Nothing beats colorful creeping phlox as a perennial spring ground cover. While each plant grows to only about 6-8 inches tall, it will form a dense 12-24 inch carpet that never runs amok or gets out of control. Providing 6 weeks of continual masses of lavender, pink, white or bicolor beauty, these tough little plants are not demanding and present no disease or pest issues. The icing on the cake is the lovely foliage that continues to adorn gardens and landscapes even through the winter, when most plants shed leaves and retreat into dormancy.
Select a new home for your creeping phlox plant in partial or full shade. The soil should be well drained, but rich and capable of sustaining moisture reasonably well.
Dig a hole a little wider and equal in depth as the plant’s current container.
Position the creeping phlox in the hole so that it will be planted at exactly the same depth that it occupied in its nursery container. Fill the hole halfway with water and allow it to seep into the ground. Backfill the hole with original soil, pressing it firmly to the plant.
Water enough to moisten the soil, and mulch lightly if you wish. Water the plant as needed thereafter, keeping it uniformly moist but not wet or soggy.
Feed your creeping phlox a healthy dose of compost one time only in the spring. Over-fertilizing these plants causes excessively abundant new growth, which is subject to severe burning during the winter.
Perk up and refresh your creeping phlox by pruning out older dead stems after a year or so if it begins looking a little unkempt. You can also trim the entire plant back about 1 inch after your phlox has finished blooming. This will produce bushier growth and increased flower production for the following spring.
