    Pinch the ends of the plant off by 1/3 and the plant should bounce back and bloom nicely!

    Cut the petunias back. They will grow in a lot fuller and produce more flowers.

    I just deadhead mine like a lot of other flowers. Just pinch off the dead flowers every day or as often as you can. I have 1/2 dozen hanging baskets of petunias and they stay loaded with flowers for the past couple of months. It's super hot down here along Gulf coast and they dry out almost every day now when it doesn't rain. So I've had to water virtually every day. But they seem to need to dry somewhat between watering. At first I had them in full sun, but now they seem to d better in partial shade.

    yes, pinch off the spent flowers. This is called deadheading and helps the plant produce more.

    Larger Petunias have to be dead headed. If you take one plant and remove the first couple rounds of blooms your plants will grow much bigger and you will need to purchase 1 plant instead of 4-5. The smaller versions of petunias will deadhead themselves.

    It's true they need to be deadheaded, but if the buds died before blooming, then it may be they got too wet and rotted., or too dry and shriveled and dried up. The answer is in your recent weather and your watering pattern. Be careful to water the roots not the foliage or flowers.

    You can get fertilizer that is for making more blooms on any plants that bloom. I have never had petunias die from too much water or rain. I do put them in a container that has a drain hole or two. I even bought some of the small petunias that deadhead themselves and when fall came I thought I would just wait until spring to take them up and get rid of them. To my surprise they has some green all winter and grew and rebloomed this spring. It got pretty cold during the winter also.

    Hi there, Petunias need lots of full sun to really do well and not to much water. They're extremely water wise too. You can read more about caring and growing them here -
