Canna: Start Seeds Indoors or Plant Tender Bulb
How to Sow and Plant
Canna may be grown from seed sown early indoors and transplanted outside after frost, or bulbs planted directly in the garden after frost.
Sowing Seed Indoors:
- Sow indoors in March.
- Plant 1 seed per 12 inch pot or large cell tray 1/4 inch deep in seed starting formula
- Keep the soil moist at 70-75 degrees F
- Seedlings emerge in 7-14 days
- As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
- Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
- Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.
Planting Directly in the Garden:
- Plant bulbs or seedlings outdoors after all danger of frost.
- Choose a location in full sun with rich, well-drained soil.
- Cannas may be planted in the ground or in large containers.
- Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
- Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
- Plant bulbs 1-2 inches deep 15 inches apart. The growing points should be on top.
- Firm soil lightly with your hand, water and keep evenly moist.
- Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
- Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
- Plants need about 1 inch of rain per week during the growing season. Use a rain gauge to check to see if you need to add water. It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
- After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer, as higher rates may encourage root rots.
- Remove spent flower heads to keep plants flowering until fall.
- Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
- Cannas are hardy only in zones 8-10 and should be dug up and stored over the winter in colder areas. Just after the first frost dig about 12 inches from the plant to make sure you do not damage the rhizome, and lift the clump from the ground. Cannas can spread during the season and you will be likely to find considerably larger rhizomes than you planted. Wash off the roots and cut off the foliage. Allow the rhizome to dry and store between 45 and 60 degrees F.
- Cannas add a dramatic tropical look to any garden. Taller cannas make terrific herbaceous hedges, smaller varieties are ideal for containers.
- The flowers are great for cutting.
