However, there's a trick to deadheading petunias. You cannot simply remove the petals and call it a day. Be sure to pinch the stem below the sepals to pull off the green seedpod as well. Are you trying to make a grandiflora petunia act like a milliflora petunia? If so, you may need to reevaluate your expectations or swap out your petunias for a different type. According to Iowa State University , grandiflora petunias have blooms as large as 5 inches in diameter.
These large blooms become very heavy in the rain and can cause the whole plant to look unattractive after a shower. They also don't hold up well in windy conditions. By mid-season, beaten and battered grandiflora petunias may need an intervention, such as staking or heavy pruning. Three other types of petunias exist, all with smaller but more numerous blooms. To fix a severely leggy petunia, you might have to cut the whole plant back to around one-half its present size—the pruned plant recompenses by blooming bushier, beautiful, rich blossoms than previous ones.
Pruning further helps the stems to develop fully. Deadheading is one more essential remedy to save leggy petunias. Remove faded and spent blooms so the plant can put energy into producing more flowers and not seeds.
If you notice excessive growth of leaves but fewer or no flowers, then it is the result of high-nitrogen fertilizer. Also, check yellow or falling leaves as it indicates over-fertilization.

In a range of bright colors and both single and double forms, petunias are easy to grow, grow quickly, and have a long blooming season. Petunias can be planted in borders, mass plantings, or in containers or hanging baskets. However, petunias can often become long and leggy, and at that point, blooming will slow down. With proper care, petunias will continue blooming all summer and well into the autumn months.
Pinch the tips of young petunias when the plants reach about 6 inches in height. Pinching will force the petunia plants to grow outward in a bushy, full shape rather than growing tall and spindly.
As awful as they were looking it could only go up from here. I hung them back up and kept up with watering and feeding. My roses climbing the porch posts were in full bloom and stealing the show anyway so the petunia baskets just showing a bit of green was not a huge loss for the time being.
This transformation from pathetic stubby stems to gorgeous blooms took about 3 weeks and they continued to grow and bloom the rest of the summer.
So the moral of the story…. No need to do such a drastic complete prune back if you keep up with it from day one. Deadhead regularly and cut back at least a third of the stems every other week, even if they have buds on them.
This will keep the petunias from only blooming at the ends and you keep it lush and full of blooms from the top. This is wonderful to know. We have been throwing ours away and buying new ones. Pam Panozzo. It was so hard to cut the flowers off BUT I did brave it. The funny thing is they came back all one color whereas before they were multi colored.
I cut back my petunias too. They say not to cut back after the end of July. They always come back beautifully! I supposed they say not after July as many don't have enough of a season for them to begin again, but I rarely follow rules.
So many other things are blooming around my garden we won't really miss the hanging pots for now and when everything is looking rather sad in the garden the pots will be filled out. Today's post came as the most opportune time!
Yesterday I spend some time cleaning-up my potted petunias. They were looking pathetic despite all the love I have given them! There were browned seed pods on many of the stems. I was considering trying to separate the plants, but was afraid to traumatized them too much, even though they are surely headed for the compost pile if they don't soon perk up! I will certainly give your techniques a try!
