Anthurium, also known as fire crane flower and safflower candle, is a perennial evergreen herb of the monocotyledonous plant genus Anthurium. Its leaves are emerald and green, and the large red Buddha flame bud petals are wrapped in golden yellow columnar stamens, and the surface also has a layer of waxy luster, which is of high ornamental value and is deeply loved by people.
Anthurium flowers are dormant in low temperatures in winter, and after the temperature rises in spring, Anthurium flowers also usher in a period of vigorous growth. Spring anthurium flowers have "3 fears", if you do not pay attention to maintenance, the leaves will change from green to yellow, flowers from red to black, and anthurium to "black palm".
1. Fear of watering too much
Anthurium flowers are tropical rainforest plants that prefer moist environments. Watering the anthurium flower properly has many benefits for its growth, and the plant will grow watery. If the soil is too dry, it can seriously interfere with growth. However, everything must have a degree, although anthurium likes to be moist, but if you water too often, allowing the soil to accumulate excessive water, it will also cause root rot. After the roots rot, the ability to absorb water and nutrients decreases, the leaves will turn yellow and wither, the red petals will gradually turn black and wither, and even the entire plant will die in severe cases.
Usually, you can't lack water and you can't water too often. Observe the surface of the soil before watering, and only after seeing that the surface of the soil is white and dry, then water it. If the soil surface is not dry, there is no need for watering. When watering, slow down and slowly water the whole soil with a small stream of water.
2. Afraid of thick fat and burning roots
After the temperature rises in spring, the anthurium ushered in a rapid growth period, with many new shoots popping up at the bottom and gradually growing into branches and buds. Anthurium flowers are dormant in winter and are generally not fertilized throughout the winter. There is no fertility in the original soil to meet the needs of spring growth, so when the spring temperature stabilizes above 15 degrees, we need to regularly fertilize anthurium flowers to supplement nutrition.
The root system of anthurium flower is aerial root, which is more sensitive to fertilizer, and must not apply too much at one time when fertilizing. If the fertilizer concentration is too high, it will cause fertilizer damage to the root system of anthurium, and the leaves and flowers will wither or even die in large quantities. Fertilizing anthurium flowers in spring, whether solid fertilizer or liquid nutrient solution, should be used according to the lowest concentration in the proportion of the instructions. In early spring, the weather has not yet warmed up, anthurium flowers grow slowly, do not rush to fertilize at this time, otherwise the plant can not absorb fertilizer, easy to cause fertilizer damage.
3. Fear of soil alkalinization
Anthurium is a tropical rainforest plant that prefers loose, fertile, well-drained and humus-rich slightly acidic soils. Only if the soil is good enough can the root system of Anthurium flowers grow vigorously in spring. Most florists will use tap water to water their flowers, and the disinfectants and other substances contained in tap water make the tap water alkaline. Long-term use of tap water to water anthurium, the soil will slowly change from slightly acidic to alkaline, and the originally loose structure will become hard and compact. The root system of anthurium cannot grow normally in such soil, and over time, the problems of yellowing of leaves and stagnation of growth will occur.
Under normal circumstances, it is necessary to change the soil of anthurium flowers every 1~2 years. Spring and autumn, the temperature is neither cold nor hot, and it is best to change the soil. Novice florists recommend buying ready-made nutrient soil directly, old florists can match soil according to their own conditions, and share a soil matching method here: use 3 parts of peat soil, 2 parts of perlite, a little organic fertilizer or slow-release fertilizer as the bottom fertilizer, all the above materials can be used as nutrient soil after mixing well.
If you don't want to change the soil for the time being, you can also prepare some ferrous sulfate agents. According to the ratio of 1:1000, mix the agent into clean water, stir well to make the liquid liquid. Watering the roots of anthurium flowers with ferrous sulfate solution, watering 1~2 times in January, can also play a role in preventing soil alkalizing.
