Propagation methods of canna

Canna is a perennial perennial herb, native to tropical America, India, Malay Peninsula and other tropical regions. It has large and colorful flowers, rich colors, good plant shape, easy cultivation, and has the function of purifying the air and protecting the environment. It is an ideal flower for greening, beautifying and purifying the environment. It is usually propagated by sowing and dividing roots. Let's take a look at the breeding methods of canna.

Sowing and reproduction

Before sowing, the canna seeds should file a hard seed coat, then soak it in 25 ℃ water for 24 hours, and then sow it in plain sandy soil. The covering of the soil should not be too thick, and it should be 1-2 times the seed diameter. After sowing, keep the soil moist at a temperature of about 20 ℃. After a week, it can germinate, and when the seedling height is 5 cm, it can be planted separately.

Rhizome propagation

The rhizome of canna usually propagates at the beginning of March every year. The rhizome stored in the previous year is cut into pieces, the rotten part is removed, each piece has two or three bud holes, and then it is planted directly in a flowerpot or buried in plain sand. Pay attention to keep the soil moist and keep the temperature between 10 and 15 degrees. About 20 days, when the bud is 4-5 cm long, it can be divided into pots.

Ramet propagation

Canna plantlets are usually propagated on cloudy and rainy days from June to July or in the evening. If the distance between plants or clumps is more than 4-5 cm, cut down vertically from plants with sharp tools, split plants or clumps quickly, pay attention to more soil, do not damage branches and leaves, and then plant directly into the planting hole, water thoroughly in time after planting, and properly shade the sun to increase humidity if the environment is relatively dry. After about 10 days of maintenance, the new plant can not develop into a complete plant.
