Phlox

10 Gardening Tips

1. Dividing the phlox every 3-5 years will help to reinvigorate the plant and improve garden performance.
2. With Tall Garden Phlox and other summer-blooming types, keep plants well-spaced to reduce issues with mildew.
3. Avoid overhead watering unless the plants will have a chance to dry out. An excess of moisture will increase the likelihood of powdery mildew.
4. Sandy loam is the preferred soil for all species, as it provides the good drainage these plants need to thrive.
5. More sun means more garden performance, both with increased floral production and sturdier, healthier habits.
6. Tall Garden plants thrive in rich soils and can be fertilized every other month if nutrition is a concern.
7. Deadheading Tall Garden plants will prolong the bloom time and prevent self-seeding.
8. Trim and clean up any dead foliage on your Creeping Phlox in early summer, just after they have finished blooming.
9. Fall is the best time to divide and replant Phlox.
10. Some species of Creeping Phlox are evergreen. On these plants, winter dieback should be cleaned up in spring, or early summer after they have finished blooming.
