Answer: There are several types of tall phlox and they are all lovely summer blooming garden plants and they are all treated about the same way. They prefer full sun, good air circulation, and an evenly moist yet well drained and rich soil. You may find it beneficial to thin the emerging bloom stems in spring so as to allow space for good air circulation during the summer. The plants do best on a deeply prepared soil and will appreciate some balanced fertilizer and/or compost in early spring and for border phlox, again in early summer before they bloom. It's a good idea to keep an eye on the watering and mulch these with several inches of organic mulch to help maintain soil moisture since these plants will bloom best with adequate water. Finally, remove spent flowers and in fall do a careful clean up of old stems and foliage, especially if there was any problem with mildew during the growing season. Enjoy your phlox!
