Answer: If you have purchased a hardy variety of mum they should live if planted outside. They need to be planted early in the fall so they have time to become established before the cold winter hits. They also need a location with very good drainage, meaning not soggy over winter. Finally, they do best in a rich soil in full sun. After the blooms fade, trim them back to about four inches and mulch around them but not over them with several inches of organic mulch. Be sure to water them well at planting and to keep the soil slightly moist until the ground freezes.
