How to Propagate Daylilies? A Detailed Guide to the Latest 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 formerly a commonly used dye material, 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 collected around September each year. Then they are sown in the spring of the following year. Before sowing, the seedbed must first be prepared, with the land deeply plowed and raked, and the area of the seedbed properly controlled. Drainage ditches should be dug, then sowing furrows should be dug with the sowing density properly controlled, and the seeds should be placed evenly into the sowing furrows. After sowing, cover with fine soil and water thoroughly. Before the seedlings emerge, water appropriately and do a good job of weeding to keep the soil moist. They can be transplanted at around the autumn of the same year.
2. Division Propagation
Division propagation is usually carried out in spring each year. First, pull up the old daylily plants with their roots, then separate the old dead roots from the fibrous roots. When dividing, make sure each clump carries buds, control the row spacing for planting, and plant about 5 plants per planting hole. When planting, pay attention to the planting depth; it must not be too deep. After planting, water thoroughly to settle the roots, provide shade, and keep the soil moist. Then apply appropriate topdressing according to growth conditions and do a good job of cultivating and weeding. In addition, when the seasons change in autumn and winter each year, pay attention to hilling the soil, combining it with cultivation and weeding. Then divide the plants again about every 4 years to ensure vigorous growth of the daylilies.
3. Cutting Propagation
Cutting propagation of daylily is generally carried out in spring and autumn each year. Adventitious buds on the old daylily plants are cut off to serve as cuttings. Then disinfect and sprout the cuttings, prepare the cutting medium, and insert the cuttings vertically into the medium. Water appropriately to keep the soil moist and improve the soil's moisture retention capacity. When the cuttings root, apply an appropriate amount of slow-release fertilizer. Then increase the duration and intensity of light, and transplant when the root balls of the cuttings are full. Each year after the cuttings finish flowering, an appropriate amount of phosphorus and potassium fertilizer can be applied to promote root growth and increase the flowering rate the following year.
4. Bud Division Propagation
Bud division propagation mainly involves cutting the small plantlets off the daylily flower stems. If the plantlets are too large, a second cut should be made before planting the divisions. Then, as with cuttings, prepare the medium, disinfect the divisions, and transplant them appropriately. Under normal management, roots can form about 7 days after transplanting. After rooting, strengthen management according to the methods for managing seedlings to improve the survival rate. The bud division propagation method can increase planting yield and expand one's own planting benefits.
The above is a brief introduction to daylily propagation methods. In fact, there is also a tissue culture method, which mainly uses daylily organs such as tender leaves and flower scapes to culture into plants. However, it is rather troublesome to carry out, so few people use this method when propagating. That is all for today's introduction. This article is for reference only.
