To get a jumpstart on tropical blooms and foliage, many Northern gardeners will start canna rhizomes indoors about four weeks before transplanting them to the garden.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.For planting in pots, fill a large pot to within six inches of the top with a well-draining potting mix into which you have added a little peat moss and perlite.

During the hottest weeks of the summer, give the plants a good soaking drink of water every other day.Plant your Canna Lily rhizomes outdoors from late spring to early summer after the danger of frost has passed. They can also be started indoors in pots as early as a month before the average last frost date for those with shorter growing seasons.Understanding Canna Plants There are two primary methods for overwintering Canna plants: storing the entire pot in a frost-free area or lifting and storing the rhizomes (the underground stems).Enhancing growth: soaking Canna bulbs Soaking allows the bulbs to absorb moisture, kickstarting their internal processes for robust growth. Begin by placing the bulbs in lukewarm water for a few hours. This hydrates and activates the bulbs, giving them a head start for successful planting.
Can you plant canna bulbs in the fall?
When to Plant. Plant your Canna Lily rhizomes outdoors from late spring to early summer after the danger of frost has passed. They can also be started indoors in pots as early as a month before the average last frost date for those with shorter growing seasons.

The plant will go dormant and may be revived the following spring after spring frost.
