The leaves of the "kalanchoe" in the unit turned yellow. After investigation, we found out that it was because the windows were not opened!

So Huahua quickly thought about whether there was something wrong that caused the leaves of Catharanthus roseus to change. It doesn't matter if the leaves turn yellow. They will be fine if you take good care of them. Don't let the leaves continue to turn yellow, as this may affect the future flowering of the Kalanchoe. Doesn't it sound a bit wrong to have a Kalanchoe that doesn't bloom?

First of all, Huahua observed the leaves of the Kalanchoe to see if there were any insect pests. You should know that if the Kalanchoe is infested with insect pests, those pests will slowly suck the leaves and branches, causing the leaves to turn yellow and wither. I looked at the leaves and luckily there were no insect pests.

Then Huahua thought again that it might be because she hadn't watered the Kalanchoe recently, but there was someone in the company who watered the plants on time every day, so this problem shouldn't occur. However, Huahua still needs to remind everyone that Kalanchoe is not a waterlogged plant, so try to water it as little as possible. If root rot occurs, it will be troublesome. If the leaves of the Kalanchoe turn yellow due to overwatering, you can only pour out the water and place it in a cool place to dry.

If it's not a watering issue, could it be a fertilization issue? I haven’t been fertilizing the plants regularly in the company recently, so this can be eliminated. If you fertilize the Kalanchoe too much, its leaves will turn yellow. Basically, it is because too much fertilizer burns the roots of the Kalanchoe. The roots are damaged, so the leaves naturally turn yellow, resulting in a corresponding reaction. So everyone must pay attention and dilute the fertilizer before fertilizing the plants, otherwise the plants will die.

Would that be a shade issue? I don't think so. Although the flowers in the company are placed next to the windowsill, the building in front blocks part of the sunlight, so it can be considered a place with scattered light. This kind of scattered light will not make the leaves of Kalanchoe turn yellow, only the strong sunlight in summer will do that.

If none of the above reasons are correct, then it can only be a ventilation problem. Since it is not yet fully autumn, the air conditioner is still turned on and the windows are closed in the company every day. Once the air does not flow, the plants will inevitably get "sick", so the cause of the problem was finally found. It turned out that it was because of lack of ventilation. Now Huahua knew the reason and quickly moved the Kalanchoe to a ventilated place.

After this incident of the leaves of the Kalanchoe turning yellow, have you learned anything with Huahua? No? Then watch it a few more times!
