The culture method of drunken butterfly flower

Drunken butterfly flower, also known as butterfly grass, purple dragon beard, spider flower, etc., is a 2012 herb of cauliflower family, native to tropical America, with light and elegant petals, flying like butterflies when in full bloom, quite interesting. You can arrange flower beds and flower borders in summer and autumn, or you can dwarf them as potted plants. Let's take a look at the breeding methods of drunken butterflies.

The growth habit of drunken butterfly flower

Drunken butterfly flowers are native to tropical America and are cultivated in tropical to temperate zones around the world for ornamental purposes. Strong adaptability, sexual like high temperature, more resistant to summer heat, avoid cold. Like plenty of sunshine, semi-shaded land can also grow well. Fertile soil with sufficient water and fertilizer, tall plants and generally medium fertility soil can also grow well, while sandy loam or clayey soil or alkaline soil can grow poorly. Like moist soil, but also more resistant to drought, avoid stagnant water.

The breeding method of drunken butterfly flower

1. Sowing: the drunken butterfly flower sowed its seeds in the open field seedbed in the middle of April, and the seedlings emerged neatly. The seedlings grow slowly, need time after sowing, transplant when they have 2-3 true leaves, plant or pot in June, fertilize once a half month during the growing period, if fertilized too much, it is easy to grow plants and affect plant shape and flowering, generally spring sowers blossom in autumn, autumn sowers watch flowers indoors in winter and spring.

2. Cutting: the substrate of drunken butterfly cuttings is nutritious soil or river sand, peat soil, etc., the optimum temperature for cuttings to take root is 18 ℃, below 18 ℃, the relative humidity of the air must be kept at 75% 85%, the humidity can be increased by spraying the cuttings, at the same time, the sun must be covered by 50% 80%, and then the shading net is gradually removed after the root system grows.

The culture method of drunken butterfly flower

1. Soil: drunken butterfly flowers do not need special soil, preferably sandy soil containing humus with good drainage. Except for poor growth in alkaline soil, it can grow in sandy soil and clayey soil, and grow best in slightly acidic sandy loam. Rotten leaf soil and vegetable garden soil can be used to cultivate soil.

2. On the pot: when installing the pot, the drunken butterfly flower should first put a coarse-grained matrix or ceramsite 2 cm thick at the bottom of the basin, sprinkle it with a fully mature organic fertilizer as base fertilizer, with a thickness of about 1-2 cm, then cover it with a layer of substrate about 1-2 cm thick, and then put in the plant to separate the fertilizer from the root system and avoid root burning.

3. Fertilization: like other grass flowers, drunken butterfly flower requires more fertilizer and water, but it is required to follow the principle of "light fertilizer applied frequently, less and more times, complete nutrition", and keep leaves and flowers dry at night after fertilization. Potted pregnant buds need to be applied 2 or 3 times with thin compound liquid fertilizer, which can blossom during the Spring Festival.

4. Heart-picking: the drunken butterfly generally carries out two heart-picking before flowering, in order to promote the germination of more flowering branches, remove the top tip one to two weeks after the pot, retain the lower 3-4 leaves, promote the branches, carry out the second heart-picking 3-5 weeks after the first heart-picking, and remove the residual flowers in time when planting the flower bed.

5. Watering: drunken butterfly flowers are more resistant to drought, but grow better when given greater air humidity, and should be watered thoroughly in midsummer. Like higher air humidity, air humidity is too low, will accelerate the withering of a single flower. Also afraid of rain, need to keep the leaves dry at night. The optimum relative humidity of the air is 65-75%.

6, lighting: drunken butterflies like high temperature and heat resistance, the most suitable growth temperature is 20 ℃ to 32 ℃, like the sun is warm, resistant to heat, slightly resistant to semi-shade, not cold-resistant, the plant dies in case of frost, although it can grow under semi-overcast conditions, but in order to dwarf it, it is better to see more direct light as much as possible, preferably more than 4 hours a day.

7. Diseases and insect pests: drunken butterfly flowers are often harmed by leaf spot and rust. Leaf spot disease is sprayed with 50% tromethamine wettable powder, and rust can be sprayed with 3000 times of 50% verapamil wettable powder. Lepidoptera pests are easy to occur in the seedling stage, so the insecticide avermectin 4000 times can be sprayed on the leaves.
