Quickly find pleasure in these uncomplicated tropical plants. Whether the leaves, which can be green, dark red or blue-green, or colorful flowers – flower cane is visually appealing. Therefore, it is worth to propagate it with their own hands.
Canna grow from seed
If you don’t want to buy the seeds, you can take them out of the plant’s trifoliate capsules in late fall. They are small, dark brown to black in color, hard-shelled and remotely resemble pearls. Immediately after ripening, they can be sown. By mid-February at the latest, they should be set for germination.
Before sowing
Take the seeds and clamp them tightly 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 carefully file off the hard shell. Once you can see the white inside, stop. It is important not to damage the seed plants.
After grinding or filing, soak the seeds in water to swell them. 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 seedlings emerged.
Put seedlings in the ground
Proceed as follows:
- choose small seedling pots (7,00€ at Amazon*) (8 to 10 cm)
- Fill pots with nutrient-poor, light soil
- Put the seedlings in
- water the soil and keep it moist for the following time
- place on a windowsill above a heater (as an example location)
- after 6 to 14 days the first cotyledons appear
- plant out seedlings after the last frost
- Divide canna
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, for example, can be used. After dividing, the rhizomes can be pre-sprouted before planting at home.
