Large potted mums
Yes, you can winter over mums in their pots. Cut them back to about 1" above the soil line and put them in a cool dark space (32 to 50 degrees). Water 2-3 times a month (soil should feel just slightly moist). Stick your finger down in the pot, if it feels dry 1 to 2 inches down it is time to water lightly again. Put them out in the spring past last frost, fertilize and water and they should return.
