Subsequently, question is, when should I trim my mums? As a general rule, the time to prune — or “pinch” — your mums is from spring into the early summer.

How do you keep fall mums alive?
Water Mums from Bottom: Protect your mums from rain, and water them carefully without splashing the foliage or blooms. This will help keep the blooms from spotting and browning. Keep Mums Cool: Warm temperatures also encourage blooming, while cool temperatures will help mums blooms last longer.
