When raising at home, you can buy the cultivated soil directly in the horticultural shop. When we get home, we add a small amount of ceramsite or dry bark to the nutrient soil we buy. Ceramsite: dry bark = 2:1. But the soil planted with Anthurium andraeanum should keep good permeability and drainage.
Before planting, the soil must be disinfected. However, if you are preparing special soil, this step can be omitted. The purpose of disinfection is to make red palm have less chance of suffering from diseases and insect pests in the later period of growth.
The most suitable growth temperature of Anthurium andraeanum is 14 ~ 35 ℃. In winter, the temperature is lower than 10 ℃, red palm is easy to be frostbitten, and the temperature is increased in time. In summer, when the temperature is higher than 35 ℃, spray water around red palm to cool down.
Hongzhang likes fertilizer. It needs more magnesium. It's better to go to a professional florist to buy foliar fertilizer with higher magnesium content. Or choose water-soluble compound fertilizer diluted into liquid fertilizer to fertilize Anthurium andraeanum. Spray once a week during growth. When applying fertilizer, adhere to the principle of "applying thin fertilizer frequently". It is better to use less than more, but it will burn seedlings directly.
The watering of Anthurium andraeanum needs to be carried out according to the drying degree of the basin soil. According to the rules summarized by Huayou, we need to do it once every three days in spring and autumn. Two days in summer, and in summer, spray at the noon to spray on the leaves to increase humidity. In winter, water once every 5-7 days.
When it's cold, water between 9:00 and 16:00 in the morning. When watering, pay attention to alternate dry and wet to avoid watering in case of serious water shortage, which will affect the growth and development of Anthurium andraeanum.
High temperature and humidity are the environment that red palm likes. Humidity is related to temperature, room temperature is higher than 28 ℃, we need to manually increase indoor humidity. The humidifier or sprinkling can be used for humidification. When the temperature is lower than 20 ℃, the indoor humidity can be maintained without watering.
In winter, even if the indoor temperature is high, it is better not to over cool and moisturize. If the leaves are too wet at night, they will reduce their ability to resist the cold, make them frostbite, which is not conducive to winter.
Red spider, nematode, cabbage worm, whitefly, thrips, snail and scale insect are the most common pests in red palm, especially spider, nematode and cabbage worm. However, Anthurium andraeanum is very sensitive to insecticides. If only insecticides can be used, it is better to choose low concentration ones. It should be noted that all pesticides containing copper, such as dimethoate, dichlorvos, malathion, parathion, methamidophos, etc., will cause toxicity to Anthurium andraeanum. It is better not to use them.
In order to avoid excessive consumption of Anthurium andraeanum, we should cut off the dead branches and branches in time during the growth of Anthurium andraeanum, and the cutting technology of Anthurium andraeanum has the theory of "three adjustments and two cuts", that is, adjust the direction, adjust the plants, cut the buds, cut the flower buds and cut the old flowers.
