The Q&A Archives: Additional Care for Lemon Zest Petunias

Question: Newly purchased Petunias aren't producing new blooms or leaves. Inside leaves all brown, and plants appear to be dying or going dormant???. In good soil, full sun, no bugs? Help. Also, how to deadhead & promote new growth? I thought after blooming, the plant would continue on, or does it die out? Finally, will it come back next year?

Answer: Petunias are annual plants but in your region they will continue to grow and bloom until the weather gets cold. This can be as early as October or as late as December. Pinching out the spent flowers along with some of the stem will encourage a bushy plant with lots of new stems and lots of flowers. Wherever you pinch it back, two new flowering stems will develop. If the inside leaves are turning brown, pull them off the plant. This should promote the development of healthy new leaves. Since your petunias are annuals they will die at the end of the growing season. You can allow a few of the last flowers of the season remain on the plant and develop seeds. You can collect the seeds to replant next spring or just allow them to spill on the ground and you should be rewarded with brand new plants next spring. Good luck with your petunias!
