Interesting Facts

Regulations for cleaner waste water at plant nurseries are getting tighter. To accommodate these regulations, many growers are now capturing the irrigation solution after it has passed through the growing media of the plants that they are growing for reuse. Before the water can be used again, the water must be cleaned. Many of these growers are planting Canna Lilies in their irrigation water return ditches. The Canna Lilies can withstand variable fertilizer concentrations and will remove some of the salts out of the irrigation solution resulting in cleaner water. Not only do the plants offer a service of "willingly" filtering recycled irrigation water, but they also produce beautiful flowers that can be harvested for cut-flowers. Canna Lilies aren't actually lilies. They are more closely related to plants such as the Bird of Paradise and true gingers. The name Canna is derived from the Celtic term that translates to "cane" in English.

Plant Care
Planting:

Plant rhizomes in rich soil about 4 inches deep and 2 ft. away from other planted rhizomes. Every 4 years divide clumped rhizomes.

Plant Growth:

Cannas are best adapted to warm or hot climates. In areas where the ground freezes, the rhizomes can be dug out of the ground and moved indoors until threat of frost has passed. If the climate in the winter hovers around freezing, a thick layer of mulch over the underground rhizomes may provide enough protection from the cold.

Blooming:

Many different types of flower colors including red, orange, yellow, pink, cream and white. Cannas flower in summer and autumn. Deadhead to prolong flowering.

Soil and Irrigation:

Requires regular water during growth and bloom. Canna Lilies can withstand a surprisingly large quantity of pollutants and are readily adaptable to most soils.

Fertilization:

When freely growing, apply a phosphate-rich fertilizer once per month.

Pruning:

As winter approaches the foliage will die back. Prune the leaves to about 2" above the ground. Canna Lilies that have been well established may begin to crowd themselves. In the spring, thin out the rhizomes to provide more space for growth and aeration in the soil.

Pests:

Although Cannas are mostly free from pests, there are specific insects that have an affinity for these plants. The Canna Leaf Roller is so named for its affinity for the Canna Lily. Slugs and snails can leave holes in the Canna's rather large foliage. The flowers are subject to Botrytis if left in exceedingly humid conditions.
