Methods and Precautions for Growing Canna
Do you know about these? The content regarding the methods and precautions for growing canna and the tips for maintaining healthy canna plants in the field of green plants and flowers is explained in detail by the editor below.
Timely Indoor Transition: The minimum temperature for overwintering should not be lower than 5°C. In the north, it should be moved indoors before winter, with the room temperature preferably above 10°C.
Reduce Watering: Watering should be controlled, and water can be added only when the potting soil is completely dry. Excessive watering in winter not only causes root rot but also increases the chance of frostbite.
Stop Fertilizing: In winter, the plant's demand for nutrients decreases, so fertilizing should be paused. Fertilizing can be resumed when the temperature rises in spring.
Light Conditions: Ensure adequate light every day. It can be placed on the balcony for cultivation. Insufficient light can cause yellowing of the leaves.
One, Timely Indoor Transition
Canna is a tropical plant with poor cold tolerance. The minimum temperature for overwintering should not be lower than 5°C. If it's an area in the south where the temperature does not drop below 5°C in winter, it can be left outdoors. If it's a cold region in the north with low temperatures, it should be moved indoors before the temperature drops in winter and keep the indoor temperature above 10°C to ensure it can survive the winter.
Two, Reduce Watering
In the low-temperature environment of winter, the growth of canna slows down, and its demand for water decreases significantly. Therefore, the amount of watering should be reduced. Water should be added only when the potting soil is completely dry to ensure normal growth of the plant without water deficiency. If excessive watering occurs, the low temperature in winter cannot evaporate the water in time, and the plant cannot absorb it quickly, leading to waterlogging and root rot.
Three, Stop Fertilizing
In winter, the plant's vital activities decrease, and its demand for nutrients also decreases significantly. Therefore, fertilizing is not needed in winter, and it can be resumed in April when the weather warms up in spring. Excessive fertilizing in winter can easily cause fertilizer damage, and in severe cases, even death.
Four, Light Conditions
Whether it is outdoor cultivation or indoor overwintering, it is necessary to ensure adequate light. During indoor overwintering, it can be placed on the windowsill to receive a longer duration of light every day, helping the plant maintain a green and vigorous state. If there is a long-term lack of light, the leaves tend to turn yellow, which is not good for the plant's growth next year.
