Regularly remove spent flowers throughout the growing season. This not only tidies up the plant but also prevents seed formation, allowing the plant to focus energy on producing more blooms. Trim back any overgrown or leggy stems to maintain the plant's compact shape. This is best done with sharp, clean shears to minimize plant stress and the risk of disease. If the plant has grown unevenly, carefully prune to maintain an even, round shape. This can be particularly aesthetic in border plantings and will promote even development of new growth.
