Conservation and management of Brazilian wood potted plants

Brazilian wood

Brazilian wood produced natural variation in the process of cultivation, and striped spots appeared on the leaves. The sword leaf dragon blood tree with red edge; the dragon blood tree with green leaves in the center and silver edges on both sides; the Venus dragon blood tree with irregular spots on the green leaves; the golden heart dragon blood tree with several yellow vertical markings on its leaves; the tiger blossom tree with dark green and gray horizontal stripes in its leaves; and the dragon blood tree with dark green mixed with several white stripes, and so on. But the most common ones are Phnom Penh Brazilian wood and silver-edged Brazilian wood.

There is plenty of sunshine

Brazilian wood likes to be warm and humid, which requires sufficient sunshine and should not be placed in a dark place, otherwise the leaves will have no luster and lose their ornamental value. However, Brazilian wood can not be exposed to direct sunlight for a long time, 50% shading is appropriate in summer, spring and autumn can accept direct light in the morning and evening, and there is no need to shade in winter. If the environment is too overcast, the leaf color is green and the glossiness is low; if the light is too strong, it is easy to burn the leaves by the scorching sun. Brazilian wood in the cultivation process, if the yellow lines of the leaves fade, it is due to the indoor light is too dark, proper exposure to the sun can be changed.

Timely watering

The soil planted with Brazilian wood should be kept moist, but it should not be flooded, otherwise the roots will rot. Due to exuberant growth and large water consumption, Brazilian wood is prone to water shortage. Therefore, attention should be paid to timely watering. In normal weather, it is necessary to be fully watered once a day, and the air humidity is required to be 80%. High temperature and high humidity are conducive to its rapid growth. However, too much or too little watering will lead to root rot, drooping leaves and dull leaves, so the rotten roots should be removed. If the bottom stake is rotten, it can be sawed off, soaked in 0.2% potassium permanganate water for 10-30 minutes, and buried in a well-drained matrix soil. If the leaf is scorched or dry, it is caused by air dryness and can be improved by spraying water to the leaf surface.

Soil fertilizer conservation

The basin soil requires a certain amount of water and fertilizer, aerated and loose soil. Generally, coconut bran and river sand are mixed with 6 ∶ 4, or peat soil and river sand are mixed with 1 ∶ 1. Change the basin every two years to renew the root system and enhance its vitality.

Brazilian wood is a foliage plant, so the proportion of nitrogen fertilizer should be slightly heavy, usually apply nitrogen, phosphorus, potassium full-effect compound fertilizer once a month, while external application of potassium dihydrogen phosphate plus urea 0.2% 0.3% aqueous solution 2-3 times. For the varieties with golden or silver spots, we should apply more phosphate and potassium fertilizer and less nitrogen fertilizer, too much nitrogen fertilizer will lead to excessive plant growth and leaf color turning green, and reduce the ornamental value.

Suitable temperature to keep warm

The suitable temperature for Brazilian wood growth is 20 ℃-25 ℃. Brazilian wood can grow when the indoor temperature is not lower than 18 ℃; if the temperature is lower than 13 ℃, it will go into dormancy. The temperature is too low, because the root system is difficult to absorb water, the evaporated water of the leaf can not be replenished in time, which can easily lead to chloasma on the leaf edge and reduce its ornamental value. Winter room temperature should be kept between 6 ℃-10 ℃, if the indoor temperature is too low, and the air is dry, the lower leaves will turn yellow and scorch edges, and even part of the leaves will die; if the heart of the leaf buds blacken and rot gradually, it is due to low temperature, mostly caused by frost injury; if the skin of the stake is not rotten, it can also be moved to a high temperature place to send new buds and remove the old buds to renew.

Disease prevention and cure

The main diseases and insect pests of Brazilian wood are stem borer. Among them, the sugarcane moth and longicorn beetle pests feed on the larvae in the upper and lower cortex of the stem, and when they are light, they will appear insect tracks and a small amount of insect feces will be excreted; in heavy cases, the endoplasmic part of the epidermis will be eaten up, and finally the branches and leaves will wilt and turn yellow gradually, thus losing the ornamental effect of foliage plants. Move the Brazilian wood to an outdoor cool place, spray or pour with 1000 times omethoate once a week, three times in a row, or use pesticides to form 1-∶ poisonous soil and spread it evenly on the surface of the basin soil to kill pests. Anthracnose and other diseases that occasionally appear on leaves can be effectively prevented by spraying 75% wettable powder chlorothalonil or 85% topiramate 800 times.

Pot conservation and management of Brazilian trees Brazilian trees, also known as Brazilian iron trees and dragon blood trees, are evergreen trees of the genus Liliaceae and dragon blood trees. Dragon blood tree is native to Africa, Guinea and other tropical regions, and was first introduced and operated by South American Brazilians. Its stem is thick and straight, the leaves are clustered with stem items, the bright leaves are broadband-shaped, the upper part is slightly bent, and the whole plant has a beautiful shape, coupled with a sexual preference for semi-shady environment, which is very suitable for indoor pot cultivation.

Brazilian wood produced natural variation in the process of cultivation, and striped spots appeared on the leaves. The sword leaf dragon blood tree with red edge; the dragon blood tree with green leaves in the center and silver edges on both sides; the Venus dragon blood tree with irregular spots on the green leaves; the golden heart dragon blood tree with several yellow vertical markings on its leaves; the tiger blossom tree with dark green and gray horizontal stripes in its leaves; and the dragon blood tree with dark green mixed with several white stripes, and so on. But the most common ones are Brazilian wood in Phnom Penh and Brazilian wood in silver.

Brazilian wood likes to be warm and humid, which requires sufficient sunshine and should not be placed in a dark place, otherwise the leaves will have no luster and lose their ornamental value. However, Brazilian wood can not be exposed to direct sunlight for a long time, 50% shading is appropriate in summer, spring and autumn can accept direct light in the morning and evening, and there is no need to shade in winter. If the environment is too overcast, the leaf color is green, the glossiness is low, and if the light is too strong, it is easy to burn the leaves by the hot sun. In cultivation, the yellow lines of the leaves fade because the indoor light is too dark, which can be changed by proper exposure to the sun.

The soil in the flowerpot where Brazilian wood is planted should be kept moist, but it should not be flooded, or the roots will rot. Due to vigorous growth, large water consumption, easy to appear water shortage phenomenon, should pay attention to timely watering, normal weather should be fully watered once a day, space or ground sprinkler 2 to 3 times, air humidity requirements of 80%, high temperature and humidity is conducive to its rapid growth. Too much or too little watering will lead to root rot, drooping leaves and dull leaves. The rotten root should be removed at this time. If the bottom stake is rotten, it can be sawed off, soaked in 0.2% potassium permanganate water for 10 to 30 minutes, and buried in a well-drained matrix soil. The leaf edge is scorched or dry, which is caused by air dryness, and can be improved by spraying water to the leaf surface.

The basin soil requires a certain amount of water and fertilizer, aerated and loose soil. Generally, the best mixture of coconut bran and river sand is 6 ∶ 4, or the mixture of peat soil and river sand is 1 ∶ / l. Change the basin every two years to renew the root system and enhance its vitality.

Because it is a foliage plant, the proportion of nitrogen fertilizer should be slightly heavy, and the full-effect compound fertilizer of nitrogen, phosphorus and potassium should be applied once a month, while potassium dihydrogen phosphate + urea 0.2% to 0.3% aqueous solution should be applied outside the root for 2 to 3 times. For the varieties with golden or silver spots, more phosphate and potassium fertilizer should be applied, and less nitrogen fertilizer should be applied. Too much nitrogen fertilizer will lead to excessive plant growth and leaf color turning green, and reduce the ornamental value.

The suitable temperature for its growth is from 20 ℃ to 25 ℃. When the indoor temperature is not lower than 18 ℃, Brazilian wood can grow, and if the temperature is lower than 13 ℃, it will go into dormancy. The temperature is too low, because the root system is difficult to absorb water, the evaporated water of the leaf can not be replenished in time, which can easily lead to chloasma on the leaf edge and reduce its ornamental value. In winter, the lowest room temperature should be kept between 6 ℃ and 10 ℃. If the indoor temperature is too low and the air is dry, the lower leaves turn yellow and scorched edges, and even some leaves die. If the heart of the leaf bud blackens and gradually rotten, it is due to the low temperature and is mostly caused by frost injury. If the skin of the stake is not rotten, it can also be moved to a high temperature to send out new buds and remove the old buds to renew.

The main diseases and insect pests are stem borer. Among them, the sugarcane moth and longicorn beetle pests feed on the larvae in the upper and lower cortex of the stem of the wooden stem. when it is light, it will appear, and a small amount of insect feces will be excreted, and when it is heavy, the endoplasmic part of the epidermis will be eaten up, and finally the branches and leaves will wilt and turn yellow gradually. lose the ornamental effect of foliage plants. Move the Brazilian wood to an outdoor shade and spray or pour it with 1000 times omethoate, once a week, three times in a row. The poisonous soil made of 1 ∶ 200with insecticides can also kill pests by spreading it evenly on the surface of the basin soil. For some diseases such as anthracnose that occasionally appear on leaves, they can be effectively prevented by spraying with 75% wettable powder chlorothalonil or 85% topiramate 800 times.
