How do I prevent my white mums from changing to light purple?

I planted them as white blooming plants this fall and now they are turning purple. Every time I plant white mums they change. What am I doing wrong?

    You're not doing anything wrong.. I've had white mums all my life (and I'm old). As they age, they pink or purple up.. yes, I'd like them to stay white, but we are not doing anything wrong..

    Check with your local nursery about ph soil factor. Maybe there is something you can add to the soil. I've seen mums turn colors, so I'm not positive, but hope everything works out for you. Best of luck.

    I have a bunch of them, they get very big now after a couple years ..... but they all have turned light purple.

    This year I am keeping them in bigger pots, and burying the entire plastic pot to keep the soil/Ph intact .... maybe that will keep the colors the way I bought them

    Hello, hope this helps you out, Some mums change colors that way naturally as the blossoms age.

    All newly planted mums require careful attention to soil preparation and watering or they may wilt. This is especially true, however, with those that are very potbound when purchased. In some cases, too, they are used to daily watering at the gorwers and it is difficult for them to adjust to growing under garden conditions.

    For the above reasons some people consider mums to be the equivalent of cut flowers -- a pretty but ephemeral decoration. If you are planning to grow them as perennials your best bet is to purchase them as early in the season as possible (spring is best if you can find them) so they can become well established before undergoing the stresses of blooming and winter weather.
