How to cultivate and manage white palm
Today, the editor will explain how to cultivate and manage white palm and the related introduction of green plant flowers, such as the cultivation methods of potted white palm. Please see the detailed introduction below.
White palm, also known as Spathiphyllum, commonly known as "Smooth Sailing", has the flower language of beauty, purity, virtue, friendship, and confidence. The flowers of white palm are graceful and pure white, considered as the "flower of purity", so it is believed in folk that Spathiphyllum has an auspicious meaning. Due to its vigorous growth and shade tolerance, it is deeply favored by people and often seen as a potted plant indoors.
Key points for daily maintenance of white palm:
Point 1: Light
It is best to keep white palm in a place with diffused light, and the lighting conditions in most family rooms are particularly suitable for growing white palm. Specifically, winter and early spring require good lighting and should not be shaded; in late spring, as the temperature and light intensity increase, gradually provide shade until the end of autumn, when the temperature drops. If it has been maintained in a shaded area, it should not be suddenly exposed to direct sunlight, as this may cause the plant to wilt or turn yellow due to the sudden change in environment and sensitivity to strong light, and may even lead to death.
Point 2: Temperature
White palm is a plant that originally grows in subtropical and warm temperate regions, preferring warm conditions throughout the year. The most suitable temperature range is between 15-30°C. When the temperature drops below 5°C, it is necessary to prevent cold and keep warm, otherwise the leaves may freeze and wilt; when the temperature exceeds 35°C, the leaves may dry out and lose vitality.
Point 3: Humidity
White palm requires a higher level of air humidity. If the air is too dry, it can cause the leaves to turn yellow and lose their luster. This can be solved by spraying water on the leaves or sprinkling water on the ground. Covering with a transparent plastic bag is also an option, but it should be slightly ventilated or a hole should be made in the top of the bag during high temperatures and good lighting to prevent the temperature inside the bag from rising sharply, which could cook the leaves of the white palm.
Point 4: Fertilization
White palm prefers thin fertilizer and should not be fertilized with thick or raw fertilizers. Generally, a little base fertilizer is applied when repotting, or a little dilute liquid fertilizer is added in spring and autumn. It is best to use compound fertilizers, not just nitrogen fertilizers, as this may prevent flowering.
Point 5: Common pests
The most common pests are red spiders, scientifically known as "mite damage", which cause the leaves to wilt, lose luster, and turn yellow-brown. Miticides such as dicofol, nissorun, and pyridaben can be sprayed for control.
Point 6: Common diseases
Common diseases include bacterial leaf spot and root stem rot. For leaf spot disease, a 500-fold dilution of carbendazim wettable powder can be sprayed on the leaves. For root stem rot, in addition to ensuring ventilation and reducing watering and humidity, a 800-fold dilution of metalaxyl wettable powder can be sprayed on the leaves and poured into the potting soil to control the disease.
Reasons why white palm does not bloom:
The main factor affecting the non-blooming of white palm is insufficient light. Since white palm is usually potted and kept indoors, insufficient light is an easily overlooked problem. If this is the reason for non-blooming, the solution is simple: move it to a place with sufficient light, such as gradually moving it closer to the window sill.
How to cultivate and manage white palm
▲White palm lacking light
If you want white palm to bloom, you need to induce it. In addition to the factor of insufficient light, if white palm still does not bloom, certain induction is needed. The specific method is to spray gibberellic acid, and the plant can bloom after a month or two of spraying. Note that the concentration of gibberellic acid should not be too high, with a 1000-1500-fold dilution in water. High concentration can cause flower deformation.
Why are some flowers of white palm green?
Conventionally, the flowers of white palm are white, red palm has red flowers, and pink palm has pink flowers. So why do some white palm flowers turn green sometimes?
There are mainly two reasons: the first is that as the flower ages, the color gradually deepens, eventually turning green like leaves, which is a normal situation; the second is the influence of light. If the maintenance environment lacks light, the color of the white palm flowers will be deeper, and moving it to a place with sufficient light will gradually make the color white.
How to solve yellow leaves on white palm?
When white palm does not bloom, the main attraction is its leaves, which are green and broad with patterns, providing certain ornamental value. If the leaves turn yellow, it is mainly due to insufficient light, humidity, and nutrition.
1. Influence of light: Depending on the season, if the leaves turn yellow in summer, it is definitely due to too much light, and it needs to be moved to a more shaded place. If it's winter, it may be due to insufficient light, and it needs to be gradually moved to a warm and sunny place.
2. Influence of humidity: White palm prefers humidity. If the air is too dry, not only will the leaves turn yellow, but they will also lose their luster and appear grayish. In this case, we can use a spray bottle filled with water to spray the leaves or the surrounding air, as many times as needed throughout the day.
3. Insufficient nutrition: White palm needs to be repotted once a year, and additional water fertilizers should be applied during the growing season and flowering period.
