Help! I planted a row of petunias in my lawn and I heard they die after a season?

Is this true? I planted them with the thought that they will last for years, but they're annual, so I guess they die after a year and I have to buy new ones and replant them? They don't drop seeds and regerminate or what? Thanks in advance.

They are annuals, and they will die out once the cold weather hits and not come back next season. You don't say where you live, but in extremely warm winter areas(Florida, parts of southern TX and CA) they may come back, just don't count on it. Try daylilies - they are pretty flowers and continue to grow and spread from year to year.
Reply:We treat them as annuals.





They will drop seeds, but most of the time the resulting plants are not true to color or form of the desired parent plant. In fact after several seasons, if the seeds overwinter, they will revert to the more natural white and lavenders.





I have grown a petunia inside during the winter, near a sunny window.





I have seen volunteer petunias grow on landscape rock, at the edge of a building and parking lot, in the cracks of a sidewalk, etc.





Don't be afraid to replant your petunias (or other annuals) each year. They are pretty inexpensive and give you loads of color and enjoyment during the growing season. Remember to pick off the dead blooms (nip off the seed heads before they takes hold) and you will have loads of blooming petunias this summer and into the fall.
Reply:This is interesting because a funny thing happened to me this spring. Last year I had petunias in pots along the patio. The rabbits eventually ate all of them. My contribution to the animal kingdom. This spring, all along the patio, I have a mass of petunias. They are even in one of the pots that didn't have petunias last year; but not growing in the pots that did have petunias. This is interesting, because I live in Iowa and we had a few nights of well below 0 weather. So, they don't usually come back the next year, but I guess you never know.
Reply:Petunias are annuals for the most part, but sometimes they have seeds and they will germinate the following year, but certainly not the way each plant will when planted after buying them from a local nursery.
Reply:Sometimes they'll seed themselves.


Here's a tip...look up what you want to plant before you actually do.


Pansies are more likely to reseed themselves.
Reply:Petunias are an annual in most climate zones in the U.S. They are one of the more hardier annuals, meaning they can tolerate a light frost, but if the temperature gets below 29 F or so, they will die. You can start petunias from seeds, but I have never seen them reseed themselves the following spring. They are such a consistent performer and are generally take a little more neglect than most annuals. That being said, water them when the soil feels dry and fertilize them regularly to get best results.





Good luck and enjoy your flowers!
