#ProPlantTips for Care:
Garden Phlox does best when planted in a full-to-partial sun area in well-drained soil. These herbaceous perennial Phlox thrive in enriched, moist soil and a 3-4 inch thick layer of mulch for best results. Water at the roots and keep your plants evenly moist.
Deadhead after the flowers fade to encourage a rebloom, then prune your Phlox back in late autumn after frost has reduced these herbaceous perennials down for the year. Prune Tall Phlox right after the blossoms fade and tidy up the mounds in late autumn after frost. While no plant is truly deer resistant, they do not prefer the taste of these plants. Every 3-5 years, it's recommended to divide your clumps to maintain vigor and provide you with extra plants to expand your enjoyment. If you live in high Deer pressure areas, be sure to use Deer Repellent during planting, guided by the instructions on the label.
