Vervain can be reproduced by sowing, or by dividing, and the survival rate is relatively high. Sowing propagation can be carried out in the spring period, select the vervain robust seeds, sow them in loose and breathable soil, half a month or so can be sprouted. Propagation by division can be carried out before the verbena buds, cutting the underground fast roots of the verbena and planting them in potting soil.
How to propagate serpentine
Serpentine can be propagated by sowing, which is suitable for spring or fall period, with high success. Select robust seeds and sow them in loose, fertile and more permeable nutrient soil or sandy loam. After sowing, you need to water moderately, and during the maintenance period you need to control the water, keep the soil moist and stabilize the temperature between 18 and 22 degrees.
Under the condition of sufficient light and water and suitable temperature, Verbena can usually germinate in about 12 to 15 days. After the vervain germinates and emerges, it needs to strengthen the management, and during the maintenance period, it needs to be given enough light, water and fertilizer. Sowed verbena, can be transplanted during the spring period, and can bloom in about 2 years.
Vervain has a developed rhizome and can also be propagated by dividing the plants, which can be done in spring before sprouting. Choose a disease-free mother plant, remove it from the potting soil, mainly do not hurt the root system. Cutting the strong underground tuberous roots of the mother plant, can be transplanted into loose and fertile potting soil, moderate watering, soaking the soil, is conducive to the adaptation of the tuberous roots to the new soil.
After transplanting, you need to put the verbena in a cool and ventilated location. During the maintenance period, you need to give the verbena appropriate amount of water, to keep the soil moist. Later, after the verbena is planted, according to its growth habit, reasonable maintenance. During the maintenance period, you need to moderate watering and fertilization, to provide it with sufficient nutrition.
