What do you need to pay attention to how to cultivate and maintain iron trees?

Iron tree is a more common domestic plant, its leaves are evergreen all the year round, vigorous and straight, and if you put it indoors, it can purify the air. So, it is also a good plant. We can often see it outside the hospital, balcony and windowsill, but his breeding process is not simple at all. Let's take a look at it.

First, how to raise the iron tree to live well

1. Soil: potted iron tree is suitable for slightly acidic sandy soil with good drainage, loose and fertile soil.

2. Temperature: the iron tree likes to be warm, so it should be cooled by spraying water properly when it is hot in summer, and the room temperature should be kept at about 10 ℃ in winter. As the growth of the iron tree is relatively slow, the hot sun should be avoided in summer, otherwise it is easy to cause the phenomenon of scorched leaves and yellow leaves. The iron tree has strong cold resistance, but when the winter temperature is 0 ℃, it should move indoors or in a warm place to survive the winter.

3. Light: the iron tree can not be placed indoors for too long, because the iron tree likes the light, and the lack of light will make its new leaves sparse, thin and green. Therefore, the four seasons of iron tree breeding need to be placed in a sunny place, especially when new leaves grow in spring and autumn, they should be maintained in direct sunlight, and then move indoors to watch when the new leaves grow old.

4. Watering: the principle of dry and wet should be mastered in watering. In winter, if the room temperature is lower, the growth stops and is in a semi-dormant state, and the water should be watered less.

5. Soil: suitable for growing in loose, fertile, well-drained sandy loam. Potted Brazilian wood can be cultivated by mixing vegetable garden soil, rotten leaf soil, peat soil, river sand according to 3, or fertile pond mud, dried and finely crushed, and coarse river sand 3.

Second, what should be paid attention to in maintaining the iron tree

1. Pruning

The growth of the iron tree is relatively slow, with only one round of leaves every year. Every time the new leaves unfold and mature, the old leaves in the lower part are cut off and the leaves in 2 to 3 rounds are kept without frequent pruning. Even if you transplant or change the basin, you don't need too much pruning. When the leaves are affected by diseases and insect pests, the natural environment is bad and yellowed and dry, so it should be cut off in time.

2. Diseases and insect pests and their control

The main results are as follows: (1) spot disease, which is a fungal ☆ prohibited ☆ disease. After the leaf is infected, it is a small light brown spot at the beginning, and then spreads into a nearly round or irregular shape, with a diameter of 1 mm to 5 mm. The center of the disease spot is dark brown to gray-white, the edge is reddish brown, and there are black spots on the disease spot. A section of spot is formed due to the connection between the disease spots, causing the leaves to die and break. In high temperature and rainy weather, the disease is easy to spread. In the aspect of prevention and control, the cultivated soil should be suitable for slightly acidic sand, more water should be drenched in summer, and diseased old leaves should be removed in time. At the initial stage of the disease, spray Bordeaux liquid or 75% chlorothalonil wettable agent 600x liquid, or 50% topazine wettable powder 800x to 1000 times liquid, or potassium permanganate 1000 times liquid, about 10 days spray, the effect is better.

(2) when the shell insects are planted and maintained on the balcony, the ventilation and light transmittance is not good enough, and the leaves are often vulnerable to the shell insects. At the initial stage of the disease, there are the following prevention and treatment treatments: ① repeatedly gently rubbed the injured leaves with alcohol to kill adults and larvae. ② soaked rice vinegar with cotton balls and gently rubbed the damaged leaves, which could wipe off the shell insects and make the leaves green again.
