Comments: 
Phlox are flashy, gorgeous plants that are reliable mainstay in many gardens. Garden phlox are intolerant of drought and wilt rapidly. Avoid placing under trees or overhangs as they are prone to powdery mildew, which is encouraged by dry soil and wet foliage. To learn more about powdery mildew click here. 

Phlox benefit from being mulched, which holds moisture in and keeps the soil cool. 
Deadhead spent flowers for a repeat bloom and to prevent their seeds from unwanted self-seeding. Their seeds revert to the species which grow with vigor.
​

To prevent overwintering diseases, cut back plants to the ground and remove any of their leaf litter.

If deadheaded soon after their flowers fade, they may blossom again in fall, like this fine specimen.
