A Detailed Guide to Daylily Planting Time and Cultivation Techniques

AbstractPlanting time: plant in spring and autumn, or transplant in early autumn and after frost in winter. Planting method: dense planting of daylilies can give play to the advantages of the colony, increasing the number of tillers, bolting and flower buds, so as to achieve the purpose of increasing yield. Proper deep planting helps the plants survive and grow vigorously. After planting, water should be poured to settle the roots. Before the autumn shoots emerge, keep the soil moist. During the growth period, according to growth and soil compaction, carry out 3-4 times of intertillage, and combine deep plowing of the soil with additional winter fertilizer. Usually actively prevent and control diseases and insect pests.

Planting crops requires following the growth patterns of the crop. If planted too early, the climate conditions are unsuitable and the seed germination rate will be relatively low; if planted too late, the best time for growth is missed, affecting the yield of daylilies. Therefore, everyone must do the right thing at the right time.

Daylily Planting Time

1. It is best to plant daylilies in spring and autumn. Keep the temperature inside the shed at 25 degrees during the day and not lower than 12-15 degrees at night. Seedlings can emerge in 1 week. After emergence, gradually lower the shed temperature to adapt to the outside climate and prevent the seedlings from growing leggy.

2. There are two most suitable seasons for transplanting daylilies: one is the early autumn period, that is, the period after the flower buds are picked and before the autumn shoots sprout; the other period is the winter dormancy period after frost in winter, from the withering of the autumn shoots to before the sprouting of the spring shoots the following year.

Daylily Cultivation Techniques

1. Reasonable dense planting: dense planting of daylilies can give play to the advantages of the colony, increasing the number of tillers, bolting and flower buds, so as to achieve the purpose of increasing yield. Generally, wide and narrow row cultivation is mostly used, with wide rows 60-75 cm, narrow rows 30-45 cm, and hole spacing 9-15 cm. Plant 2-3 plants per hole, with 45,000-75,000 plants per hectare, reaching 1.5 million-2.25 million plants per hectare in the full production period.

2. Proper deep planting: the root group of daylilies grows from around the shortened stem, and has the characteristic of 1 layer per year, with the rooting position moving upward year by year from bottom to top. Therefore, proper deep planting helps the plants survive and grow vigorously. The suitable planting depth is 10-15 cm. After planting, water should be poured to settle the roots. Before the autumn shoots emerge, the soil should often be kept moist to facilitate the growth of new shoots.

3. Intertillage and earthing up: daylilies have fleshy roots and need fertile and loose soil environmental conditions to facilitate the growth and development of the root group. During the growth period, according to growth and soil compaction, carry out 3-4 times of intertillage. The 1st time is carried out when the seedlings are just emerging, and the 2nd-4th times are carried out during the bolting period together with intertillage for earthing up.

Daylily Propagation Methods

1. Division: division propagation of daylilies is the most commonly used propagation method. One way is to dig out the entire mother plant clump and replant it after division; another way is to dig out part of the plants from one side of the mother plant clump as seedlings, and let the remaining ones continue to grow. However, when digging and dividing seedlings, try to damage the roots as little as possible.

2. Cuttage: after daylily harvest is completed, select from the middle and upper parts of the flower scape those with fresh green bracts and obvious growth points below the bracts, cut them off leaving about 15 cm above and below the growth point, and insert them flat into the soil in a slight arc. After about 1 week, they can grow roots and sprout.

3. Sowing: daylilies can produce seeds through artificial pollination. When sowing, use fertile garden soil as the seedbed. Soak the seeds in warm water at 25 degrees C for 48 hours. After sowing, cover with 2 cm of soil. Usually seedlings can emerge in 1 week. After emergence, gradually lower the shed temperature to adapt to the outside climate.

Four Essential Matters for Daylilies

1. Clear ditches and drain waterlogging: daylilies are relatively delicate and fear both flooding and drought. Therefore, before overwintering, ditches should be opened deep so that the ditches are connected and water dries after rain stops.

2. Earthing up to protect the crowns: in winter, after the aboveground parts of the daylily plants wither, earthing up should be carried out to protect the crowns. First cut off the withered plants level with the ground, properly spread miscellaneous fertilizer, pond sludge fertilizer, etc. on the root clumps, and then earth up with 10 cm of fine soil.

3. Prevent and control insect pests: remove all weeds and residual leaves around the vegetable plot, spray comprehensively once with 0.5 degree Baume lime-sulfur mixture, then spread 30-50 kg of quicklime per mu and spray 600---800 of the new high-fat film solution, so as to kill overwintering insect eggs and bacteria while also preserving heat and preventing freezing and preventing soil compaction,

4. Apply more winter fertilizer: combine with deep plowing of the soil, apply 1000-1500 kg of decomposed pig and cattle manure per mu, or 2500-3000 kg of soil miscellaneous fertilizer, plus 30-35 kg of superphosphate.

The planting of daylilies not only requires respecting the growth patterns of daylilies and planting at the appropriate time, but the cultivation techniques of daylilies are also very important. The editor reminds everyone here that planting is a cause that requires careful management, so do not wait until the daylily is cold to regret it.
