What if the latest ivy leaves turn yellow?

Ivy is a common foliage plant in southern China. Because it is evergreen all the year round, it is often used as vertical greening in the south. It can also be planted indoors with potted plants, and can maintain evergreen color even in winter. But if the farmed ivy leaves turn yellow, then its ornamental value will be greatly reduced. Below, the pro-farm network will introduce to you how to do the ivy leaves yellowing.

First, the reason for the yellowing of ivy leaves

First of all, let's take a look at the causes of the yellowing of ivy leaves. Usually, the leaves of plants turn yellow because we do not have the right methods in the process of breeding. Here, the pro-agriculture network summarizes five factors that will lead to the yellowing of ivy leaves. Let's take a look at the details.

1. Light

Ivy is a negative vine, the light is not strong in winter, there is no need to shade the ivy, can accept all-day sunlight. But the summer sun is strong, if it does not move, it is still normal to receive sunlight, which is easy to cause foliar necrosis.

two。 Temperature

Ivy is a plant that prefers a cool environment, but it is not resistant to freezing, especially in autumn and winter mornings. If the ivy is not moved indoors in time, the leaves will droop and turn yellow due to frost. There is ivy can not bear muggy, summer indoor breeding, if not timely ventilation, muggy environment, will also cause yellow leaves.

3. Moisture content

The main ornamental value of ivy is reflected in the leaves, and water is the premise of full leaves. The growing period of ivy should ensure that the basin soil is moist and often watered, but not stagnant water. If you do not grasp the amount of water well in the maintenance, the basin soil will be dry and wet, and the plant will not get enough water, so the growth and metabolism of ivy will become slow, and the leaves will turn yellow.

4. Fertilizer

Fertilizer is to plants what rice is to human beings. If there is no fertilization at all or the elements of fertilization are not balanced during the growth of ivy, then the plant will grow poorly due to lack of nutrition. If the leaves of ivy turn yellow, it is probably caused by the lack of iron.

5. Diseases and insect pests

The impact of diseases and insect pests is different from the above factors, virus is an unavoidable problem in the process of plant conservation, and very often people's naked eyes can not find bugs on plant leaves at all, if the prevention and control is not timely, by the time it is found, it may already be a large area of yellow leaves. At the same time, plant leaf spot disease may also lead to plant yellow leaves, and usually at this time the plant will not have any signs of yellow leaves, people are difficult to prevent.

Second, the treatment of yellowing of ivy leaves

We already know that there are several reasons why ivy leaves turn yellow, so let's explain the corresponding solutions according to the reasons.

1. Suitable temperature

Ivy is picky about temperature, so we should try our best to satisfy it when we breed it. The usual ambient temperature is controlled at 20-25 ℃. At the same time, we should also pay attention to the ambient humidity and ventilation. In winter, the temperature should be controlled above 5 ℃ and 10 ℃ as far as possible.

two。 Moderate lighting

Under suitable light, the leaves of ivy will be consistent in shape and bright in color. If the plant turns yellow due to light, the serious leaves will be cut off directly, and the newly grown young leaves will be retained and given appropriate light to make them recover slowly.

3. The right amount of water

In the growing period of ivy, it is necessary to keep the basin soil moist, but do not form stagnant water, and do not let the basin soil be too dry at the same time. If there is too much water, the roots and leaves will rot. Especially in winter, the temperature is on the low side, so it is especially necessary to control watering, as long as the basin soil is a little moist.

4. Reasonable fertilization

When planting ivy, you can choose rotten leaves or river sand with a small amount of bone powder, and apply thin pancake fertilizer and water once in 2 to 3 weeks during the growing period of ivy. There is usually no fertilization in winter and summer. The elements of fertilization should be controlled reasonably, not only nitrogen fertilizer should be added, and attention should be paid not to defile the leaves in the process of fertilization, so as not to cause the leaves to scorch. Yellow leaves caused by iron deficiency can be restored by adding ferrous sulfate to the soil.

The above are the reasons and treatment methods for the yellowing of ivy leaves sorted out by the pro-agricultural network, hoping to bring some help to you. In addition to ornamental effects, ivy also has a certain medicinal value. At the same time, ivy symbolizes unflinching emotion and is very suitable for marriage.
