not to hinder the new flowers.
