You will quickly find joy in these uncomplicated tropical plants. Whether it's the leaves, which can be green, dark red or blue-green, or the colorful flowers - the flower cane is visually appealing. Therefore, it is worth propagating it with your own hands.
Growing canna from seed
If you don't want to buy the seeds, you can take them from the plant's three-compartment capsules in late autumn. They are small, dark brown to black in color, hard-shelled and vaguely reminiscent of pearls. They can be sown immediately after ripening. They should be set to germinate by mid-February at the latest.
Before sowing
Take the seeds and clamp them firmly between your fingers, in a vice or between needle nose pliers. Now sand the seeds with sandpaper. Alternatively, you can use a nail file to gently file down the hard shell. Once you see the white inside, stop. It is important not to damage the seeds.
After grinding or filing, the seeds are brought to swell in water. A bowl of warm water will do the trick. The seeds are soaked in it for 48 hours. Then, as a rule, the beginnings of the seedlings have come to light.
Plant seedlings in the ground
How to proceed:
- choose small growing pots (16.68€) (8 to 10 cm).
- Fill pots with nutrient-poor, light soil
- Insert seedlings
- Water the soil and keep it moist afterwards
- place on a window sill above a heater (as an example location)
- after 6 to 14 days the first cotyledons appear
- Transplant young plants after the last frost
sharing cana
The rhizomes of the flower cane can be divided in spring before planting. Dividing canna is considered the most common and least laborious method of propagation.
Divide the rhizome so that there are one to three eyes per section. A spade or a sharp knife can be used, for example. After dividing, the rhizomes can be prodded before planting at home.
tips and tricks
Get the young plants used to the sun slowly, otherwise they will get sunburned.
