Cultivation method of white crane taro (matters needing attention in raising white crane taro)

White palm, also known as white crane taro, is commonly known as "smooth sailing", and its flower language is: beautiful, noble, virtuous, friendly and confident. The flower of white palm is graceful and flawless, and is regarded as "innocent flower", so people will think that white crane taro has auspicious meaning, and because of its vigorous growth and shade tolerance, it is favored by people, and potted plants are often seen indoors.

Knowledge points of daily maintenance of white palm:

Point 1, lighting

Astigmatism is best to raise white palm, and the indoor lighting conditions of general families are especially suitable for raising white palm. Specific breakdown: winter and early spring need better light, do not shade; At the end of spring, the temperature is getting higher and the light is getting stronger. It is necessary to gradually shade the sun until the end of autumn, when the temperature drops. If you keep it in the shade all the time, don't suddenly expose yourself to the sun, otherwise you won't wither, yellow leaves or even die because of sudden changes in the environment and sensitivity to strong light.

Second, the temperature.

Anthurium andraeanum was originally a plant growing in subtropical and warm zones, and it likes warmth all year round. The optimum temperature is 15~30℃. When the temperature is below 5℃, pay attention to cold and warmth, otherwise the leaves will be frozen; When the temperature is higher than 35℃, the leaves are easy to dry up and have no spirit.

Third, humidity.

White palm needs high air humidity. If the air is too dry, the leaves will turn yellow and dark. Specifically, it can be solved by spraying water on leaves or on the ground; It can be covered with transparent plastic bags, but in the case of high temperature and good light, it is necessary to ventilate slightly or open a hole in the upper end of the plastic bag for ventilation, otherwise the temperature in the bag will rise sharply, resulting in the leaves of Anthurium andraeanum being cooked.

Fourth, fertilization.

White palm likes thin fertilizer, and it is forbidden to apply thick fertilizer or raw fertilizer. Generally, a little base fertilizer is applied when changing pots, or a little thin water fertilizer is applied in spring and autumn. It is best to use compound fertilizer as the main fertilizer instead of single nitrogen fertilizer, otherwise it will not bloom easily.

Fifth, common pests

The common pest is red spider, the technical term is "mite damage", which is characterized by wilting, dull and yellow leaves. It can be controlled by spraying acaricides such as dicofol, nisolone and pyridaben.

Sixth, common diseases.

Common diseases are bacterial leaf spot and root rot. For leaf spot disease, carbendazim wettable powder can be sprayed 500 times. For root rot, in addition to paying attention to ventilation and reducing watering and humidity, 800 times of chlorothalonil wettable powder can be sprayed on the leaves and poured into pots to achieve the purpose of prevention and control.

Reasons why Anthurium does not bloom:

Insufficient light is the main factor that affects Anthurium andraeanum not to bloom. Generally, Anthurium andraeanum is kept indoors in potted plants, and insufficient light is an easily overlooked problem. If this is the reason why it doesn't bloom, then the solution is simple, that is, move it to a sunny place, for example, gradually move it to the edge of the window sill.

▲ White palm lacking light

If you want to blossom, you need induction. In addition to insufficient light, if Anthurium andraeanum still does not bloom, it also needs some induction. The specific method is to spray gibberellic acid, which will bloom in a month or two. It should be noted that the concentration of gibberellic acid should not be too high, but should be 1000- 1500 times that of water. If the concentration is too high, the flowers will be deformed.

Why are flowers sometimes green?

Traditionally, the flowers of Anthurium andraeanum are white, and the flowers of Anthurium andraeanum are red, and the flowers of Pink Palm are pink. So why are the flowers of Anthurium sometimes green?

There are two main reasons: 1 it is normal that the color of flowers will gradually darken in the later stage and finally turn green like leaves; The second is the influence of light. If the maintenance environment is not well lit, the color of the white palm will be darker. If you move to a well-lit place, the color will gradually turn white.

How to solve the problem of white palm and yellow leaves

When Anthurium palmatum does not bloom, it is mainly to appreciate its leaves, which are green and wide, with lines on them, and have certain ornamental value, but if the leaves turn yellow, it will affect its ornamental value. The yellowing of Anthurium andraeanum leaves mainly depends on three main factors: light, humidity and adequate nutrition.

1. Influence of light: According to the season, if it is a yellow leaf in summer, it must be too light and need to be moved to a cool place. If it is winter, it is likely that the light is too weak and needs to be gradually moved to a warm and sunny place.

2. Effect of humidity: White palm likes humidity. If the air is too dry, it will not only turn yellow, but also look gray and dull. At this time, we can use a watering can to fill the leaves of white palm or the surrounding air with water, and spray it several times a day.

3. Insufficient nutrition: Anthurium palmatum needs to be changed once a year, and water and fertilizer should be supplemented during the peak growth period and flowering period.
