The shasta daisies and daylilies in my flower bed are about 4 years old. They started out fine this year, but during the past few weeks most of the flowers on them have died. The foliage still looks okay. This week I noticed that the flowers on the tickseed in the same bed have started dying. I water at least once a week. Why is this happening and how can I stop it? Thank you for any help you can offer.
If the summer heat has hit you may need to increase watering.
Have you inspected the plants for insects or disease?
You may want to treat with Neem Oil as if works as a insecticide and fungicide.
Last summer I picked up a leucanthemum at Home Depot toward the end of the season. There were three plants in the container. I separated them, transferred one to a larger pot, and planted the other two in the ground. All three returned this summer with abundant foliage, but no flowers. NONE! What happened?
Most likely to much Nitrogen in the soil.
You can add Phosphorous which will promote flowering.
Bone Meal is a good way to do that.

I am zone 6. I have had a potted Shasta Daisy on my deck for 3 seasons. I leave it out all winter. Last year it bloomed beautifully. This year while it started off ok, stems growing and full, it is not blooming and the leaves are all now yellowing and droopy. It looks like it is dying. I am not doing anything differently. Any ideas?
Yellow leaves can happen for a number of reasons, but in your case I am wondering when you fertilized last? I think they may be getting too much nitrogen. This can cause explosive growth at the beginning with few to no flowers and eventually causes the plants to yellow and start to die.
If you have not fertilized, then underwatering, lack of nutrients or a fungus are to blame, likely. Increase water a bit, use a balanced fertilizer on the plant and treat it with a fungicide. This should take care of the most common causes of yellowing.

I have an overgrown perennial garden, and some of the shasta daisy clumps have a problem with their lower leaves drying out and becoming dry and brittle. Is this a fungus or blight? Should I plant in this soil if such an issue exists?
This is likely just the aging of the plants.
Shasta Daisy is very forgiving and you can cut back and prune quite aggressively.
This is not indication of your the health of your soil. A soil test is always a good idea in a new garden or a garden that has been neglected.
This will help you take the guesswork out of fertilizing and soil amendments needed.
I have several areas of shasta daisies. They start out looking great but about a month into growing they start falling to the sides and some in the middle die. Now when I look in the center of the area, there are the stems with the heads of the daisies having fallen out to the sides so that there is a large bare circular area in the center.
This normally happens because the plant do not get quite enough sunlight and they have weak stems. If you can get them more light, that would be helpful.
You may also have an animal bedding down in the flowers at night. This will create a circular pattern of flattened plants and kill the plants in the center.
You likely have to much Nitrogen in the soil.
This causes lush green plants and little to no flowers.
Adding Phosphorous is a remedy and Bone Meal is great way to do this.
