Oklahomans know a thing or two about growing canna. The world’s largest exclusive canna grower, Horn Canna Farm, is a few miles north of Carnegie. Jolene Horn Snow, one of the operators of the farm, claims that you don’t need a green thumb to grow canna in Oklahoma as they are low maintenance and thrive all over the state. You will need to remove the rhizomes in the fall and store them over the winter if you live in the northern part of the state. Plant the canna rhizomes in the Oklahoma garden from mid-March to mid-April.

Determine where you will plant the canna. The plants require full sun, at least four hours per day.

Add a 3-inch layer of well-rotted manure to the planting bed and mix it in to a depth of 8 inches.

Dig holes deep enough so that the canna rhizomes will be covered with 2 inches of soil. When planting more than one canna, space them 12 to 18 inches apart. Drop the canna bulbs into the holes and cover with soil. Canna rhizomes have no top, so it doesn’t matter which end is pointed down.

Water the canna bed to a depth of 6 inches. Water again every week. Keep an eye on the moisture content of the soil on particularly warm, dry summer days in Oklahoma. If it appears to be drying out, water more frequently.

Plant Canna Lily Seeds

Pick each seed up with a pair of needle-nose pliers and rub a metal nail file against the outer coat of the canna seed. Scarification increases the germination rate of the seed. Do not cut too deeply into the seed. Soak the seeds either overnight or for a couple of days. Fill a seed tray with commercial seed starter soil mix. Mist the soil with room-temperature water in a spray bottle. Keep the soil moist while the seeds are germinating, which should be in seven to 14 days. Scoop the canna seedlings out of the soil with a large spoon when they are large enough to handle. Transplant the seedlings into individual 4- to 6-inch plant pots.
