Prefers moist, humus-rich soil. Phlox can be divided every 3 - 5 years in spring or fall. Self sows prolifically but colors may not grow true to parent plant. Cut back by 1/2 in late spring/early summer to encourage more compact plants. Shear off after bloom, just above foliage to encourage more blooms. Snip off any winter-damaged shoots in spring. To allow for good air circulation, snip out all but 4 - 6 stems in mature clump.
