A Detailed Guide to the Latest Cultivation Methods for the Golden Doll Daylily

The Golden Doll daylily is a horticultural cultivar of the daylily (Hemerocallis) produced by artificial cultivation, also known as the yellow lily. It originated in North America and was introduced to Beijing by the Chinese Academy of Sciences last century. It is distributed in Jiangsu, Henan, Shandong, Zhejiang, Hebei, Beijing and other places, and its cultivation and management are simple, making it suitable for clump planting as accents in urban parks, plazas and other green spaces. Now let us take a look at the cultivation methods for the Golden Doll daylily!

Propagation Methods

The Golden Doll daylily can be propagated by tissue culture and division. The annual propagation coefficient is generally 1:6, and can reach 1:10 in fertile soil. Division can be carried out during the dormant period. In spring, from February to March, dig up plants that are more than 2 years old, divide them so that each bud becomes one plant, and each plant must have a complete bud head. Then plant them at a row spacing of 40 cm and a plant spacing of 25 cm, with planting holes 10-12 cm deep. First apply base fertilizer into the hole, cover with a little fine soil, then plant, cover with 4-5 cm of soil after planting, firm it down, and then water thoroughly. Division can also be done in March. In the Jiangsu-Zhejiang area, before early February, cut apart dense clumps, keeping two or three buds per clump, and replant; they can bloom the same year.

Soil Selection

The Golden Doll daylily likes warmth and ample sunlight, is cold-hardy, and requires deep, fertile soil. For pot cultivation, the soil should be loose and well-drained, and fertilizer should be applied regularly during the growing season. In the north, the underground tubers need to be dug up before frost and stored in an environment at about 5°C. Because its flowers are large and brightly colored, rich in color, with a good plant form, it is easy to cultivate. The optimum temperature for open-field cultivation is 13-17°C. It is not strict about soil and grows best in loose, fertile, well-drained sandy loam, and it also adapts to fertile clay soil. In the Jiangnan region, it can overwinter outdoors in a wind-sheltered spot.

Planting Spacing

The Golden Doll daylily is a dwarf variety and also a perennial flower with a relatively high propagation coefficient. Sparse planting gives a poor ornamental effect, while dense planting affects ventilation and tillering. Generally, a plant spacing and row spacing of 20×20 cm or 15×25 cm is suitable. Divide and replant once every one or two years. The cultivation soil should be moist, fertile, well-drained sandy loam. After planting, spray with new high-fat film, which can effectively prevent aboveground water from evaporating, prevent water in the seedlings from transpiring, isolate pests and diseases, and shorten the seedling recovery period.

Fertilizer and Water Management

The Golden Doll daylily has a long flowering period. Spraying with flower-strengthening agent can promote strong buds, large petals, bright flower color, and a longer flowering period. Its green period is also long. In terms of fertilizer and water management, it requires sufficient base fertilizer, and after the peak flowering period, organic fertilizer and compound fertilizer should be applied as a top dressing. During the cultivation period, loosen the soil and weed 1-2 times in spring and summer. From March to June, apply diluted decomposed human manure urine at 3-5 times water each month. If phosphorus fertilizer is applied once before flowering, it can improve flower quality. Daylilies like moisture, so water them in a timely manner, and spray with new high-fat film to retain fertilizer and moisture.

Disease Control

For the prevention of rust, leaf spot and leaf blight in the Golden Doll daylily, on the basis of strengthening cultivation management, weeds, old leaves and dried flower scapes should be cleaned up in a timely manner. At the early stage of disease, for rust, spray 15% triadimefon 1-2 times for control; for leaf blight and leaf spot, spray 50% mancozeb or similar for control.
