florist mums inside in winter?
I am in Nebraska. Have a florist mum that was purchased in spring that has been in a pot all summer. Can it be kept inside in cool area over winter? And what about keeping a garden mum still in the pot over winter?
Keep them growing in containers Geraniums grow easily indoors in containers with proper care and environmental conditions. Before the first frost, cut back plants to half of their original size and inspect them for signs of insects or disease. Then, dig up healthy plants and transplant into containers. Use a potting mix made for containerized plants instead of garden soil. Garden soil is often heavy, compacted, and drains poorly in containers. Place containerized plants in a cool location, 60-65 F, with plenty of bright, direct sunlight. Water plants well after potting and as needed when the soil begins to dry. Shoot tips may need pinching once or twice during the winter to promote branching and prevent weak growth. Before planting outside in May, fertilize lightly. Plants kept in containers over the winter are typically larger than most geraniums sold in the spring. This allows you to have a head start on growth and blooms for next year's garden. Dormant Storage Geraniums are unusual and unlike many annual flowers, they have the ability to survive for most of the winter without soil. If properly stored, they can resist extended dry periods due to their thick, succulent-like stems. To overwinter geraniums in dormant storage, dig up the entire plant before frost and gently shake the soil from the roots. Place the plants inside open paper bags or hang them upside-down from the rafters in a cool, dark location for the winter. Ideally the temperature should be between 45-50 F. Two or three times during the winter, take the plants out the bags or down from the rafters and soak the roots in water for 1 or 2 hours. At this time, inspect the stems. While many of the leaves will die and fall off, the stems should remain firm and solid. Discard any geraniums with shriveled stems, since those plants will most likely die. Pot up healthy dormant geraniums in containers in late March or early April. Water plants thoroughly and cut back the dead stem tips. Place potted plants in a sunny window to initiate new growth. It often takes several weeks for plants to initiate growth after dormant storage. No matter how geraniums have been overwintered, they should be healthy, free-flowering plants for spring. After being indoors all winter, your geraniums may be as anxious as you are for spring planting. Plant them after the danger of frost has passed and enjoy their colorful blooms all summer. You can invest your savings in new geranium varieties to overwinter next year. Either of these techniques could be used with both mums.
