It really looks like a tall, outstanding beauty standing there, delicate and charming. How should you grow such a beautiful flowering plant? Let's learn together.

Cultivation methods and precautions for Canna indica 'Purpurea'

1. Light

During its growing period, it requires full sun, meaning the light must be sufficient, and it should receive at least five hours of sunlight every day. The environment must not be too dark, otherwise the light will be insufficient, which will then affect its flowering time. In addition, if you place it in a relatively cool spot while it is blooming, you can effectively make its flowering period longer.

2. Temperature

This plant is relatively suited to 15-28°C. When it blooms, in order to make the flowers last longer, you can place it in a spot with a lower temperature and no light, and the temperature in the environment must not be lower than 10°C. When the temperature reaches 40°C, you can move it to a relatively cool and ventilated place. Around the time of Frost's Descent, you should also move it to a place with a temperature of 5 to 10°C, so that it can safely overwinter.

3. Fertilizing

Although sufficient base fertilizer has already been applied before planting, during its vigorous growth period it also needs 3 to 4 rounds of topdressing. If it still has not bloomed and produced flower buds 20 to 30 days before flowering, then a little fertilizer should also be applied at this time. Sometimes its leaf edges will turn dry and yellow, which may be caused by strong light exposure or being too dry. In the relatively hot summer, if the water is too cold it can also make it turn yellow, and applying fertilizer that is too concentrated will even burn its roots directly, so fertilizing is something you must pay attention to, and it must not be too much or too concentrated.
