Beautiful phlox fills garden beds with large quantities of pink, purple and blue flowers. Whether you have creeping phlox or a taller variety, you'll want to keep phlox flowering for as long as possible each season and have it continue year after year. Regular watering and fertilizer applications will make your phlox the envy of the neighborhood.
Plant phlox in an area where it will receive at least six hours of direct sunlight each day.
Apply a flowering plant fertilizer when new growth starts each spring following the directions on the packaging. Repeat application each month during the growing season.
Water your phlox weekly to keep the soil moist over the spring, summer and fall. Avoid wetting the leaves and stems when watering to lower the risk of disease.
Add a 2 to 3-inch-deep layer of mulch around the base of your phlox plants using bark mulch, compost or pine needles. Spread the mulch 1 foot beyond the base of the plant to keep weeds away and retain the moisture in the soil.
Dig up your phlox in the early winter if it has been four to five years since it was planted and divide the body of the plant into three or four divisions. Plant each division out into a new spot, keeping the plants at least 18 to 24 inches apart to allow room for growth.
