Light: Canna is suitable for full sun, so it should be placed in a place with sufficient light. Temperature: The suitable growth temperature is 15 to 30°C. Watering: Determine the frequency of watering according to soil conditions. During the growth period, spray water on the leaves every day to moisturize. Soil: Choose fertile, loose, sandy soil. In addition, pay attention to the amount of fertilizer when fertilizing, and pay attention to timely pruning after flowering.

1. Breeding methods

Light

Canna is suitable for full sun growth. If the environment is too dark and the light is insufficient, the flowering period will be delayed. If you place it in a cool place when it is blooming, you can extend the flowering period.

Temperature

The suitable growth temperature of canna is 15℃-30℃. When blooming, placing canna in a place with low temperature and no light can extend the flowering period. The ambient temperature should not be lower than 10℃.

When the temperature reaches above 40℃, the canna can be moved to a ventilated and cool place. Before and after frost, potted cannas can be moved to a temperature of 5-10°C to survive the winter safely.

Watering

During the growth period, cannas need to spray water on the leaves 1-2 times a day to maintain humidity.

Since canna loves fertilizer and tolerates moisture, the pot must be watered thoroughly, and the frequency of watering should be determined according to the actual situation.

Fertilization

Apply sufficient base fertilizer before planting. In addition, top-dressing fertilizer is required 3-4 times a month during the vigorous growth period.

Soil

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

2. Precautions

Guarantee Light

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

Pay attention to controlling the amount of fertilization

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

If you apply too much fertilizer during the summer heat, it will burn the canna's rhizomes and cause them to "burn to death."

Stop fertilizing the canna during its flowering period and winter.

Do not water too cool in summer

In hot summer, water that is too cool can cause leaf edges to scorch.

Prune in time after the flowers lag behind

When the flowers at the stem end lag behind, the stems and branches should be cut off from the base at any time to allow new buds to germinate and flower branches to bloom one after another.
