Tall, healthy shastas but no blooms. 3 different locations in yard, leaves look great, a tight whorl on top where the flower should form of a lighter green. All the plants receive lots of sun with a little shade from other plants at different times of the day. I have added phosphate to encourage blooms to no avail.
Other than having an abundance of nitrogen in the soil, which is normally offset with phosphorus, I really don't know what else would be keeping the plants from blooming. You may need to get a soil test to see exactly what, if anything, needs to be corrected as far as nutrients go, but the addition of bone meal shouldn't hurt.
As soon as my Shasta daisies bloom, the petals open up curled; they almost look like they are wilted, but we've had a lot of rain, so I really don't think that is the problem. There are plenty of blooms and dozens that are getting ready to open, but they are all opening the same way. Any idea what the issue might be?
Thanks for the suggestion on the neem oil; I'll give it a shot. Do you recommend getting the concentrate or ready to spray? If I need to mix it, what's the best way to do that and apply it? I've read about a lot of different products and I'm pretty confused at this point! Thanks in advance :)
This is probably caused by Aphids on your plants.
You can treat the plants and flowers with Neem Oil.
Neem Oil is organic and safe for people, pets and Bees.

We have a plant that looks like it's some kind of daisy. It's growing like a weed. Last year when we had flower bed installed, the landscaper put in three plants. Now we have lots of them. The plant produces a single white flower that looks like a daisy. What plant is this and how can I control its growth?
You do most likely have Shasta Daisy growing.

Even with regular watering, my Shasta Daisy is wilted all the time. It gets both sun and shade. It is a new plant-bought 4 weeks ago. We are having lots of heat-in the 90's every day.
New plants and very high temperatures will require extra water to keep them alive.
Is the soil draining to quickly for the moisture to be held? Or is the plant receiving to much water? This could also be indicated by wilting.
Here is a great article that should help you pinpoint the issue.

My Shasta Daisies are dying. When they bloomed, something ate the petals off the flowers. I deadheaded them and then the plant started dying. I have two different clumps of daisies in different spots in my yard. The bugs I saw on the daisies resembled tiny bees. I have never had trouble growing daisies until last year and same story this year, even after buying new plants and replacing them. Hope you can help.
It's unclear what exactly is causing the issue with your Shasta Daisies, the tiny bees may just be that little sweat bees. They would be harmless to the plant.
I would treat them with Neem OIl. This acts as both a insecticide or fungicide.

I have a potted Shasta daisy. It has bloomed some this summer but now seems to not have any blooms or buds. Is this normal?
Regular watering and dead heading can help extent the flowering of your daisy plants along with pruning.
You should divide and repot the plants every 3 to 4 years when grown in containers.
If they are root bound they can become unhappy and quite blooming.

I have had thriving stands of Shasta Daisies for years, and have divided and planted them elsewhere, and they thrived there as well. Last year, they began to die out. After blooming, the stalk and roots died. Some other daisies are also affected. What is going on and what can I do to keep all of the daisies from dying?
The symptoms you describe could be caused by watering problem, either overwatering or underwatering. But since you have grown daisies for years and never had this problem before, and since multiple types of daisies are affected, this seems more likely to be a disease.
Look over this list of daisy diseases from the University of California:
http://ipm.ucanr.edu/PMG/r280112711.html
It looks like Acremonium wilt or Cottony rot may fit your plants' symptoms. In this case you may not be able to grow daisies in that same spot for several years.
Since different diseases are present in different regions, you should check with a local university extension agent or do some research on daisy diseases present in your area.
