The trailing varieties, such as surfinias, are perennial and grow in the spring and summer.

Can petunias come back every year?

Petunias are perennials, however, they are typically treated as annuals. They will bloom over the winter months in warm climates. If you want your petunias to grow back in the spring, then you need to store them for at least a few months before planting them.

Are petunias an annual or a perennial?

Petunias are bright and lively, bloom from spring until frost, and scent the air with a lovely fragrance. Petunias are easy to grow in the garden and in your home. The easiest way to get started with growing a petunia is to plant it in a pot.

You’ll want to add a few inches of water to the bottom of the pot to keep the soil moist, but you don’t need to water it as much as you would if you were growing an annual. Once your plant is established, it will take about a month or two for the roots to reach the surface.

This is a good time to prune the plant to make room for new growth. After the root ball has grown to about 1/2-inch in diameter, cut it back to its original size and transplant it into a larger pot or container.

Can I save my petunias for next year?

The petunia can be kept alive in a greenhouse by being treated as a houseplant. Dormancy is the process of keeping a plant dormant for a period of time. It’s a good idea to keep your petunias in the same room as your other plants. This way, if one of your plants dies, the other will be able to take its place.

If you want to make sure your plant doesn’t get too cold, place it in an air-conditioned room with a fan blowing on it. You can also use a heating pad to help keep the temperature of the room at a comfortable level.

How do you keep petunias over the winter?

Place the plants in a location that is above freezing. They’ll be out of the way if you put them in your garage or basement. The petunias need to be checked every three to four weeks. If the soil has dried out, give the roots some water.

If the plant is not overwintered, it will need to be watered every two to three weeks to keep it from drying out. You can also add a few drops of liquid dishwashing detergent to the potting soil to help it stay moist.

Will petunias regrow if you cut them back?

Petunias look leggy or have sparse stems. New flowers emerge at the ends of stems, so as old blooms die back, the stems will look bare. Cutting a Petunia back in the middle of the season will allow the plant to push out new growth and appear more full. At any time, dead or damaged growth can be removed. Plant in well-drained soil and keep the soil moist, but not soggy.

Do not overwater, as this can cause root rot. Keep the potting mix moist but do not allow it to dry out. The soil should not be too wet or too dry, and the plants should never be allowed to sit in water for more than a day or two at a time, or the roots will rot and die.

Are petunias permanent?

Petunias are treated as annuals in most areas, but can be grown as tender perennials in Zones 9 to 11. The flowers come in many colors and patterns, and bloom from spring to early summer. Prunus serrulata is an evergreen shrub or small tree that grows to a height of 10 to 15 feet.

It is hardy to Zone 9 through Zone 11, although it may be difficult to find in some areas. Zone 10, it is a deciduous tree, which means that it dies back in the spring and is replaced by a new growth.
