The leaves of the longevity flowers of the unit turned yellow and only after investigation did they know that it was because they did not open the window.

When I was in the company a few days ago, the manager was admiring the flowers in the company, pointing to the unflowering plants and asking what kind of flowers they were and why the leaves were yellow. When Huahua passed by later, it was found that the leaves of Catharanthus roseus had turned yellow.

So Huahua hurriedly thought about what went wrong and made the leaves of Catharanthus roseus change. It doesn't matter if the leaves turn yellow, it will be fine if you take care of them slowly. Don't let the leaves continue to turn yellow, which may affect the blooming of longevity flowers in the future. Does it sound a little wrong for longevity flowers that do not blossom?

First of all, Huahua first observed the leaves of longevity flowers to see if there were any insect pests. We should know that if longevity flowers attract pests, those pests will slowly absorb the branches and leaves of the leaves, resulting in the phenomenon of yellowing and withering of the leaves. I looked at the leaves, but fortunately there were no pests.

Then Huahua thought about whether the longevity flowers had not been watered recently, but someone in the company would water the plants on time every day, so this problem should not occur. However, Huahua still needs to remind everyone that longevity flowers are not resistant to waterlogging, so they are usually watered as little as possible, and it can be troublesome if there are rotten roots. If the leaves of longevity flowers turn yellow because of too much watering, the water can only be poured out and left in a cool place to dry.

It's not a problem of watering, is it possible that it's a problem of fertilization? Recently, plants are not often fertilized in the company, ah, this can be eliminated. If too much fertilizer is applied to the longevity flowers, the leaves will turn yellow, basically because too much fertilizer will burn the roots of the longevity flowers, the roots will be hurt, and the leaves will naturally turn yellow, resulting in a corresponding reaction. Therefore, we must pay attention to the fact that when applying fertilizer, we must dilute the fertilizer and then fertilize the plant, otherwise the plant will die.

Could that be a shade problem? Probably not. Although the flowers in the company are placed next to the windowsill, there is a building in front that blocks part of the sun, so it can be regarded as a place for astigmatism. This kind of astigmatism does not turn the leaves of longevity flowers yellow, only when the sun shines strongly in summer.

If none of the above is the reason, then it can only be the problem of ventilation. As it is not yet completely autumn, the company still turns on the air conditioner and closes the window every day. As soon as the air does not flow, the plants will inevitably "get sick", so the cause of the problem has finally been found. It is because there is no ventilation. Now the flowers know the reason, and quickly change the longevity flowers to a ventilated place.

After this incident of yellowing the leaves of longevity flowers, have you learned anything with Huahua? No? Just watch it a few more times!
