[what to do if the leaves of white palm turn yellow] how to raise white palm well

Friends who cultivate white palms should know that if the newly bought white palms appear improper nursing or other reasons, the leaves of white palms will begin to turn yellow gradually. What is the reason for the yellowing and shedding of the leaves of white palm?

The reason for the yellowing and shedding of white palm leaves:

The yellowing of white palm leaves is mostly due to stagnant water, of course, fat yellow and other reasons are not ruled out, but according to the case analysis of many flower friends, the yellowing of white palm leaves is caused by stagnant water and poor ventilation. The leaves of white palm are yellowed for the following common reasons.

1. Soon after I bought it, the leaves of the white palm turned yellow.

This reason is generally caused by plants not adapting to the new environment. Some flower friends immediately asked how to make white palm adapt to the environment. First of all, don't start watering, fertilizing, changing soil, and changing pots when you buy it. Think that such plants will lead a good life, but in fact, newly bought plants, according to their habits, try not to change soil and change pots, after a few days, wait for plants to grow normally, and then consider changing pots and so on.

Said so much did not talk about the reasons for the yellowing of white palm leaves, newly bought, change pots or soil, the root system can not recover, resulting in the leaves yellowing.

2. After raising it for some time, the leaves of white palm began to turn yellow.

This situation depends on watering. Some flower friends water once every three days and only remember the number of days without looking at the potted soil, which eventually leads to long-term wetness of the potted soil, which can easily lead to stagnant water and yellowing of leaves. Could it be fat yellow? if the breeding time is not very long, it will not, unless it has been raised for a long time, the normal growth is the yellowing of leaves, which may be caused by lack of fertilizer.

Introduction to indoor maintenance of white palm flowers:

White palm is sensitive to temperature, the suitable growth temperature is 14-35 ℃, the optimum temperature is 19-25 ℃, and the temperature difference between day and night is 3-6 ℃, that is, the best temperature is 21-25 ℃ in daytime and 19 ℃ at night. At this temperature, it is beneficial to the absorption and accumulation of nutrients and to the growth and flowering of white palm.

White palm is a kind of flower variety which is sensitive to salt. therefore, the pH value of the substrate should be controlled between 5.2 and 6.1 as far as possible, which is the most suitable for white palm growth. If the pH value is too small, the flower stem becomes shorter, it will reduce the ornamental value. Tap water is suitable for planting white palm, but the price is expensive; natural Rain Water is the best water source in white palm cultivation. The water requirement of potted white palm is different in different growth and development stages.

The principle of regular quantitative application of liquid fertilizer should be grasped. In autumn, 3-4 days is a cycle. If the temperature is high, fertilizer and water can be irrigated once in 2-3 days depending on the dry and wet degree of the substrate in the basin; in summer, fertilizer and water can be irrigated once every 2 days, and once more when the temperature is high; in autumn, fertilizer and water can be irrigated once in 5-7 days.

White palm grows according to the cycle of "leaf → flower → leaf → flower". Inflorescences are formed in the axils of each leaf. This leads to the same yield of flowers and leaves, and the most important factor in the difference in yield is light. If the light is too little, the assimilates produced by the plant under the influence of photosynthesis are also very little; when the light is too strong, part of the leaves of the plant will become warm, which may cause discoloration, burns or scorching of the leaves. Therefore, the success of light management directly affects the number of assimilates produced by white palm and the product quality in the later stage.

The growth of white palm needs relatively high temperature and high humidity, so high temperature and high humidity are beneficial to the growth of white palm. Temperature is closely related to humidity. When the temperature is below 20 ℃, the natural environment of the room can be maintained. When the temperature is above 28 ℃, spray system or atomization system must be used to increase the relative humidity of indoor air in order to create a high temperature and humidity growth environment. However, in winter, even if the temperature in the greenhouse is higher, it is not suitable to cool and moisturize too much, because the plant leaves are too wet at night but reduce their ability to keep out the cold, making it easy to frostbite, which is not conducive to safe overwintering.

Culture methods and matters needing attention of white palm:

1. Illumination: light is very important for plant growth. White palm needs better light in winter and early spring, but it should be shaded gradually when the light is getting stronger. If you enjoy it in the shade, you can't directly expose it to the sun. This is very bad for the growth of white palm.

2. Temperature: White palm is a kind that likes high temperature and should be cultivated in high temperature greenhouse. The lowest temperature in winter should be 14-16 ℃ at night and about 25 ℃ in daytime.

3. Watering: White palm should always keep the basin soil moist during the growth period, but not too much watering, too much basin soil will be moist for a long time, easy to cause rotten roots and plants withered and yellow.

4. Fertilization: do not apply thick fertilizer or raw fertilizer, and water once after applying solid fertilizer, it is best to use thin fertilizer instead of water, so that it generally does not produce fertilizer damage, and white palm will grow luxuriantly.

5. Pests: plants are the most popular pest during the growth period, so special mites should be sprayed regularly to control them, such as dicofol, Nisolan, pyridaben and so on.
