Donna, there are some hybrid petunias that actually carry a gene that causes them to fade. There probably isn't much that you can do other than replace your petunias. You might consider contacting your county extension agent or a local nursery for suggestions.

Pam, the rain may or may not be a factor. It is possible that this is a fungus called Cerospora Petuniae. Characteristics of this fungus are oval-shaped brown spots that have a grayish-white center with a darker brown border. If this is your case you may be able to control it with a fungicide labeled effective for Botrytis.

You might consider visiting your extension office as well. If you bring them a sample they may be able to give you a more definite answer.

Thank you both for your questions.

My petunias are fading - the flowers were a brigh purple but not the purple seems to be fading. I water them regularly - they get the afternoon sun. I did purchased a fertilizer called "color burst" and sprayed it on the flowers. I regularly pick off the dead flowers to encourage new flower growth.

The leaves of most of my Petunis plants have brown, rusty marks on the back of the leaves, what has caused this. Each basket was planted with new compostand I have dead headed them regularly. We have had far more rain than uSaul, do you think this is a contributary factor/

Is it normal for many of the leaves on petunias to fall off immediately following planting? They get a lot of sun and I have been watering them, but many of the flower petals have fallen off.
