Causes of Yellowing Leaves in Potted Plants and How to Fix Them

Many of you probably know that yellowing leaves on potted plants not only ruin their appearance but also affect the plant's lifespan. So, what causes potted plant leaves to turn yellow? And how do you fix it?

First of all, leaf yellowing is the most common problem we encounter when growing flowers. A perfectly healthy plant suddenly, for no apparent reason, develops a few leaves that slowly turn yellow, wither and drop off, which is heartbreaking to see. The causes of yellowing leaves in potted plants are as follows:

1. Water-induced yellowing. Too much water in the potting soil, or waterlogging, can cause the plant's root system to become diseased and rot. The symptoms are new tender leaves turning dark and lusterless, and new shoots withering.

Solution: Reduce watering, loosen the soil promptly so the moisture evaporates as quickly as possible.

2. Drought-induced yellowing. The opposite of water-induced yellowing, this refers to yellowing leaves caused by a lack of water resulting from improper watering over a long period. For example, repeatedly giving only a "half watering", or the pot being overfilled with soil so water cannot soak through, shows as new leaves keeping a normal color while old leaves slowly dry, turn yellow and drop starting from the base.

Solution: Remove the excess potting soil, water thoroughly, or use the soaking method to let the potting soil absorb water fully.

3. Fertilizer-induced yellowing. Over-fertilizing makes new leaves thick and stiff rather than opening out, while old leaves turn yellow and drop off.

Solution: Stop fertilizing and water frequently, or sow some leafy vegetable seeds in the pot, let them sprout and grow to a certain height, then pull them out, so they use up the excess fertilizer.

4. Nutrient-deficiency yellowing. Yellowing leaves caused by not repotting or changing the soil for a long time, not fertilizing enough, or the pot being too small.

Solution: Apply fertilizer and water promptly according to the plant's growth needs, repot and change the soil once every one to two years, and apply plenty of base fertilizer when repotting.

The above is an introduction to what causes yellowing leaves in potted plants and how to solve it. We hope it is helpful to you.
