Exuberant canna in the garden is becoming increasingly popular. By dividing the roots in early spring, this ornamental plant, which originated in India, can be easily propagated.
Propagating a canna by root division is quite promising and is therefore the most commonly used method.
When winter is slowly coming to an end and hesitantly passing its baton to spring, then it's time to plan and organize the flowering splendor for the garden in summer. The decorative canna (Indian flower cane) has become increasingly popular for hobby gardeners in recent years.
It is also very easy to propagate.
Split the roots in spring
In early spring, when temperatures are above freezing, remove the tuber (rhizome) from its dark and cool wintering quarters. The tuber is now carefully divided into pieces, each of which should have one to three budding eyes. Then immediately place the sections in a pot with hand-moistened potting soil. Do not water the fresh tubers just yet.
Too much moisture causes rot
Since there are no roots on the nodules intended for propagation, they only tolerate just enough water to keep their soil from drying out. Without roots, they are not yet able to absorb water themselves, so there is a risk of rotting if they get too wet. The tuber pieces can already be planted out after a short pre-cultivation.
Plant outdoors after a frost period
After planting out, the respective sections of the canna tuber then develop into a new plant. As a rule, this then increases very quickly. However, you should make sure that the canna is only placed outdoors after the frost period. The correct planting depth is at a depth that is two or three times the diameter of the root tuber in question. Half of the growth width of the canna is usually sufficient as a distance between the plants.
