How to Plant Canna Lilies

Canna lilies are a tropical plant named for their large, colourful flowers that resemble orchids. They are a great addition to any garden, and are relatively easy to plant and care for. Here's how to plant canna lilies.

Preparing for Planting

Before planting canna lilies, you need to prepare the soil. Canna lilies prefer rich, well-draining soil, so amend your garden bed by adding compost or well-rotted manure. Make sure the soil is not compacted, as canna lilies do not like wet feet. If your soil is heavy clay or sandy, add gypsum or organic matter to improve its structure. Choose a location that gets full sun or partial shade, as canna lilies need at least 6 hours of sunlight a day.

Planting Canna Lilies

To plant canna lilies, dig a hole that is three times the size of the rhizome (the thick, fleshy root) and twice as deep, so that the top of the rhizome is about 2 inches below the surface of the soil. Place the rhizome in the hole and cover it with soil. Space the rhizomes 1-2 feet apart to allow for proper growth. Water the newly planted canna lilies thoroughly, making sure the water reaches the roots.

Caring for Canna Lilies

Canna lilies need regular watering, especially during dry spells. Water them deeply once a week, making sure the soil stays moist but not waterlogged. Fertilize canna lilies once a month with a balanced fertilizer, or use a slow-release fertilizer at planting time. Deadhead the flowers regularly to promote new growth and prevent self-seeding. Cut back the foliage in the fall after the first frost, and cover the area with a layer of mulch to protect the rhizomes from frost damage.

Troubleshooting

Canna lilies are relatively disease and pest free, but they can suffer from root rot if the soil is too wet. To prevent root rot, make sure the soil is well-draining and not waterlogged. If the leaves turn yellow, it may be a sign of too much water or not enough fertilizer. Adjust your watering and fertilizing as needed. If pests like aphids or spider mites appear, spray the canna lilies with a jet of water or use an insecticidal soap.

In conclusion, canna lilies are an easy-to-grow tropical plant that can add beauty to any garden. By following these simple steps, you can enjoy the colourful blooms and lush foliage of canna lilies for years to come.
