Is the Brazilian iron leaf sick like this?

The appearance of macular in Brazilian iron leaves is usually caused by two factors.

One is that the sun is too strong and sunburned. It loves light, but it is not tolerant of bright light. If the light is too strong, the leaves will be sunburned and yellow, so move to a cool place in time and it will recover soon.

The second is the lack of moisture. Although it has drought tolerance, if there is a long-term lack of water, the roots can not absorb water, and the leaves will also turn yellow and have yellow spots.

and sprayed once a week with ammonia sulfate and bika potassium dihydrogen phosphate solution. When the weather is warmer, you can switch to larger pots and switch back to nutritious soil.

The yellowing of Brazilian iron leaves should be caused by improper maintenance, and the common causes are insufficient fertilization, too much sunlight and insufficient watering. If the yellowing of Brazilian iron leaves is caused by insufficient fertilization, it needs to be supplemented with nutrients in time, compound fertilizer can be applied, if it is caused by too much light, it is necessary to move the plant to a cool place to slow down, if it is caused by insufficient watering, immediately replenish the water to the plant, but there can be no stagnant water.

Causes of yellowing of Brazilian iron leaves.

FertilizationDeficiencies:If you don't fertilize it in time, the nutrients will not be timely, and the leaves will slowly turn yellow.

Too much light:If you expose Brazilian iron to the scorching sun when you care for it, its leaves will get sunburned, causing it to turn yellow.

Insufficient watering:Brazilian iron prefers moist environments, and if the plant grows too dry, its leaves will turn yellow due to lack of water.

Brazilian iron leaves are treated with yellowing.

If the yellowing of Brazilian iron leaves is caused by insufficient nutrition, it needs to be supplemented with nutrients in time, compound fertilizer can be applied, if it is caused by too much light, it is necessary to move the plant to a cool place to slow down, if it is caused by insufficient watering, immediately replenish the plant with water, but there can be no stagnant water.

Prevents yellowing of Brazilian iron leaves.

Change the soil and change the pot:When turning the pot, it is best to use humus-rich culture soil for planting, and then add some well-rotted cake fertilizer to ensure that the nutrients are sufficient.

Prevention of pests and diseases:The maintenance of Brazilian iron needs to pay attention to strengthen ventilation, but also in the nymph hatching period with dimethoate or deltamethrin to remove insects, in the high temperature and rainy season spray carbendazim silver imitation to prevent, in winter indoor maintenance, should often open the window ventilation to prevent the harm of the diseased front ciliate.

FertilizationFertilization of Brazilian iron is mainly nitrogen fertilizer, the ratio of nitrogen, phosphorus and potassium is 3:1:1, and 1-2 thin fertilizer can be applied in the growth period, and the fertilization should be stopped in the dormant period, and only water can be watered.

The yellowing of the leaves of the iron tree may be caused by the unsuitable pH of the soil, and the iron tree prefers weakly acidic soil. Plants need sufficient light to photosynthesize during the growth process, producing chlorophyll, and leaves will also turn yellow if there is not enough light. Cultivate iron trees to avoid excessive watering and stagnant water, and do not overdo it when fertilizing.

Yellow leaves can be caused by a variety of reasons, and the following are the treatment measures for several different causes of yellow leaves for reference:

Cut off the yellowed leaves. As long as the rhizome is not dead, it is okay to cut off all the leaves, and after changing the potting soil, place it in a ventilated place with scattered light, maintain a certain environmental humidity, and the iron tree will re-germinate new leaves.

Spray "carbendazim" on the iron tree.

Iron deficiency. If the leaves are yellowed due to iron deficiency, alum fertilizer water should be applied, or ferrous sulfate solution should be sprayed.

Burns. Summer shade protects from the scorching sun.

Freeze. Iron trees are afraid of cold and should have measures to keep warm.

Sullen yellow. The leaves are dull and yellow due to poor ventilation, and they are placed indoors for viewing during the day and moved outdoors at night.

Too wet. Soil that is too wet causes root rot and leaves turn yellow.

The leaves are yellow, not about to die, but about to drown, now there is no way to save in winter, when the weather is hot, change the pot, cut the rotten roots, cut the yellow leaves.
