Soil selection

Be sure to disinfect the soil before planting, but if you are suddenly preparing professional soil bought from a professional store, you can skip this step, so that Anthurium andraeanum is less likely to suffer from diseases and insect pests in the later stage of growth.

Temperature requirement

The most suitable growth temperature of Anthurium andraeanum is 14-35 ℃. When the winter temperature is lower than 10 ℃, Anthurium andraeanum is prone to frostbite and increase in time. When the summer temperature is higher than 35 ℃, sprinkle water around Anthurium andraeanum to cool down. The temperature is high in summer, pay attention to ventilation and sprinkling water, and cultivate in greenhouse in winter.

Illumination factor

Anthurium likes sunlight, vegetative growth stage, increase light, promote growth; during flowering, reduce light to prevent bud discoloration and affect ornamental. It is difficult to blossom if there is not enough sunlight during the growing period, but Anthurium andraeanum is not suitable for direct sunlight and will burn leaves. The best way is to put Anthurium andraeanum in a cool place and be exposed to astigmatism, so as not to be too cool. It is protected from the burning of strong light and refracted sunlight for photosynthesis.

Notes on fertilization

Anthurium likes fertilizer, the demand for magnesium fertilizer is higher, it is best to go to a professional florist to buy foliar fertilizer with high magnesium content. Or choose water-soluble compound fertilizer diluted into liquid fertilizer to fertilize Anthurium andraeanum. Anthurium andraeanum generally uses root topdressing and liquid fertilizer every seven days or so. Adhere to the principle of "applying thin fertilizer frequently" when fertilizing, it is better to have less than more, and the more will burn the seedlings directly.

If the room temperature is higher than 28 ℃, we need to increase the indoor humidity manually. Humidifier or sprinkler can be used to humidify. When the temperature is lower than 20 ℃, the indoor environment humidity can be maintained without watering. In winter, even if the indoor temperature is high, it is best not to cool and moisturize too much. Excessive humidity of plant leaves at night will reduce its ability to protect against cold and make it frostbite, which is not conducive to winter.

Soil discomfort

The soil and water in most northern areas contain more salt and alkali, lack of soluble iron needed for plant growth, and do not change soil for a long time, resulting in the lack of nutrients in the plant, the leaves will gradually lose green and turn yellow.

You can buy professional acidic soil from the florist, or treat the original soil. Oxalic acid is added to the soil to change its acidity and basicity. You can also pour some acidic water every week, dilute it with lemonade or edible vinegar and then pour it.

Air drying

The growth of Anthurium andraeanum needs high air humidity, but when the indoor air is too dry in winter, the leaf tip is dry and yellowing, or the leaf edge is scorched, or the leaf is scorched, the edge is curled and so on.

According to the growth characteristics of Anthurium andraeanum, properly increase the air humidity and often spray to the leaves and the surrounding environment. Keep the plant away from the air outlet of heating and air conditioning as far as possible in winter.

During the flowering period, the plant should be maintained in a place with sufficient light and no direct sunlight, which can appropriately increase the light intensity.

The temperature is not suitable

If the indoor temperature is too low in winter, the leaves will turn yellow; if the room temperature is too high, the plant transpiration is too high, and the root water and nutrients are insufficient, the leaves will turn yellow. In winter, people usually move the plants indoors near the doors and windows. Between the doors, the leaves turn yellow when they are hot and cold. Therefore, the indoor temperature should be relatively stable.

Too much watering

The new leaves of Anthurium andraeanum are yellow and the old leaves are normal, which is generally caused by too much water, which makes the soil in the basin too wet for a long time, or even stagnant water, causing part of the fibrous roots to rot, hindering normal breathing and absorbing nutrients, causing the leaves to turn yellow and fall off gradually.

The stagnant water in the basin should be discharged in time. If the plant is in an environment where the soil is too wet for a long time, the plant can be removed from the basin and the soil can be dried and replanted. After normal watering, the leaves will gradually return to green.

Uneven fertilization

Little fertilization, or no change of soil for a long time, lack of nitrogen and other nutrients in the soil led to thin branches and leaves, thin and yellow leaves. In addition, excessive fertilization will also appear new leaves hypertrophy, uneven, while old leaves dry tip, scorched yellow shedding.

If fertilizing too little, trace mineral elements should be added, and fully water-soluble fertilizers such as "Huaduoduo" can be used. " If the leaves turn yellow due to excessive fertilization, you should stop applying fertilizer immediately and increase watering. In serious cases, part of the old soil can be removed, replaced with new soil, and managed normally after replanting.
