How to Propagate Daylilies? A Detailed Guide to Common Propagation Methods
Daylily is a traditional Chinese medicinal herb and ornamental flower in China. Daylily has various effects such as clearing heat and promoting diuresis, and treating edema. It is mainly used to treat difficult urination, blood in the urine and stool, and its medicinal value is relatively high. It was also a commonly used dye material in the past, and its ornamental value is not low either. Nowadays, more and more people are growing daylilies, so how should they be propagated when growing them? Below, the editor brings you the propagation methods for daylilies. Let's take a look!
1. Seed propagation
Seed propagation is the most common propagation method in daylily cultivation. Seeds are usually harvested around September each year. Then they are sown in the spring of the following year. Before sowing, first prepare the seedbed, carry out land preparation and deep plowing, and control the area of the seedbed well. Dig drainage ditches, then control the sowing density and dig sowing furrows, and place the seeds evenly into the sowing furrows. After sowing, cover with fine soil and water thoroughly. Before emergence, water appropriately and do a good job of weeding to keep the soil moist. Transplanting can be done around the autumn of that year.
2. Division propagation
Division propagation is usually carried out every spring. First, pull up the old daylily plants with their roots, then separate the old dead roots from the fibrous roots. When dividing, pay attention that each clump has buds, control the row spacing for planting, and plant about 5 plants per planting hole. When planting, pay attention to the planting depth, which should not be too deep. After planting, water thoroughly to settle the roots, do a good job of shading, and keep the soil moist. Then apply additional fertilizer appropriately according to the growth situation, and do a good job of cultivating and weeding. Also, when the seasons change in autumn and winter each year, pay attention to earthing up, together with cultivating and weeding. Then divide the plants again about every 4 years to ensure vigorous growth of the daylilies.
3. Cutting propagation
Cutting propagation of daylilies is generally carried out in spring and autumn each year. Cut off the adventitious buds on the old daylily plants to serve as cuttings. Then disinfect and promote sprouting of the cuttings, prepare the cutting substrate, and insert the cuttings vertically into the substrate. Water appropriately, keep the soil moist, improve the soil's moisture retention capacity, and apply slow-release fertilizer appropriately when the cuttings are rooting. Then increase the light duration and intensity. After the root balls of the cuttings are full, transplant them. Each year after the cuttings finish flowering, apply phosphorus and potassium fertilizer appropriately to promote root growth and increase the flowering rate the following year.
4. Bud division propagation
Bud division propagation mainly involves cutting off the small plantlets on the daylily flower stems. If the plantlets are too large, then a second cut should be made before planting the divided buds. Then, as with cutting propagation, prepare the substrate, disinfect the divided buds, and transplant them appropriately. Under normal management, they can take root about 7 days after transplanting. After rooting, strengthen management according to the methods for managing seedlings to increase the survival rate. The method of bud division propagation can increase planting yield and expand one's planting benefits.
The above is a brief introduction to daylily propagation methods. In fact, there is also the method of tissue culture, which mainly uses organs of the daylily such as tender leaves and flower stalks to culture into plants. However, it is rather troublesome to operate, so few people use this method when propagating. That is all for today's introduction. This article is for reference only.
