How to propagate Verbena by cuttings

Cutting time

Cuttings are generally taken from April to July, with temperatures around 15-20 degrees Celsius.

Cutting medium

The cutting medium must be water-retaining and permeable. It is difficult for ordinary families to get the ideal cutting medium. Here we can buy ready-made cutting medium. Medium-coarse river sand can also be used, but it needs to be rinsed with clean water several times before use, and it is best to disinfect it. Do not use river sand from saline-alkali areas as it is not suitable for the growth of flowers and plants.

Selection of cuttings

Cuttings are usually carried out in combination with pinching, and the thick, pest-free, and strong growing tops are selected as cuttings.

Management after cutting

temperature

The rooting temperature of Verbena is 18-25 degrees Celsius. When the temperature is below 18 degrees Celsius, the plant will take root slowly. When the temperature is above 25 degrees Celsius, the cut ends of the cuttings are easily infected and rotted by pathogens, and the higher the temperature, the greater the rot. If the temperature is low during cuttings, you can use a film to cover the flower pot or container for cuttings. When the temperature is too high, provide shade. Place the cuttings in a cool place and mist them frequently.

humidity

After cuttings, the air humidity must be maintained at a high level, and the relative humidity should generally be maintained at 75-80%. The cuttings can be sprayed every day, 1-3 times a day. The number of sprays should be increased when the temperature is high on sunny days, and less or no spraying should be done on cloudy and rainy days. Be careful not to over-spray, as the cuttings can easily be infected by bacteria in the water and rot.

illumination

Cutting propagation cannot be separated from sunlight. However, the stronger the light, the higher the temperature inside the cuttings, the more vigorous the transpiration of the cuttings, the more water is consumed, which is not conducive to the survival of the cuttings. Therefore, after cuttings, 50-80% of the sunlight must be blocked. After the roots grow out, the shading net can be gradually removed: on sunny days, remove the shading net at 4:00 p.m. every day, and cover it before 9:00 am the next day.
