What is the yellowing of the leaves of the iron tree?

Iron tree an ancient evergreen plants, potted words not only high ornamental value, long life, but also has a good effect of greening and beautifying the environment, so the application range of iron tree is also very wide. However, if we usually provide poor conservation environment or improper management, the plant is also more prone to yellow leaf phenomenon. So, what's with the yellow leaves?

There are many incentives for the yellowing of the leaves of iron trees, and the new leaves and the old leaves appear yellowing, and the reasons are different. We need to investigate according to scientific methods, and then make corresponding corrective measures, so that the yellow leaves can be improved and eliminated, so that the plants can return to normal growth and return to the good viewing posture of the past.

1. Alkalization of basin soil

Iron tree likes fertile loose, breathable water permeability strong slightly acidic soil environment, if the pot soil gradually alkalized, then the plant can not grow normally in such soil, so the plant in poor growth, more likely to appear yellow leaves. Then, we can apply a little ferrous sulfate solution to the plant when loosening the soil, and dilute it according to the ratio of 1:500. At the same time, keep watering once a week, and continuously carry out 3-5 times to improve the yellowing of leaves.

II. Improper lighting

Although iron tree is a kind of growth environment that likes warm and sufficient light, it is easy to cause excessive growth when the original light is insufficient, and it will also cause yellowing of the leaves, but if the light intensity is too high in summer, it will also cause its leaves to be burned and yellow. Therefore, in addition to proper shade in summer, other seasons should be allowed to bask in the sun, so as to avoid yellow leaves.

III. Improper watering

Many flower plants will be due to excessive watering caused by rotten roots and plants appear yellow leaves, for iron trees such as succulent roots of plants, often more sensitive to watering. When watered excessively, rotten roots will appear, thus causing the leaves to gradually turn yellow and wither. If the young leaves are yellow, water should be controlled in time; but if the pot is short of water for a long time, it will also make the old leaves of the plant turn yellow. Therefore, we need to judge whether the plant is overwatered or short of water according to whether the young leaves or the old leaves are yellow.

IV. Excessive fertilization

Although iron tree likes fertile pot soil environment, but at the same time its root system is fleshy root, improper fertilization is also easy to cause fertilizer damage, when the root system is damaged, the plant will appear yellow leaves. Therefore, you can use a little slow release fertilizer as a base fertilizer when you put it on the pot, and then apply a thin organic fertilizer or compound fertilizer once a month in the normal growth season, and try to achieve "thin fertilizer and frequent application".

5. Iron deficiency element

If there is a lack of iron in the pot soil, then the leaves of the iron tree will appear iron-deficient yellow, so we need to supplement some nutrients in time, mainly iron. Usually ferrous sulfate can be used, add appropriate amount in water, fully dilute and stir well and spray it in the basin soil. In this way, after the iron tree gets enough iron, the yellow leaf phenomenon will gradually disappear.

VI. Disease and insect infestation

Iron tree in the growth process is more vulnerable to red spider attack and cause yellowing leaves, of course, by disease infestation will be the case. Once the plant is infected with pests and diseases, the affected leaves should be cut off in time, and then the plants should be treated with pesticides and insecticides. At the same time, it is necessary to improve the conservation environment in time, because most of the plant diseases and insect pests are caused by poor conservation environment. After a period of maintenance, the plant grows new leaves and turns green.
