In general, the only pruning a Mexican petunia requires is an annual pruning in late winter or early spring to remove damaged, weak or otherwise undesirable stems back to the base of the plant. Cutting back spent flower stalks during the blooming period helps maintain a neat appearance.
Why did my petunias suddenly stop blooming?
If your Wave petunia has stopped blooming the reason is likely due to not giving the plant the care it needs. If you are providing the plant with the water, sun, and fertilizer it needs and it still isn’t blooming, then it might be due to a disease or insect infestation.
How do you make Mexican petunias thicker?
Pull off withered blossoms with your fingers. Look for the growing point on the stem of the plant and pull off the tip of it with your fingers. This will thicken the plant by causing more flowers to bloom from the same plant. Cut off dead and dying petunia plants in your flower bed.
Do Mexican petunias multiply?
Mexican petunia usually spreads by rhizomes. You can produce new flowers by cutting the connection between the mother plant and the new shoots. After transplanting these pieces into the garden, young plants will grow quickly. The best of all is that you can expect them blooming very soon.
How do you get petunias to bloom again?
To encourage additional blooms from petunias, old blooms should be removed through deadheading to encourage new blossoms instead of seed production.
Look for signs that petunia blooms are beginning to fade and die. Remove, or deadhead, the petunia plant by hand.

Troubleshooting Petunia Wilting Problems
Like lots of plants, petunias respond to a lack of water by wilting. Don’t just water them more though! Wilting petunia flowers can also be a sign of too much water. Always check the soil around your petunias before watering–if the soil is still damp, don’t water it.
How do you care for Mexican petunias?
Mexican petunia grows and blooms best in full sun or partial shade. It will grow in shade, but doesn’t bloom as much and looks leggy and lanky. This sun-loving perennial likes rich, slightly moist soil so mulch the plants to maintain consistent soil conditions, especially during hot, dry weather.
Will petunias rebloom if cut back?
You will have a full, compact blooming petunia plant in a couple of weeks. You can also cut back (by 1/4 or 1/2) just some of the branches scattered evenly throughout the plant. Those branches will regenerate and rebloom, and then you can cut back the remaining branches two weeks later.
