Blooming requires huge energy; plants need constant new growth to support flowers. Lack of fertilizer is the likely cause of only three weeks of blooms. Regular feeding forces new growth, leading to rebloom. Deadheading spent flowers and seed pods also keeps plant focused on flowering.
Use a slow-release fertilizer (Osmocote, Nursery Special) next spring—coated granules feed all season.
