How deep do you plant canna bulbs?

Where is the best place to plant cannas?
Select The Right Site Best flowering occurs in full sun in organically rich, moist and well-drained soils. Canna lilies will survive in the shade but best flower production is obtained in full sun – except in hotter climates where part shade will enable the flowers to last longer.
Do cannas have deep roots?
Cannas tolerate most growing conditions. Starting them indoors will speed up blooming time; planting outdoors too early will delay flowering and possibly rot the rhizomes. Plant roots 12”-18” apart and 3”-4” deep. (Roots should have 3-5 eyes; the more eyes – the more flower stems!).

Should I soak canna bulbs before planting?

How do you keep cannas blooming?
For best blooms, plant cannas in full sun, water regularly and fertilize plants 2-3 times throughout the growing season with a general 10-10-10 fertilizer. The most common reason for no flowers on a canna plant is overcrowding. When grown as perennials, canna lilies will grow and spread very quickly.
Which way do you plant canna bulbs?

Do canna lilies need full sun?
Light: Cannas need full sun to reach their flowering potential. Shade encourages leggy growth that can cause foliage to flop over. Plants in shade won’t produce as many flowers, either. Several varieties are grown for their colorful leaves, which are not as bright in the shade.
How often do you water cannas?
