Reduce watering slightly during winter dormancy.
Deadhead spent flowers to encourage continuous blooming and maintain a tidy appearance. Cut back the entire plant by about one-third in late autumn or early spring to promote new, vigorous growth.
Remove any dead or damaged stems at any time.
Division is the most common method. In early spring or autumn, carefully divide overgrown clumps, ensuring each section has roots and shoots.
Alternatively, take basal stem cuttings in late spring and root them in moist potting mix.
Container-grown Dotted Loosestrife benefits from repotting every 2-3 years. Choose a pot that is one size larger than the current one.
Repot in spring, using fresh, well-draining potting mix to refresh nutrients and provide more space for root development.
