I just received my summer phlox. And there the bare root. I was wondering and I live in Loveland Colorado when is a good time to plant them? It says they are a late to summer bloom. Thank you Christina
Now is about the time to plant them! As long as the ground is workable.
Here is an article to help you to care for the plant:

Large mounds....years old...added Bloom Booster early spring....still very few blossoms...did cold weather hurt them?
You are in hardiness zone 6 so the cold winter should not have affected it. (generally hardy to zone 3)
Shaving the mound to remove some of the older, woody growth should help with the flowering (you can mow it on high setting after flowering). Also, there are two types of low growing phlox, p. subulata and p. stolonifera, and the subulata type requires full sun to perform well. The other blooms in part shade or sun.
Repeated bouts of powdery mildew can weaken the plants and reduce flowering. Full sun and good air circulation decreases the chance for such fungal diseases.

Will be in mostly shaded
You can grow phlox in pots, but it prefers full sun.
There are many phlox types, the perennial summer phlox, an annual summer phlox, plus a spring-blooming perennial creeping phlox. There also is a woodland phlox, which is most often found at native plant nurseries, that is at home in part shade areas or dappled shade. It blooms in spring.
You most likely are referring to the summer garden phlox. It gets tall, so use a tallish container.

I have white phlox in a pot on my patio. The leaves have developed white spots on its leaves and some leaves have turned yellow. It looks very unhealthy.
Unfortunately, your photo did not come through.
It sounds like, either, powdery mildew or downy mildew. Here are some articles that will help:

I have two phlox plants that are roughly 4-5 ft apart. One looks amazing and the other is struggling, but I'm not sure why. Pictures are attached.
This would be Verticillium Wilt! This is unfortunate. Here is an article that will explain in detail:

eral years. I bought it from a reputable nursery because it was Orange!! What does it need to actually flowre?
Test your soil for nutrient deficiency, or overload. This can be caused by high nitrogen, or lack of phosphorus and potassium. It can also be caused by pH swings, or imbalances.

The varieties I have are Flame, Bright Eyes, Blue Flame and Minnie Pearl. The Minnie Pearl bloomed 3 weeks ago and seems to be all done.
A few weeks of flowering can be normal in many varieties. Deadheading the flowers should bring on another flush of bloom. If only one has flowered, then I would look at environmental issues. They are very heavy feeders, so if the soil isn't fertile, or they don't get fed often, then this could be the issue. If they do get fed, then it could be a lack of light if they are in a shaded area.
