1. Monitoring function

Canna can remove and monitor the damage caused by harmful gases such as sulfur dioxide and chlorine, and issue warnings. When it is found that its leaves turn green and turn white, flowers and fruits fall off, we should pay special attention to chlorine pollution.

2. Maintenance guidelines

The main results are as follows: (1) sufficient light is required in the light growth period, and it is guaranteed to receive at least 5 hours of direct sunlight every day. The environment is too dark and lack of light, which will delay the flowering period.

(2) temperature Canna prefers a higher temperature, and the optimum temperature for growth is 15-28 ℃. If the temperature is below 10 ℃, it is disadvantageous to its growth.

(3) watering canna can endure stagnant water for a short time, but it is afraid that too much water will easily lead to root rot. Canna should be watered frequently when it is just planted, once a day, but the amount of water should not be too much. During drought, more water should be sprayed on branches and leaves to increase humidity.

(4) sufficient base fertilizer should be applied in the soil before fertilization and planting, and fertilizer should be applied frequently during the growing period. When the plant has 3-4 leaves, liquid fertilizer should be applied every 10 days until it blossoms.

(5) Canna canna can be propagated by sowing method or plant division method.

(6) cut off the unfinished flowers as soon as possible after pruning and blooming, so as to reduce the cost of nutrition and promote the plants to continue to sprout new flower branches; after Frosts Descent in the north, if the canna is exposed to frost, the exposed parts of the canna will all wither and yellow. at this time, the withered and yellow part of the ground should be cut off, dug out the rhizome, slightly dried and buried in the house with sand, and then replanted the following spring.

(7) Canna can be planted directly in the courtyard, or planted in wooden buckets or large flowerpots and placed in living rooms, balconies, rooftops, corridors, etc. [Jishan Huayao]
