#ProPlantTips for Care:
Emerald Blue Creeping Phlox needs to be planted in a full sun area in well-drained soil for the best growth possible. Provide moderate yet consistent moisture for new plants their first year, but after, these plants are very self-sufficient. Provide moisture during times of drought and extreme heat, and to further help with moisture retention, add a 3-4 inch thick layer of mulch over the soil surface. Prune/shear mounds immediately after flowering and remove up to a third of the top growth for a clean start.
- Full Sun
- Well-Drained Enriched Soil
- Moderate Moisture
- Prune After Flowering
