The name 'Phlox' is derived from the Greek word meaning flame in reference to the intense flower colors.

Caring For Phlox

Fertilize garden phlox in early spring. Spread granular all purpose fertilizer around the base of the plant, following package directions. Top dressing the plants with a couple inches of compost will add nutrients and help improve the soil.

After the flowers have faded, cutting off the spent flower heads will often promote a second flush of flowers. It also keeps the plants from self-sowing (volunteer seedlings will be inferior to the parent plant and should be treated as weeds). In the fall, cut back all stems to the ground and remove them from the area to help minimize future disease problems.

When garden phlox becomes overcrowded, flower production starts to decrease. To maintain a good show of flowers, you may need to divide the plants every 3 to 4 years. As long as the plants continue to flower well, there’s no hurry to divide them.

Important Note

The common names for Phlox species are very confusing. Different species may be called by the very same names. Please be sure to check the species name when ordering plants to be sure you are purchasing the type of Phlox you want!
