My white petunias have been beautiful. However, recently I have noticed that where a flower bloom should be, there is a dead little bud instead. They get full morning sun, but shade in the afternoon. It is in the 90's here in Memphis. I water frequently. Can you help?
It could be an issue with pollination. When the temps get too high, it will interfere with the normal pollination process. Another possibility is water. Even though you regularly water them, in such high temperatures, plants usually require more. Just the soil around them to make sure they are moist but not soggy. Too much water can be just as bad. They might also perk up some with the addition of bone meal too.
My petunias are getting thin and small. What do I do?
Many annuals begin to get a little leggy this time of year. Try cutting about a third of the legs back by half. When new growth begins, cut another third and so on. This should rejuvenate the looks of your petunias.
Every year I plant flowers in my window boxes, follow all the rules and put crush stone holes in the plastic containers. This year my flower's roots are being eaten and the petunias are not flourishing, others dying. What is happening?
If the roots are being eaten, it sounds like you have a small rodent like a mouse or a vole getting into your containers.

I remove spent flowers each day. But now I have many stems where blooms used to be and they are turning brown. Am I not deadheading properly?
Are you giving enough water? Bedding plants need a lot of water and the high wind we have had is very drying to plants.
I was wondering if there is a recipe for plant food for potted petunias, impatiens or fuchsia.
You might take a look at compost or manure tea. It is a good solution to fertilizing potted plants. Here is more information on it:
I recently planted some assorted flowers outside - petunias, verbena etc. and I have noticed that something is eating them and leaving little holes in all the leaves. I read about Diatomaceous Earth and thought it would be a good idea to dust the plants with this before whatever bug this is takes over and kills them entirely. I was wondering though, after the initial application what happens when it gets wet? Do I have to re-apply this stuff every time I water the plants?
Thanks! I'm gonna order some right now. I put a lot of work into creating this little garden and I cringe every time I see these little holes. I'd hate to see everything die. I want these little pests gone!
D.E. does reconstitute after it gets wet. Therefore, it will dry up and be good again. But if you're putting on plants try diluting a bit in some water and see if your sprayer can push it. Then when you spray your plants it will leave behind a coating of D.E. Apply liberally. My garden has 1/2 inch of the stuff and it works great!
Do they need more sun or shade?
sun. Maybe this article can help answer other questions you have about petunias: https://www.gardeningknowhow.com/ornamental/flowers/petunia/petunia-care.htm
