The cold-sensitivity of a Canna is no reason to leave the tropical beauty of the blossom after a single season to their fate. In fact, all the beautiful varieties of a Canna indica have the floral persistence of a perennial. It is therefore worthwhile to take a closer look at the right measures for hibernation. This guide sets out the best strategy for hibernating Indian flowerpipe. Learn everything here for the perfect preparation, the ideal winter quarters and a professional care.
Why does not the Canna tolerate frost?For generations, the wonderful Canna is a familiar image when planted out or spreading in the pot with its lavish summer blooms in parks and ornamental gardens, colorful South Seas flair. This is hardly surprising, since Indian flowerpots have been cultivated in Europe since the 16th century. Notwithstanding this long history in our regions, the magnificent flower beauty has nothing to oppose winter conditions. Home to Canna in South America, especially Brazil, Argentina and Colombia, where annual average temperatures rarely drop below 20 degrees Celsius.
Why is wintering still worthwhile?Their tropical origin does not mean that Indian flowerpipe is limited to a one-year guest performance in the garden. In their habitats, the plant thrives as a herbaceous perennial, which is wild in the wild. Following its heyday, the pseudo-stem with the leaves retracts into its powerful, up to 60 cm long rhizomes. With the onset of the next growing season, the Canna drives out of their persistence organs to re-stage their flower festival. At the right location and cared for properly, the Blumenrohrgewächs can be very old. This habit makes a hibernation worthwhile.
preparatory workIt's not enough just to give a canna in the pot before winter. So that the tropical plant survives the cold season, it depends on a targeted preparation. This includes that you can enjoy the splendid flowering period until October in peace and quiet. Then give the Indian flower tube enough time to transfer the remaining nutrients from the pseudo-stem and the leaves into the rhizomes. This process is recognizable by completely withered flowers as well as brown-orange discolored leaves and stems. How to properly prepare a Canna indica for wintering:
- At the beginning of November cut the shoots to 5 to 10 cm
- Carefully lift the rhizome out of the ground using a digger fork or small shovel
- Remove adhering soil with a paintbrush or rinse with water
- Cut off damaged, rotten root pieces with a sharp, disinfected knife
- Remove dried, dead hair roots as well
Tip: The risk of rot and mildew in winter quarters is reduced if you sprinkle the rhizomes with a quinosol solution and allow to dry long before adding them. The agent is available in tablet form in the pharmacy. Dissolve 1 liter of Chinosol per liter of lime-free water and pour the mixture into a hand sprayer.
Instructions for hibernation in the potThe prepared Canna rhizomes set aside for a few days in a shady, airy place to dry. Well suited is a grid as a base, so that the roots can dry from all sides. The earth sprouts spend the winter dry, cool and frost-free. That is how it goes:
- The rhizomes hit in several layers of newspaper (no glossy paper)
- Alternatively put in a pot with dry sand, sawdust or straw
- Spend in a dark room with temperatures around 10 degrees Celsius
So that an Indian flower tube does not prematurely expel in winter quarters, the thermometer must not exceed the 15-degree mark. If the room in the basement is in the immediate vicinity of the heating system, heat could be a problem, even though it is dark and air-dry here. Better suited is a dark, frost-free attic or unlit storeroom.
Transition from winter to springFlowering rhizomes offer the option of a premature flowering period by driving the plant forward. For this purpose, a Canna is awakened from hibernation in the course of March. This process is similar to the advancement of tuber begonias or dahlias. How to proceed:
- Get rhizomes out of winter quarters
- Remove any adhering earth with a brush
- Put a mix of 4 parts sand and 1 part leaf compost into a pot
- Insert the rhizomes so deeply that they are just covered with substrate
- Set up in a bright, warm location
- First, pour only a little until the first shoots show up
- Water more proportionally to growth and fertilize every 14 days
Tip: The more powerful a rhizome, the more vigorously it survives overwintering. A decisive factor in its vitality is the quality of the tub substrate during the summer growth and flowering period. A nutrient-rich compost-based soil is well-suited, ideally enriched with well rotted horse dung.
Overwintering in the bed - That's how it worksIn regions within the Z8 winter hardiness zone, a Canna planted in the bed may overwinter. The herbaceous parts of the plant already die off at temperatures below 10 degrees Celsius. The strong rhizomes survive deep in the ground after all still cold to - 10 degrees Celsius. On the Lower Rhine, in mild river valleys or wine-growing areas, you can thus save yourself the opportunity to get into a winter quarter. Instead, escort Indian flowering tub in the bed with the following precautions through the winter:
- At the beginning of November, cut the plant down to a few feet above the ground
- Spread a 15 to 20 cm thick layer of mulch on the root disk
- Suitable materials are foliage, brushwood, fir fronds or straw
- Unsuitable materials are stones or gravel
