Generally speaking, if the temperature is too low or the sun is not enough, red palms are not easy to bloom, or even if they are not bright. Other factors, such as too little water and lack of fertilizer, will also lead to less flowering of Anthurium andraeanum. Therefore, in order to have a good look, we must do the following
Red palm likes sunshine, but it is not suitable for direct sunlight, because the leaves will be burned. Therefore, it is best to put red palm in the bright astigmatism link to avoid the sun exposure and not too cool. With sufficient scattering of sunlight, flowers will bloom more.
Red palm likes to be wet. When the basin soil surface is dry, it can be watered once every 2-3 days. Red palm also has certain requirements for air humidity. At ordinary times, it should also pay attention to spray water around the leaves. This ensures that the flowers are bright and full. If the temperature is low, the growth of Anthurium andraeanum is slow, then we should control watering to avoid rotten roots.
Anthurium andraeanum is more fond of fertilizer. It can be fertilized once every two weeks at the same time as watering, and P and K fertilizer can be applied before flowering. The best time to apply fertilizer is
Morning or evening. Fertilize once a month in winter.
In addition, red palm also need to apply some water and fertilizer. When watering, drop one or two drops in, once every 3-5 days, once every half a month in winter
Don't use foliar fertilizer on red palm, because it has a layer of wax on its surface, which will hinder absorption.
The soil of Anthurium andraeanum is better to be acid, fertile and well drained. You can spread some coarse sand, ceramsite or peanut shell on the bottom of the basin. In addition, soil hardening will hinder root respiration and nutrient delivery, but also affect the quality of flowering, usually pay attention to loose soil, when necessary, timely change basin.
Some roots of Anthurium andraeanum will be exposed to the soil surface. Many flower friends are afraid of bad flowers, so they should bury them. Do not do this, these exposed roots are called air roots, to better absorb nutrients and breath, burying is equivalent to hindering his breath, will also lead to poor bloom.
There are many factors that cause the yellow leaves of Anthurium andraeanum, such as light, temperature, ventilation, watering, fertilization and so on. So encounter yellow leaf symptom, we must distinguish carefully, suit to the case.
Sometimes, the edge of the leaves of Anthurium andraeanum will be dry and yellow, with burning marks. The cause of this situation is not necessarily the sun exposure, but also the possible long-term uneven light, even in the astigmatic environment, the long-term side of the light will be burned
Therefore, keep the red palm in the room, always rotate the flowerpot, on the one hand to avoid one side of the burn, on the other hand to ensure the beautiful plant type.
Red palms like a mild environment. If the whole leaves of red palms are dark yellow and lusterless, they will fall off seriously, which is caused by too high or too low temperature.
When the temperature is higher than 35 ℃ in summer or lower than 10 ℃ in winter, red palm should be kept indoors. Maintain its stable growth environment.
Waterlogging and rotten roots will cause the leaves to turn yellow or even black, and the plants will be depressed.
We should stop watering, move the red palm to a ventilated place, loosen the soil, and wait for the water in the basin to evaporate. After the red palm recovers its vitality, it can be maintained normally. If the situation is serious, then we need to repair the roots and change the pots.
When the indoor ventilation is not good, there will be yellow brown spots on the leaves of Anthurium.
In this case, the yellow leaves need to be cut off in time, or other healthy leaves will be infected and turn yellow. Then we need to strengthen ventilation. Usually pay attention to open more windows to ensure the exchange of air with the outside world.
If the leaves of Anthurium andraeanum start to turn yellow from the edge, they are accompanied with yellow spots and easy to fall off. This is due to the lack of phosphorus and nitrogen. You can apply some crushed eggshells and ripe rice washing water
In fact, many diseases are caused by improper water and fertilizer and inadequate ventilation. Generally, as long as we maintain them properly, we can avoid diseases and insect pests. But if it happens, how can we save it?
There are two most common diseases of Anthurium andraeanum: leaf spot and anthrax. It can be sprayed with chlorothalonil solution or soaked in a basin, which can be eliminated quickly.
If it is nematode, scale insect, can use spectrum insecticide or pyrethroid spray kill, very effective.
If it's a spider, you can spray some god of flowers or mites.
If the situation is not serious, you can spray washing powder water directly.
