Which month is the best to plant daylily?

When planting daylily , it must go through a certain period of low temperature before it can bolt and bud, otherwise it cannot switch from vegetative growth to reproductive growth. The fleshy roots can be divided into spindle roots and cylindrical roots. Daylily has strong adaptability to soil and is a light-loving crop. So, generally speaking, which month is the best to plant daylily?

Which month is the best to plant daylily?

The best time to plant daylilies is in spring and fall. Spring planting usually takes place between March and May, when the temperature is suitable and rainfall is sufficient, which is conducive to the growth and development of daylily seedlings. Autumn planting takes place from late September to mid-October.

Key points for planting daylily

1. Site selection

Daylily prefers a mild climate and has strong adaptability, but its above-ground parts are not frost-resistant and easily wither. It has a strong root system and excellent drought resistance, and is suitable for growing in hillside areas. It has a wide range of adaptability to soil and can grow in a variety of soil types, including sandy soil, clay, plains and mountainous areas, especially red and yellow soil is the most suitable.

2. Land preparation

As a perennial plant, daylily needs deep tillage when the land is cultivated to promote good development of the root system. The depth of tillage should be 20-30 cm, after which the land needs to be leveled, ridges built and drainage ditches constructed to form suitable ridges. In order to facilitate later management, the bed width is recommended to be kept between 1-1.5 meters, and the length should be determined according to actual conditions, with ease of operation as the criterion.

3. Reproduction method

Daylily can be propagated in a variety of ways, including seed propagation, division, cutting, budding and tissue culture. Seed propagation is a quick way to obtain seedlings, but because the germination rate is not high, the seeds need to be soaked and germinated in advance, and it takes a year after sowing before they can be transplanted.

4. Growth cycle

The growth cycle of daylily is divided into seven stages: February to early to mid-March is the budding stage, mid-March to late May is the leaf unfolding stage, late May to mid-June is the bolting stage, mid-June to early July is the bud formation and flowering stage, early July to early August is the leaf withering stage after picking, early August to before the first frost in autumn is the autumn leaf unfolding stage, and after the frost to January of the following year is the dormant period.

5. Transplantation and planting density

The transplanting of daylily can be carried out after the flower buds are harvested and before the new seedlings sprout in spring. It is best to divide and transplant immediately after harvesting, so that winter seedlings can grow in the same year, new roots can be developed, and nutrients can be accumulated, laying the foundation for bolting and yield in the following year. In fertile rice fields or vegetable garden soil, 16,000 holes can be planted per acre; while in sloping land or poor soil, 2,000 holes can be planted per acre. It is ideal to use alternating wide and narrow rows when planting. After transplanting, water should be poured immediately to help the plants take root, and the roots should be covered with wood ash. After the plants have taken root, 100 to 200 kg of human feces and urine mixed with water can be used per acre as root fertilizer.

In summary, if you want to grow daylily, you can choose to do it during these two time periods. In addition, field management is also very important.
