Deadheading is an important step when caring for Monarda Petite Delight perennials. Deadheading is when you remove dead or spent flowers from your plant to make room for new growth. Instead of having your plant focus its energy on dead or dying flowers, remove them so your plant can focus on producing beautiful and healthy blossoms. This plant is fast-growing and spreads quickly, so you should divide it every 2 to 3 years.
