Where is the best place to plant cannas?
The Canna bulbs should be planted in a location where the soil drains well. Unlike most bulbs, cannas can thrive in moist soils but will not tolerate standing in water puddles.

Cut plants back to 4 inches in late autumn to prepare for next summer’s show. After the first autumn frost kills the foliage, you can remove the stems and leaves. See your local frost dates. In the deep South of the U.S., let cannas grow without moving them until the clumps grow very matted.
Do cannas come back every year?
In frost-free areas of the climate range, canna plants grow year-round without the annual winter die back experienced in colder areas. Throughout the growing season, flower stalks die back after the flowers go to seed. To prolong flowering, clip off each flower as it starts to fade before it sets seed.
What month do you plant cannas?

Do cannas like sun or shade?
They are thirsty plants and need a consistent supply of water throughout the growing season. In warm areas, cannas grow well in full sun or in partial shade. In cooler areas they grow best in full sun. Rhizomes should be planted horizontally, 2 to 3” deep and 1 to 2 feet apart.
Can cannas take wind?
Cannas do not need staking, but if they are planted in a windy, exposed area, the leaves can be shredded. Providing shelter from wind is always a good idea. This prevents the plant from setting seed and encourages new stems to grow and bloom – which they will do right up to a hard freeze.
Do cannas multiply?
Canna flowers are not true lilies and their root structures are more like irises than lilies. Like iris plants, canna rhizomes multiply quickly and eventually older rhizomes in the center of the mass can be choked out. Dividing perennial grown cannas every 3-5 years will keep them growing in smaller healthier clumps.
How do you keep cannas blooming?
To keep your plants flowering throughout the season, deadhead them as the blooms start to fade. If you prefer to grow cannas for their foliage alone, you can cut back the flower stalks before they even have a chance to bloom.
