It's worth dividing the flower tube every year. This method is considered the most common way to propagate the plant. But what needs to be taken into account?

How do you divide a flower tube (canna) properly?
To divide the flower cane (canna), you should dig up the rhizomes in spring, free them from soil, cut them into sections with 1-3 eyes and place the pieces in well-loosened, nutrient-rich soil in a sunny, warm and wind-protected location plants.
Why share the flower tube?
Basically, it is advisable to divide Canna every two to three years. On the one hand, division strengthens the plant. On the other hand, sharing serves to multiply. This saves costs. The only disadvantage: With this method, no new varieties can be obtained, unlike sowing.
Step 1: Dig up rhizomes and remove soil
After you have brought the canna rhizomes over the winter undamaged, you can divide them. This is best done in the spring before planting. Remove or dig the rhizomes from their wintering quarters. Then clean them of enough soil so that you can clearly see all parts.
Step 2: Divide rhizomes
The next step is to choose a suitable tool for dividing the rhizomes. Suitable tools include a spade, a sharp knife or a saw. Before the tool is used, it should be cleaned orif necessary disinfected. This will kill any pathogens that may be stuck on it.
Now the long rhizome is cut. Pieces should be created that have at least one and a maximum of three eyes. The eyes are the parts that stand out with their elongated-pointed shape and pink color. Finally, unusable parts that have arisen are sorted out.
Step 3: Plant rhizome sections
The newly obtained sections of the rhizomes must be planted. The soil when planting should be well loosened, light and nutrient-rich. A suitable location for the new rhizomes looks like this:
- sunny to full sun location
- sheltered from the wind
- warm
- high humidity
Tips & Tricks
Canna rhizomes are usually extremely robust. Alternatively, they can be divided in the fall. However, this is less recommended as the rhizomes continue to suck nutrients from the leaves until late autumn.
