We planted this about 6 weeks ago and it bloomed already and looked nice. We dead headed after it bloomed. Now the leaves are turning brown.
This will be transplant shock from planting during the Summer. These will be best planted in Spring or early Autumn.
From here, proper care will ensure a good recovery, but it may not look too healthy until next year.

images I can find online. But it is a pretty pest I need to control . Many thanks in anticipation of your response. I have attached a photo. Matt from Kent.
No. It looks like a variety of garden phlox. You could probably find people who would take that off your hands. It's a good pollinator plant for bees, butterflies, and hummingbirds.
You can dig it up to eliminate it or spray with herbicide, or douse it with boiling water. There is an old fashioned garden phlox that is invasive but it is very tall, at least 3 feet. Maybe it's just the angle of the photo but yours doesn't look that tall. I have had to take radical measures with it before.
If you have a corner of your yard where it could run rampant, it could be moved there.

Powdery mildew arrives on phlox every year. What can I put on my beds to destroy the spores after the garden has been chopped down and raked in the fall? The lilyleaf beetle has devastated by oriental and Asiatic lilies. Is there a solution that doesn't require toxic chemicals? I have densely planted cottage gardens and the pick and destroy method becomes overwhelming. Thank you.
Be sure when you rake the fall debris you get it all picked up. The spores remain on leaves that are left on the ground. Here are articles with various remedies that may solve your problem:

How long does it take for garden phlox to bloom a second time after dead-heading first bloom? Which perennials will have enough time for a second bloom in the zone 6 Ontario growing season?
This depends on the cultivar, but they will usually bloom by this time if they were deadheaded as soon as flowering stopped the first time around. If it is not blooming by now in your area, you may not see a second bloom this year.
Unfortunately, there will be too many plants to list here, but this article will give you a good idea of what plants will do well in zone 6:

It's a phlox and it has some live branches as they passed the scratch test but the main stem failed the test. Can I save it ? Thanks anyway .
The soil looks heavy. You can try repotting it in a lighter soil, give it some light fertilizer, and water when the soil is dry. It may get too hot in your climate to grow these.

The leaves are dried up to the top, the flowers are pretty much done. Is it too soon to cut all the down? We have had 90+ weather for 4-5 weeks. Thank you for your help!
Yes, you can cut it all down. You may get new growth before the season ends.
I planted phlox, asters stocks and daisies
I hope your seedlings survived! They look like they need more light. Also, a fungal disease, called damping off, can cause the collapse of seedlings. These articles should help with your seedlings.
