canna

Canna should be watered regularly and generously. In general, water the plant whenever the soil dries out, which is usually once or twice a week during the growing season. Allow the soil to dry out a bit between waterings, then water thoroughly until moisture runs out from the bottom of the pot. Reduce the amount of water in the winter months when the plant is not actively growing.

Canna plants thrive in full sun and a minimum of 6 hours of direct sunlight is recommended to optimize robust growth and blooming. Canna plants can tolerate partial or dappled shade, however, they will usually produce fewer flowers when grown in these conditions. It is best to provide as much direct sunlight as possible during peak hours of the day, typically between the hours of 10 a.m. and 4 p.m. Avoid planting canna in areas that receive heavy afternoon shade, as too much shade can weaken the flowering potential of the plant.

Canna plants should typically be pruned in early spring, just before the new growth appears. Pruning should focus on dead or damaged foliage as well as removing any unwelcomed sucker growth. Remove no more than 1/3 of the plant in 1 pruning session. Additionally, removing any existing blooms will result in larger and more numerous blooms in subsequent years.
