They will also grow equally well in large containers that can be brought inside during the dormant period.

Gardeners in these regions can either treat cannas as annuals, discarding them after the season, or dig up and store the bulbs for replanting in spring.Cover the rhizome with one to two inches of soil. Cannas are slow to sprout and do not require much water until you begin seeing signs of growth. Sometimes is takes as many as three weeks for cannas to sprout. Once sprouted, water cannas at least once a week by slowly soaking the area around the roots.Soaking canna bulbs before planting is a simple, effective way to ensure your tropical garden gets off to a fast and healthy start. By taking a few hours to rehydrate the rhizomes, you are setting the stage for more vigorous growth and earlier blooms.

Cutting Back Lilies For Winter To cut back lilies, use sharp scissors or pruning shears to remove the spent foliage. Cut back the foliage to the base of the plant, as this will prepare the plant for new growth in the spring. Lilies grow from bulbs and naturally propagate themselves by creating new bulbs, but you can help speed up the process. Dividing lilies is good for the plants because the bulbs will multiply underground without your intervention and eventually overcrowd themselves.
