Drunken butterfly flower belongs to the plant with good conservation, and does not need special soil. It is better to have sandy soil with humus and good drainage. The root system of Pieris is relatively developed, and the basin should be a little deeper, with a basin diameter of 20 cm to 30 cm as the best.
Except for poor growth in alkaline soil, it can grow in sandy soil and clayey soil, and it grows best in slightly acidic sandy loam. It can be used as culture soil by mixing rotten leaf soil and vegetable garden soil. Loose soil and good drainage are required.
I like warm sunshine, heat resistance, half shade resistance and cold resistance. Summer is the growth period, the plants will die in case of frost. The suitable temperature is 20-32 ℃.
Watering: it can withstand drought, but it will grow better if it is given higher air humidity. Water every day in midsummer, and water thoroughly. Like higher air humidity, air humidity is too low, will accelerate single flower withering. Also afraid of rain, need to keep the leaves dry at night. The optimum relative humidity is 65-75%.
Fertilization: like other grass flowers, the drunkard butterfly flower requires more fertilizer and water, but it is required to follow the fertilization (water) principle of "frequent application of light fertilizer, less time and more nutrition", and keep the leaves and flowers dry at night after fertilization. As a pot load, it needs to apply 2-3 times of thin compound liquid fertilizer in the pregnancy stage, and it can bloom during the Spring Festival.
When the seedlings are loaded into the basin, first place a 2-2cm thick coarse-grained substrate or ceramsite at the bottom of the basin as the filtering layer, sprinkle a layer of fully decomposed organic fertilizer as the base fertilizer, with a thickness of about 1-2cm, then cover a layer of substrate, with a thickness of about 1-2cm, and then put the plants to separate the fertilizer and the root system, so as to avoid burning the root.
After the basin is poured, it will be watered once, and placed in a slightly shaded environment for maintenance for a week.
Generally, two times of coring should be carried out before flowering to promote germination of more flowering branches: after one to two weeks of potting, or when the seedling height is 6-10 cm and there are more than six leaves, the top tip should be removed and the lower 3-4 leaves should be reserved to promote branching.
After the first 3-5 weeks, or when the length of the lateral branch reaches 6-8 cm, the second time is to remove the top of the lateral branch and retain 4 leaves under the lateral branch. After two heartbeats, the plant type will be more ideal, and the number of flowers will be more. When planting flower beds, the remaining flowers should be removed in time so that they do not bear fruit to extend the flowering period.
In addition, it should be noted that Lepidoptera insects are easy to appear in the flowering stage of Pieris, and the insecticide abamectin 4000 times can be used for foliar spraying.
