What to do if ivy leaves turn yellow

reason

The influence of light

Ivy is a common green leaf plant in winter. It does not need shade in winter, and it does not matter if the light is slightly stronger. However, the sunlight is strong in summer. If the plant is not moved and continues to receive sunlight normally, it will easily cause necrosis on the leaves.

Effect of temperature

Ivy likes a cool environment and is afraid of stuffiness and frost, especially the early frost in autumn and winter. If it is not moved indoors in time, the leaves will droop and turn yellow due to the frost. In addition, if plants are grown indoors in the summer and ventilation is not timely and the environment is hot and stuffy, yellow leaves will also be caused.

Effect of moisture

The greatest ornamental feature of ivy is its leaves, and the supply of water is the prerequisite for ensuring that the leaves are full. During the growth period, the potting soil needs to be kept moist, but not waterlogged. Many flower lovers do not grasp the degree during the maintenance process, resulting in the potting soil being alternately dry and wet. The plant does not get enough water, the plant metabolism is slow, and the plant has yellow leaves.

Pests and diseases

Pests and diseases are unavoidable during plant maintenance, but in some cases the human eye cannot see the insects on the leaves. If prevention and control are not timely, the leaves of the plants will turn yellow. Or under the influence of leaf spot disease, the plant's leaves may turn yellow without any signs, which is difficult to prevent.

Lack of fertilizer

If ivy leaves keep turning yellow, it may be because it is hungry. When people are hungry, they eat, and when plants are hungry, they need nutrients. When the leaves of the plant turn yellow, it is obviously due to iron deficiency. It is because no fertilizer has been applied for a long time during the maintenance process, or the elements are unbalanced when fertilizing.

what to do

The temperature should be suitable

Since ivy is picky about temperature, satisfy it. After all, you also covet its beauty. Control the ambient temperature at 20~25 ℃, always pay attention to the ambient humidity, and ventilate frequently. The temperature in winter should be controlled above 5 ℃, around 10 ℃ is best.

The light intensity should be moderate

Under suitable light, the leaves of ivy will have uniform shape and bright color. If the plant turns yellow due to light, cut off the severely infested leaves directly, keep the newly grown tender leaves, and give them appropriate light to allow them to recover slowly.

Watering should be done in moderation

During the growing season, the soil should be neither too wet nor too dry (that is, the soil in the pot should not be too wet or too dry). If there is too much water, the roots will rot and the leaves will fall off. Especially in winter when the temperature is relatively low, you should especially control watering. Just keep the soil in the pot slightly moist.

Fertilization should be reasonable

When cultivating ivy at home, the potting soil can be made of rotten leaves or charcoal soil mixed with 1/4 river sand and a small amount of bone meal. A thin cake fertilizer water can be applied once every 2 to 3 weeks during the growing season. Generally, do not apply fertilizer in summer and winter, and when applying fertilizer, be careful not to choose only nitrogen fertilizer. When applying fertilizer, be careful not to contaminate the leaves, so as not to cause them to burn. If the yellow leaves are caused by iron deficiency, you need to supplement the iron in time and water the plants with ferrous sulfate solution.
