HI, Eric, Your Anthemis tincotoris 'Charme' is here on Shoot and if you add it to your 'Plants I Have' list, you will get complete instructions on how to care for it, including when to cut back. Advice given is to cut back hard after flowering. So, in other words, give it a good, low, even haircut. This will encourage bushy growth. Unless you live in a very warm area with a long growing season, it is unlikely you will get a second bloom. Kathy C.
