This summer all my petunias got white and green bugs on them. I bought a commercial spray to get rid of the bugs and it took the color out/off the petunias. What can I do, as I love petunias in the summer?
We recommend neem oil. We like it as a pesticide because it is safe for humans and pets and is very effective against damaging bugs, but does not hurt helpful bugs like bees and butterflies.

I enjoy growing petunias from seed but had found it difficult to handle the tiny seeds and waiting for them to germinate. I have heard that there are sources which provide germinated plants to commercial growers. Could you please provide a source for such plants?
We cannot recommend places to purchase, however, we can offer information on their care:

I have a potted petunia plant that was doing well and blooming continuously. It gets plenty of sunlight, watered regularly, and I am careful to pick off the dead blooms with their seeds.

I live in Phoenix, Arizona. It is June and my petunias were blooming and cascading out of their pots on my porch, then the flowers were eaten and I found green caterpillars. Is there a home pest solution I can make and use, or is it better to just by a pesticide for these PESTS?

I love petunias and super bells. I know they are full sun, but can they still do well if the container they are in is in a shaded area?
They may grow, but they will not bloom well in the shade. You might like wishbone flowers as a replacement.
