Why Are the Leaves of the Baby Rubber Plant Turning Black? Causes Explained
The baby rubber plant (Peperomia obtusifolia) is an ornamental plant with fairly high ornamental value. It is now mainly grown as a potted plant and is widely distributed in China. Because of its high ornamental value, it is also very popular with many people. However, when growing the baby rubber plant, many problems often arise that affect its growth. One of them is the leaves turning black. So why do the leaves of the baby rubber plant turn yellow? Below, the editor will give you a brief introduction. Let's take a look!
1. Improper watering
During its growth, the baby rubber plant has a fairly high demand for water. The baby rubber plant generally also likes to grow in a relatively moist environment, but when watering, we should pay attention to controlling the amount of water. If too much water is given and water accumulates in the soil, it will hinder the breathing of the baby rubber plant's roots, leading to root rot. Moreover, when watering, if the water temperature is too cold, it can also easily cause the leaves of the baby rubber plant to turn black. Therefore, pay attention to the amount of water given. If water accumulates, drain it promptly to avoid root rot from too much water.
2. Improper fertilizing
When growing the baby rubber plant, fertilizing work is also very important. A reasonable fertilizing method is crucial to the growth of the baby rubber plant, but when fertilizing, if the amount of fertilizer is not properly controlled and too much is applied, or if farmyard manure that has not been fully decomposed is applied, it will cause fertilizer burn to the roots, so that the baby rubber plant cannot grow normally and its leaves turn black. So when fertilizing, we should not only strictly control the amount of fertilizer, but also make sure the organic fertilizer is fully decomposed. If too much fertilizer is applied, water promptly to dilute the fertilizer.
3. Unsuitable temperature
Temperature is also one of the main causes of blackened leaves on the baby rubber plant. The baby rubber plant does not like to grow in a high-temperature environment, especially in summer, when high temperatures are very unfavorable to its growth. If it is kept in a high-temperature environment for a long time, black spots will begin to appear, and in severe cases the leaves will rot. But the temperature should not be too low either, as too low a temperature will cause frost damage to the leaves and make them turn black. Therefore, be sure to control the temperature well. Especially in summer and winter, pay attention to ventilation and cooling, and to cold protection and warmth.
4. Too much light
The baby rubber plant is also fairly poor at tolerating strong light. When growing it, pay attention to creating a low-light environment for it. If the baby rubber plant is kept in direct strong light for a long time, its leaves are very easily sunburned and turn black. So light control is also very important. Do not let the baby rubber plant receive direct sunlight, especially in summer. However, it should not be kept in a dark, low-light environment for a long time either; it should also be given an appropriate amount of scattered light.
The above is a brief introduction to why the leaves of the baby rubber plant turn black. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
