Keep your Igloo mums’ soil moist as winter approaches. There is no need to prune back plants until the following spring. In fact, Yoder Brothers of Barberton, Ohio have proven, by experiment, that mums cut back in early spring, instead of fall, survive hard winters better.
Mulch the plants after several hard frosts with straw or evergreen branches, etc. In spring, remove any old stems (a rake works fine) and gradually remove the mulch.
