Key points for cultivation of daylilies

Water and fertilizer

The water and fertilizer management of daylilies is very simple. Due to the long flowering period, in addition to applying sufficient base fertilizer at the end of the flowering period, top dressing is required two or three times during the flowering period. Mainly supplement with phosphorus and potassium fertilizers, and you can also spray 0.2% potassium dihydrogen phosphate to promote flower enlargement and extend the flowering period. At the same time, combine watering to promote more branches and early budding. Such lack of fertilizer and water will lead to a high bud drop rate and affect the amount of flowering.

Tillering

Daylilies have a strong tillering ability, so the plant spacing must be maintained at 30 cm * 40 cm when planting. After planting, inter-cultivation and weeding should be carried out in time during the seedling stage. During the seedling stage, tillage should be shallow rather than deep, and the tillage should become deeper as the age increases. The soil should be loosened shallowly before the spring seedlings emerge, and then shallowly weeded 3 or 4 times after emergence, which can achieve the dual purpose of weeding and drought prevention. Intertillage weeding should be done when the soil is moderate and can be stopped when the leaves cover the land. Remove weeds in the daylily field in time. If weeds are overgrown, they are likely to cause corresponding diseases and pests, which will affect the growth and appearance of daylilies. After flowering, cut the flower stems from the ground and remove the dead leaves at the base of the plants in time.

Root system

The biological characteristics of the root-shaped daylily are that it starts from the root system, grows roots from bottom to top, one layer per year, and moves upwards year by year. When daylilies enter the peak flowering period, the root system grows very well. Before the seedlings emerge, add soil to the top of the scattered beads cluster and cultivate it around the plants. Thickening the soil layer can improve the soil quality. Before the spring buds sprout, the soil from the top of the loose bead cluster is cultivated around the plants. Please note that this is only suitable for daylilies that have entered the peak flowering period. Young plants should not be cultivated.
