General Information:
Cannas, also known as Canna lilies, are tropical plants that are native to South America. They are prized for their vibrant and showy flowers, which come in a wide range of colors including red, orange, yellow, and pink. Cannas are known for their large, lush foliage and can grow up to 6 feet tall and do well in garden beds or as a focal point in large containers.
Choosing the Right Location
When it comes to growing cannas, choosing the right location is crucial. These plants thrive in full sun, so make sure to select a spot in your garden that receives at least 6-8 hours of direct sunlight each day. Cannas also prefer well-drained soil, so ensure that the area has good drainage to prevent waterlogging.
Planting and Care
- Prepare the soil: Before planting, prepare the soil by loosening it with a garden fork or tiller or if planting in a container, fill container with aerable soilless mix. Add organic matter such as compost or well-rotted manure to improve the soil's fertility if planting in a garden bed.
- Planting: Dig a hole that is about 4-6 inches deep and place the rhizome (the thick, fleshy root) horizontally in the hole and with the green leaves up.. Cover it with soil and gently firm it down.
- Watering: Cannas require regular watering, especially during dry periods. Keep the soil evenly moist, but avoid overwatering as it can lead to root rot.
- Fertilizing: Apply a balanced fertilizer, such as a 10-10-10 or 14-14-14 formula, every 2-3 weeks during the growing season to promote healthy growth and abundant blooms. Or add slow release 3-4 month fertilizer to the soil mix.
- Deadheading: Remove faded flowers regularly to encourage continuous blooming.
Overwintering Cannas
In our area with our cold winters, cannas need to be protected during the dormant season if you would like to keep them for next year. Here's how to overwinter your cannas:
- Trimming: After the first frost, cut back the foliage to about 4-6 inches above the ground.
- Digging: Carefully dig up the rhizomes, taking care not to damage them. Shake off excess soil and allow them to dry for a few days.
- Storage: Store the rhizomes in a cool, dry place such as a basement or garage. Place them in a container filled with peat moss or vermiculite to prevent them from drying out.
- Replanting: In spring, when the danger of frost has passed, replant the rhizomes in the garden following the planting instructions mentioned earlier.
