Cultivation Methods and Techniques for White Daylily
Today's topic is the cultivation methods and techniques for white daylilies and the precautions for maintaining them in green plant flower planting. The editor of this site will introduce the following content to everyone.
Also known as Yu Chun Bang, Bai He Hua, and Bai Yu Zan, the daylily is a common ground cover plant in parks and courtyards, and it is also cultivated in pots. Daylilies prefer shady and moist environments and are afraid of strong sunlight, growing well in fertile, well-draining soil. It is a perennial herbaceous plant of the genus Hemerocallis in the Liliaceae family, and China is one of its native habitats. Below is an introduction to the cultivation methods and precautions for daylilies.
I. Cultivation Methods
1. Light
Daylilies enjoy shade and are not tolerant of strong sunlight. It is best to place them in a shady window sill or in a room without direct sunlight when grown at home. Shading is a must during the summer.
2. Temperature
Daylilies can withstand severe cold, with the optimal growth temperature being 15 to 25°C. When the temperature drops below 0°C in winter, the above-ground parts will wither, but the underground rhizomes can survive, sprouting again when the climate is suitable the following year. Therefore, there is no need to keep them in a warm place during the winter; a temperature above 5°C is sufficient.
3. Watering
Daylilies enjoy moisture and require frequent watering, but the amount of water should not be excessive, and there should be no standing water. Special care should be taken to avoid rain to prevent the potting soil from becoming overly wet and causing root rot. Watering can be done once in the morning and once at night during the summer, while less watering or暂停 watering is needed during rainy days or low temperatures.
4. Soil
Daylilies prefer loose, breathable, and rich humus content sandy soil. A mixture of peat soil and perlite can be used, with the addition of ceramsite. The clay content in the soil should be low, and it should not be too poor.
5. Fertilizing
Seedlings can be fertilized every 15 days, and during the flowering period, fertilizing should be done every 7 days. Organic fertilizer can be used, and fertilization can be adjusted according to the growth condition of the daylily flowers.
6. Disease and Pest Control
Common diseases and pests of daylilies include spot disease and white绢 disease, which should be controlled in a timely manner. For example, a diluted Benomyl solution can be sprayed to control spot disease once every 7 days, repeated three times.
7. Potting and Soil Replacement
Usually, the pot needs to be changed once a year. New buds will sprout on the blocky roots of the daylily every year. It can be divided once every 2 or 3 years, and potting can be combined with the need for division.
8. Pruning
Usually, withered leaves should be cut off to increase ventilation and light transmission. Especially during and after flowering, withered flowers and leaves should be pruned in a timely manner.
9. Propagation Methods
Propagation of daylilies commonly uses the division method, and seeding can also be used. The division method is often used for plants that have been planted for more than a year and is best done in early spring.
The method of division involves digging up the mother plant, removing the soil around the roots, and exposing it to the sun for 1 to 2 days before cutting the rhizome with a sharp knife. Each new plant can have one or several buds. After planting the new plants, water them once to settle the roots, and then keep the soil slightly moist.
II. Precautions
The management of daylilies should be based on the season and growth condition. For instance, in January, prevent low temperatures from injuring the rhizome, in March, loosen the soil and fertilize, avoid sun exposure when temperatures rise, pay attention to drainage during the rainy season, apply phosphorus fertilizer during flowering, prune after flowering, and in winter, prune the withered parts above ground and cover with fine soil for cold protection.
