For the breeding methods and matters needing attention of asparagus iron, fertilization should be light, avoid concentration, and loosen the soil and turn the basin regularly.

Soil: asparagus iron needs loose and fertile soil. Moisture: water is watered every 4 days in spring and autumn and every day in summer. Lighting: like direct sunlight, but need proper shade in summer. Temperature: the suitable growth temperature is 20-28 ℃, and the overwintering temperature is not less than 8 ℃. Fertilization: apply fertilizer solution once every half a month or so, do not use thick fertilizer and raw fertilizer. Diseases and insect pests: actively control leaf spot disease, anthrax and so on. Note: loosen the soil every month and turn the basin in April every year.

Asparagus iron plant shape short and strong, its stem straight, dragon beard iron young trees are generally only about 90cm, its leaves are sword-shaped, dense growth at the end of the branches, young trees, the color is bright green, and when shaping, the color will become bright red or purple, bronze, milky white, pink, looks colorful, very beautiful.

1. Soil

Asparagus iron has high requirements for soil. It is necessary to cultivate soil with loose and fertile soil, good drainage and air permeability, and high content of organic matter. Generally, garden soil, rotten leaf soil, rotten organic fertilizer and river sand are mixed according to the ratio of 5-5-3-1-1-1. If there is no soil cultivation method, the substrate can be fully mixed with perlite, vermiculite and peat soil.

2. Moisture

Asparagus iron likes the warm and humid environment, and the growing soil should also maintain a certain degree of wettability, which can be irrigated from the top of the plant, which can keep the soil moist and increase the wetness in the air, creating a suitable growth environment for asparagus iron. It is irrigated every 4 days or so in spring and autumn, while it is watered every 1-2 days in summer, and the leaves can be sprayed many times.

Third, lighting

Longxu iron can withstand shade and likes warm sunlight. It can be placed on the windowsill where the sun is not very strong, so that it can fully absorb sunlight, and the leaves will not be sunburned and eventually yellowed because of strong light. It is most appropriate to shade properly in summer, and the illumination is 40% Rue 50%.

4. Temperature

The most suitable temperature for the growth of asparagus iron is 20 ℃-28 ℃, if the temperature is higher than 32 ℃ in summer. When the winter temperature is lower than 15 ℃, the asparagus iron will go into dormancy or semi-dormancy, so it should be properly shaded in summer and moved to indoor breeding when the temperature is low in winter, but it should be noted that the indoor temperature should not be lower than 8 ℃.

5. Fertilizer management

In order to grow better, asparagus iron should be sprayed with a small amount of fertilizer during the growing period, usually once in half a month, and can not be fertilized with thick fertilizer and raw fertilizer, which will lead to the phenomenon of thick and burning roots.

VI. Diseases and insect pests

Leaf spot disease and anthracnose will occur in Longxu iron seedling stage, which will directly lead to withered leaves, and the growth of Longxu iron seedlings will also be affected. It can be sprayed with 70% mancozeb wettable powder or 50% methyl topiramate 600-800 times, once every 7-10 days, 3-4 times continuously, which can be effectively prevented.

Asparagus iron leaves fade, wither, or even fall off, serious will lead to plant death, at this time should be red spiders in the juice, you can use 20% trichloropropanol emulsion to add 8-1000 times water spray or dichlorvos emulsion with 1000-1500 times water spray, once a week, continuous spraying 3-4 times, can effectively kill and control the production of red spiders.

VII. matters needing attention

To make the asparagus iron grow better, it is necessary to loosen the soil once a month, so that its roots can always be in a good permeable state. If stagnant water is found in the basin, it should be sent out immediately, and the pot should be turned to change the soil after the pot soil is dry. Because asparagus iron is used as a small plant for family potted plants, it is necessary to turn the pot every year when it is put outside in early April, which can meet the needs of dragon beard iron for soil fertility in this year.

Potted asparagus iron can not make it grow very tall, so when sprouting new shoots in spring, you should control watering, as long as you keep the pot soil moist.
