[General Plant Care](https://help.costafarms.com/en/knowledge/plant-care?hsLang=en#general-plant-care) # When is the Time to Plant Mums? ## To ensure mums (Chrysanthemums) survive winter, plant them six to eight weeks before the first frost, allowing time for their roots to establish. In Zones 5-7, plant by early September, while warmer zones (8-9) you can plant a bit later. To ensure that mums (Chrysanthemums) survive the winter, it's important to plant them early enough in the fall to allow their roots to establish before the first hard frost. Optimal Planting Time: Six to eight weeks before the first frost is ideal for planting fall mums. This gives them enough time to develop strong roots that will help them overwinter. In Zones 5-7, where winters are colder, plant them by early September. In warmer regions, such as Zone 8 or 9, you can plant them a bit later, but still aim for early fall. Learn what your cold hardiness zone is by entering your zip code into an internet search with the words "cold hardiness zone". Tips for Success: Choose cold hardy varieties: Some mums are bred for decoration rather than survival, so look for varieties labeled as "hardy mums" or "garden mums" instead of "florist mums." Mulch for winter protection: After the first frost, add a layer of mulch (like straw or shredded leaves) to insulate the roots. Water regularly: Ensure they are well-watered until the ground freezes. Don't prune in the fall: Leave the dead stems until spring to provide extra protection to the crown during winter. Planting mums in early fall, rather than waiting until the colder part of the season, helps ensure they'll come back year after year. - [Plant Care](https://help.costafarms.com/en/knowledge/plant-care?hsLang=en#main-content) -
