Planting and caring for cannas is not that difficult, even if it is a true exotic. We'll tell you how to do it.The canna comes from South America
The Canna, which actually comes from South America, is often also popularly known as Indian flower tube designated. Due to constant breeding changes by gardeners, the absolutely impressive looking canna is now even offered in the garden center with differently colored flowers and green or brown-red leaves.
The flower colors of the perennial cannas range from white, beige, yellow, apricot, orange, to pink, pink, red and dark red and the resulting color nuances. If you want to bring this beautiful flower into the garden, then consider the following tips for growing and maintaining the canna.
The cannas, which grow up to 1.5 meters high, love a full-sun, absolutely wind-protected location. There you can plant the flowers from mid / late May. Please note, however, that you have to keep a sufficient distance from other plants when planting, because a canna plant grows to between 60 and 100 centimeters wide.
You can also plant cannas in large containers. However, these should absolutely have a water drain. The cannas usually grow just as well in tubs. Another advantage of container storage is that you only have to store your cannas in winter, i.e. digging is not necessary. (Link tip: Wintering of tub plants - tips and hints)
As soon as the easy-care cannas bloom in the garden beds in late spring, they also ignite a real fireworks display there. And if you pluck the withered petals again and again immediately, new flowers will quickly form on the stick again and into autumn.
»Fertilization / watering:
The heavily draining cannas need regular fertilizers throughout the season. It is best to use a complete fertilizer here. You should also keep the roots of the flowers moderately moist. So you have to water the plants regularly, but you should avoid waterlogging.
At the end of October, you should cut back your cannas to a height of about 5 centimeters so that they can then spend the winter without any problems.
As soon as you put the cannas back in the garden next spring, you can multiply them by dividing the rhizomes (breaking).
Cannas cannot withstand our freezing temperatures, which is why you must overwinter the flowers in cool, frost-free and completely dark rooms (if necessary, wrap them in an opaque jute sack).
For the wintering of the canna, you should put the rhizome in a pot of potting soil and keep it as dry as possible - however, it must not dry out completely, which is why you should moisten it with a water sprayer from time to time.
If you plant the rhizome properly back in a pot from January onwards and prefer it, you can put it outdoors much more easily in May. For this purpose, you should put the canna rhizome in lukewarm water for 24 hours before putting it in fresh soil.
