Canna cultivation methods and precautions

1. Breeding methods

illumination

Canna is best grown in full sunlight. If the environment is too dark and there is insufficient light, the flowering period will be delayed. If you place it in a cool place while it's blooming, you can extend its flowering period.

temperature

The suitable growth temperature of canna is 15℃-30℃. When it blooms, placing canna in a low temperature and light-free place can prolong the flowering period. The ambient temperature cannot be lower than 10℃.

When the temperature is above 40℃, canna can be moved to a ventilated and cool place. Before and after the Frost Descent, the potted cannas can be moved to a place with a temperature of 5-10℃ so that they can safely overwinter.

Watering

During the growing season, canna needs to be sprayed with water 1-2 times a day to maintain humidity.

Since cannas like fertilizer and are tolerant to moisture, the pot must be watered thoroughly and the frequency of watering should be controlled according to the actual situation.

Fertilization

Apply sufficient base fertilizer before planting. In addition, top dressing should be done 3-4 times a month during the peak growth period.

soil

Canna does not have high requirements for soil, but it grows best in loose, fertile, well-drained sandy loam, and fertile clay soil is also acceptable.

2. Precautions

Ensure lighting

Canna requires sufficient light during the growing period, ensuring that it receives at least 5 hours of direct sunlight every day.

Pay attention to controlling the amount of fertilizer

Potted cannas sometimes have scorched and yellowed leaf edges, mainly due to excessive application of ferrous sulfate.

If too much fertilizer is applied during the hottest summer months, it will burn the rhizomes of the canna and "burn them to death."

Stop fertilizing cannas during their flowering period and over the winter.

Avoid excessive cooling when watering in summer

In the hot summer, if the water temperature is too cold, it will cause the leaf edges to burn.

Prune after the flowers have fallen

When the flowers at the end of the stem fall, the stem should be cut off from the base at any time to allow new buds to sprout and flower branches to grow and bloom.
