What about the yellow leaves of carnations

There is a friend who has bought flowers for nearly a month. He will water them every few days. So far, he has fattened them twice. He usually puts them on the balcony and takes them into the living room at night. However, in recent weeks, it has rained every day and there is no sun, but the leaves suddenly turn yellow. Today, let's take this problem as an example to see how carnations turn yellow. What about it?

I. reason for yellow

1. Improper watering

2. The nutrition is alkali.

It likes a little acid soil, if you often give it some water containing alkali or the soil planting flowers also have alkali flowers, the leaves will be hurt naturally

3. No flowerpot or soil has been changed for a long time.

At the beginning of the article, the friend spent only one month, which should not belong to this situation. But if your flower has been bought for a long time, and you haven't changed the flowerpot and soil, and the leaves have turned yellow, it's probably caused by this situation. The nutrition of flowers planted in this way can't keep up, and there's not a lot of nutrients for the roots to absorb, and the leaves will be short of nutrients.

4. Improper light and temperature

When the temperature is higher than 30 ℃, the leaves will dry easily and turn yellow. If the light is not enough, the leaves can't breathe and photosynthesis, they will turn yellow.

The above several reasons sometimes occur alone, most of the time at the same time, according to the specific situation of the leaf to analyze what is the reason
