Reasons for Yellowing Leaves on the Air Plant (Bryophyllum) and Solutions

The air plant (Bryophyllum pinnatum, also known as the cathedral bells plant) is native to Africa, and it is now cultivated in various parts of our country. Besides its ornamental value, it can also be used as a Chinese medicinal herb, with effects of detoxifying and reducing swelling, promoting blood circulation and relieving pain. This plant is called "falling to the ground and taking root" because as long as you pick off its leaves and lay them flat on damp sand, they will soon take root and survive, hence the name. But even a plant with such strong vitality can develop yellow leaves. Below, Qinnong Network will explain what to do when the air plant's leaves turn yellow.

I. Reasons for Yellowing Leaves on the Air Plant

1. The pot is too small

The air plant is a large herbaceous plant. If the pot is too small, its growth and development will be stunted, with little soil, few nutrients and little water, and then the plant's leaves will begin to turn yellow.

2. Low temperature

The air plant has relatively poor cold tolerance. If there is no heating in winter, the air plant will be frozen to death directly, so yellowing leaves are naturally quite normal.

In the south, where there is no heating, it should be taken outside during the day to get more sun and ensure a certain amount of light, so the plant grows sturdy and its ability to resist the cold is strengthened.

3. Root rot

Root rot is a relatively common problem for plants and directly affects the plant's appearance. After root rot, nutrients cannot be transported upward, and the leaves naturally turn yellow.

II. What to Do When the Air Plant's Leaves Turn Yellow

1. Cut off the yellow leaves

Since the leaves have already turned yellow, keeping them is of no use. You can unhesitatingly cut off the yellow leaves, and by the way you can give the air plant a trim to make it look better.

2. Repot

An air plant in a smaller pot has limited growing space and cannot happily grow green leaves and sprout small buds, so hurry and repot it into a larger pot, reconfigure the soil, and give the air plant enough growing space; only then can it grow better.

3. Keep it warm

After being frozen, the air plant will show the unhealthy condition of yellowing leaves. At this time, move it outdoors to get more sun, and at night you can place it in a warmer place indoors or in a plastic greenhouse.

4. Clear away the rotten roots

If the air plant has rotten roots, cut them off in time, and after the cuts heal, replant it.

The above is what Qinnong Network has compiled regarding the reasons for yellowing leaves on the air plant and the solutions. The air plant has relatively strong vitality. If the yellowing is really severe, you can select some leaves that are growing relatively well and propagate them again in relatively warm weather.
