Phlox seeds planting instructions

Rich, loose well-drained soil

Phlox seeds can either be planted straight into a flowerbed or seeded indoors and then transplanted later. Plant your phlox seeds in rich, loose, well-draining soil. If necessary, you can add peat moss or perlite to improve drainage. Add a general purpose fertilizer when planting phlox seeds, then continue to do so once a month.

Water generously

After planting your phlox seeds, water them generously. Once your phlox are growing, keep the soil moist to slightly dry. During dry periods, water phlox once or twice a week.

Full sun

Phlox prefer full sun, but will tolerate light shade. Too much shade will result in a tall but scrawny plant. Phlox will benefit from being grown in a well-ventilated location, as this will help to combat powdery mildew. If necessary, you can treat them with fungicide. You should space phlox around 8 to 10 inches apart.

Phlox maintenance instructions

Remove worn-out blooms to encourage new flowers and lengthen the blooming period. Deadheading will also improve the appearance of your phlox. In late autumn, your phlox should survive a few light frosts, but the foliage will soon fade and wilt. When this happens, clip the stems down to 2 inches off the ground. Your phlox will then resurface in the spring.
Hardy phlox will spread and develop into large clumps over time. These clumps can be divided by cutting them in half with a sharp shovel. The resulting pieces can then be replanted elsewhere in the garden, or shared with friends. You can divide them in the autumn every 3 or 4 years.
