Ecological Habits of queen palm

Queen palm likes a warm, moist, sunny and ventilated environment. Its growth temperature is 22-28 degrees Celsius, and it can withstand the low temperature of -2 degrees Celsius and the low temperature of -5 degrees Celsius for a short time. Queen palm requires fertile and moist soil, strong wind resistance, salt and alkali resistance and drought resistance.

Queen palm prefers warm, moist and sunny environments, requiring a deep soil layer, loose soil quality and good drainage. Its growth temperature 22-28 degrees, can withstand the low temperature below 0 degrees. Less occurrence of diseases and insect pests. Queen palm is resistant to hot sun, also slightly shade. Queen palm is a pleasant soil layer deep, fertile moist as the base fertilizer, every year to apply nitrogen fertilizer 1~2 times, can keep the leaf green, and does not appear dry yellow. Spring, summer, autumn 3 seasons should cover the sun 50% or so, not in strong sunshine under the direct bask, otherwise can make blade dry edge, coke tip, lose ornamental value.In winter, it can be placed indoors in direct sunlight.

Queen palm is beautiful in shape, prefers shade, and likes warm and moist environments. The soil must be moist during the growing season and there must be adequate air humidity around the plant. Queen palm with loose tails are afraid of the cold and have poor cold resistance. Potted Queen Palm placed in the shade on the open ground must be moved indoors in late September for the winter season

It is better to keep the room temperature at about 25℃ in the daytime, and the room temperature at night should be kept above 15℃, or at least above 10℃. If it is lower than 5℃ for a long time, it will be subjected to freezing damage. During the winter, we must also pay attention to often scrub the foliage or spray a small amount of water to the foliage, to clean the foliage, keep the foliage fresh and bright to improve the ornamental effect.

How to grow and care for queen palm

[Soil] : Queen palm has strong growth potential, developed root system, soil conditions are not strict requirements, potted, available Garden soil and humus soil equal amount of mixing as a substrate.

[Temperature] : The suitable temperature for Queen palm growth is 18-30 degrees, and the overwintering temperature is 3 degrees. Queen palm can bear the low temperature of -1 -- 2 degrees for a short time, and it will be subjected to freezing damage if the temperature is lower than this for a long time.

[Light] : For light-loving plants, the growing period should be full of sunshine, Queen palm has a strong ability to adapt to the light, and is also suitable for indoor light cultivation and ornamental.

[Watering] : The root is half fleshy, Queen palm has a strong drought resistance ability, in 3-October growing season, can be watered 1 times a day, other seasons watering to grasp the dry and wet moderate, avoid basin soil water, so as not to cause root rot. Just keep the soil moist during dormancy, and spray water on the leaves in dry climates to ensure that the leaves are dark green and shiny.

[Fertilization] : During the growing period, liquid fertilizer or compound fertilizer is usually applied every month 1-2 times to promote the vigorous growth of plants.

[Potting and repotting] potted or for pot, add a small amount of decaying cake fertilizer as the base fertilizer, every 15 days during the growing season, stop fertilizing after the beginning of autumn; Queen palm grows fast and has developed root system, so it should be changed once a year in early spring. During the change, part of the old roots should be cut off, the old yellow leaves at the base of the plant should be cut off, and some new culture soil should be replaced, which is conducive to growth.

Queen Palm Winter Care for Young Plants Young palms are especially vulnerable to cold damage because they haven’t developed deep enough root systems to ensure the base of the plant survives. Plants in containers can be brought indoors for winter. Those in the ground should be mulched around the base. For extra protection when a freeze is due, put a bucket or garbage can over the crown with holiday lights inside. The lights emit just enough warmth and the covering keeps heavy snow and icy winds from the fronds. How to Overwinter Queen Palms Winterizing queen palm trees is essential if your region ever expects freezing temperatures. The young plants are easy to protect, but the big mature beauties are much more difficult. Holiday or rope lights help add ambient warmth. Wrap the trunk and the fronds. To make this more effective, build a scaffold around the plant. Then you can cover the entire plant in frost barrier fabric. This is an important part of queen palm winter care where even an extended frost can cost the plant much of its vitality. A product also exists that is a spray on protection. Whichever method you choose, follow in late summer to early fall with an appropriate fertilizer. Well-nourished trees are much hardier than nutrient deprived tissues.

Queen Palm is usually divided every three years or so. In spring with change of soil in the basin basin, from within the basin of the original tuo ke to soil, shake off the soil Chen, choose tillering more plants, with a sword or branches cut from the base joint will be divided into plant plexus, mature had better have two or more tillers buds, and maintain a beautiful shape, the basin respectively, placed in 20 ℃ about indoor, after 1 to 2 years of careful maintenance, can become the new plants.
