Also know, what causes petunias to stop blooming?

Reasons for Petunia Not Blooming The plant may bloom when it is lightly shaded for part of the day, but as a rule, a petunia not blooming can be because it does not get at least six hours of direct sun per day. Move container planted petunias plants with no flowers into a sunny location.

Additionally, how long do petunias last? How long do the plants themselves actually live for, or perhaps you want to know how long the flowers last once your petunias bloom? To tackle the first part of the question, petunias can live for 2 or 3 years but generally behave as annuals because they can't survive the freezing temperatures of the winter.

Consequently, should you cut back petunias when they get leggy?

Trim back petunias in midsummer if they become leggy, overgrown and begin flowering poorly. Remove half of the plant stem's length by cutting the petunias down with garden shears. Shearing back forces the petunias to send out new compact stems.

How do you keep petunias blooming all summer?

To encourage additional blooms from petunias, old blooms should be removed through deadheading to encourage new blossoms instead of seed production.

  1. Look for signs that petunia blooms are beginning to fade and die.
  2. Remove, or deadhead, the petunia plant by hand.
