Well-branched stems and an upright, mounded growth habit give this looker a full and dense appearance. Plant in beds or borders where this perennial will add intense color. Feature in a container to enjoy this lovely Phlox on a porch or patio space. This is a low-maintenance perennial in USDA zones 4 through 9.
Ka-Pow® Purple Garden Phlox Care
Phlox thrives in full sun and fertile soil that is moist and well-drained. New plants need consistent water for the first growing season. Older plants need water once per week or when the top few inches of soil are dry. Keep the foliage dry and water the soil around the plant to reduce the risk of fungus.
Consistent fertilization each spring using balanced plant food will keep this stunner happy and healthy. Phlox are prone to becoming leggy, so trim back growth in late spring or early summer to keep the plant contained and bushy. Remove spent flowers to encourage more blooms. Propagate this clump-forming plant via division every few years.
