Every year I seem to get this on my plants and it seems to stop them from flowering like they should. What is the best thing to buy or some homemade remedy?

Every year I try to grow it the same, but they end up dried and dead. What is the secret to make them flourish?
The biggest thing about these plants is they need great drainage. If your soil is clay heavy or has poor drainage, you may want to try amending it before planting this plant there.
I have a butterfly garden that has gotten out of control. How do I tame it? My butterfly garden contains Garden Phlox, Beard Tongue, Bee Balm, Butterfly bush, Mouse-ear Thickseed, Everlasting, Showy Stonecrop and Shasta Daisy. These plants are planted in the required 4' x 6' raised bed per instructions of the company I purchased the garden collection from. Now all of the plants are overgrown (have only been planted a little over a year) and falling over with heavy blooms. What can I do to save this garden and make it look nice again?
A bit of pruning may be in order. Prune the tops of plants. Using a sharp pair of scissors or pruning shears, trim away any old growth, characterized by woody and sparse leaves. This growth may be tough to cut, so be careful. Next, remove any sickly growth on the overgrown plants, which is often characterized by yellow leaves or a wilted appearance. Be sure to leave any new, tender growth alone.
My phlox has not bloomed yet. It gets sun until 2:00 pm. What am I doing wrong?
Phlox are kind of late bloomers. Do you see them blooming in other yards?
I have had 4 Phlox plants for several years and they rarely bloom. I have tried moving them but it has not made a difference. They also get a fungus every summer that I have tried treating with antifungal sprays. I see many beautiful Phlox blossoming as I drive and would love for mine to do they same. I live in Zone 4. Please help.
You may be lacking phosphorus. If there is a lack of phosphorus in the soil, plants will have little to no blooms. You can either use a phosphorus rich fertilizer or add some bone meal to the soil.

What temperature to plant? It is supposed to get to freezing tonight. Is this too cold to plant now?
This has been a very unusual winter for sure, unseasonably mild most everywhere, and now the onset of frost and freeze is threatening many of the plants that have set buds or blooms. While it's a fairly hardy plant (cold hardy to zone 3), I would certainly wait until the threat of freezing temps have ceased before planting creeping phlox.

Will phlox overtake other plants and flowers already planted?
No, it shouldn't. Phlox is not usually considered to be aggresive.
