When choosing your Mum, it is best to pick one that has not fully bloomed yet. It might be tempting to grab for the Mum with the prettiest blooms, but grabbing the budded plant will give you more time to enjoy it!
If you choose to transplant your Mums, be sure to plant them before the first frost of the season. Next, choose a place with well drained soil, and place your Mum in a spot that will receive around 6 hours of sunlight. After transplanting, make sure you water your Mums often and give them a good soak. Once they are well established, you can water once a week or when your leaves at the bottom begin to wilt. It is important to not fertilize your Mums in the fall so that the blooms are not affected!
