Canna, also called Indian flower cane, impresses with its exotic and colorful flowers. In this article you will learn why flowering can fail, what helps in this case and how to properly care for cannas to get beautiful flowers.
Why doesn't the canna bloom?
If the canna does not bloom, the cause is often anutrient deficiency. Either there was not enough fertilizer or the water was watered with too much lime. Lime hinders nutrient absorption. This weakens the plant and cannot adequately supply the flower.
What can you do to make the canna bloom again?
If your canna is not blooming or blooming only sparsely, you should first find out the cause. If there is a nutrient deficiency, with appropriate fertilization andgood care you can possibly expect new flowers this season. The flowering period of the canna extends from June to August. With the right care, the flowering period can be extended into September.
How to care for canna for magnificent flowers?
In order to have enough strength for beautiful flowers, cannas should be cared for as follows:
- The canna should be in a warm, protected location. If it is too shady or too windy, the flowers will not bloom.
- Fertilize regularly, especially in the growth phase before and during flowering.
- If possible, water with rainwater or lime-free water to avoid chlorosis (deficiency condition).
- Canna is a swamp plant and needs to be kept moist. The earth must never dry out.
- Canna is sensitive to frost and must be overwintered frost-free.
Why doesn't the canna bloom despite good care?
You have cared for your canna well, fertilized it sufficiently and watered it properly, and yet no flowers are forming? Thenisit's probablydue to age Young, annual plants are not yet flowering. They are still developing their flowers and then bloom for the first time in the second year. Even old plants lack the strength to form new flowers. They must be rejuvenated and multiplied by division.
How can you particularly promote the flowering of the canna?
- For early flowering, place the rhizomes in the ground after overwintering in January or February and place them in a warm location.
- Remove spent flowers regularly during the flowering period. This stimulates the formation of new flowers.
- Always ensure proper and regular nutrient intake. Fertilizer can intensify the flower color.
Tip
Pot size can also affect flowering
Another reason why Canna produces few or no flowers can be the size of the pot for potted plants. If the pot is too small, the plant has no space, the roots are squeezed and cannot absorb enough nutrients. If the pot is too big, the plant will put all its energy into rooting and will not be able to develop flowers.
