Why don't canna blossom?

Canna prefers a warm and humid growing environment, and as long as water and fertilizer are supplied in time, it will not only grow luxuriantly and blossom, but also greatly improve its ornamental ability as a potted plant. The flowers of canna are not only rich in colors and bright colors, but also very large and charming.

There are many people who like canna in daily life, and canna is widely used, not only as a garden green plant, but also as a potted plant. Whether it is used for landscaping or family potted plants, it often has a very high ornamental value and is deeply loved by people. But if the canna does not blossom, will its charm still exist?

We can imagine that the huge branches and leaves of canna with huge flowers can be called exquisite. If only the leaves grow but do not blossom, no matter how luxuriantly the branches and leaves grow and do not blossom for a long time, they will be overshadowed as a garden application or as a family potted plant, and the ornamental effect will be greatly reduced. So why don't canna blossom?

In fact, canna does not blossom, usually due to improper maintenance and management. According to the habit characteristics that canna likes warm and humid growing environment, and likes light and water and fertilizer, we can carry out investigation from these aspects. Because only when these conditions are met will the canna trees bloom.

First, lack of light

Canna is a kind of light-loving plant, its huge leaves will not only evaporate a large amount of water, but also has a prominent advantage, that is, it receives a large area of light. The large leaf area can ensure that the plant can better promote photosynthesis, so as to ensure that it can maintain good growth. However, if the canna is placed in a more shady environment for a long time, because it does not get effective photosynthesis in time, then it is easy to grow branches and leaves without flowering. Therefore, we need to provide it with sufficient light in time, and usually the more light, the higher the quality of flowering.

Second, the temperature is too low

Canna has the characteristics of heat resistance but not cold resistance, usually the higher the temperature, the more it likes, and the more brilliant it blossoms. The original canna florescence is very long, generally from March to December, especially in winter in December, if the temperature is too low, it may not blossom. Therefore, in order to ensure that it can blossom smoothly, it can be placed in the bright sunny place near the window, and the temperature should be adjusted to suit its appearance and bloom.

Third, improper watering

Canna prefers wet growing environment, so it is necessary to do a good job in watering management in time to avoid water shortage, because the drought tolerance of canna is relatively poor. If the lack of water is serious, the plant will lack the water needed for flowering, so it is difficult to blossom. Even if it blossoms, it is small in quantity and low in quality. Therefore, when planting canna, since it has the characteristic of being wet, we should do a good job in water management in time. Of course, if the plant is in a state of stagnant water for a long time due to overwatering, it is easy to have rotten roots, not to mention not to blossom, not to die.

IV. Improper fertilization

Canna not only likes to be wet, but also likes to be fat, especially at the flowering stage. However, it is not allowed to apply fertilizer at flowering stage, and it can be fertilized properly before and after flowering, especially through reasonable topdressing before flowering, plants can store a lot of nutrients, which lays a solid foundation for flowering. And after flowering, the residual flowers need to be cut off in time and fertilized reasonably again, so as to ensure that they bloom again after 1-2 months. However, if the plant lacks nutrients and fails to top fertilize in time, it will be difficult for the plant to blossom under the condition of insufficient nutrients. Of course, if excessive fertilization, it will also cause fertilizer damage and rotten roots, which can also cause poor growth of the plant, even if it does not die, the branches and leaves may wilt and not blossom. Therefore, fertilization must be scientific and reasonable.
