As for the mimosa plant (Mimosa pudica), everyone has probably heard of it. Its flowers, leaves and seed pods all have good ornamental value, and its leaves in particular move at the slightest touch, making it very popular among plant lovers. Growing a mimosa at home is very easy, but being too careless can also cause problems, such as yellowing leaves. So what should you do when mimosa leaves turn yellow? Below are 5 causes of yellowing mimosa leaves and their solutions. Let's take a look together.
1. What to do when mimosa leaves turn yellow: find the cause
In our guide to growing mimosa, we mentioned that it has requirements for light, water and fertilizer, temperature and so on, and once these are not met, its leaves will turn yellow. So to deal with yellowing mimosa leaves, we need to find the cause first, and only then can we solve it in a targeted way. Below are 5 causes of yellowing mimosa leaves selected by the editor, along with solutions. Let's continue reading.
2. Causes of yellowing mimosa leaves and solutions
1. Environmental change
There are many reasons why mimosa leaves turn yellow, and plant lovers should first consider environmental issues. If your mimosa was just bought or just transplanted, it may not have adapted to a sudden, major change in its growing environment, which can lead to yellowing leaves.
Solution: Keep the growing environment of the mimosa unchanged; even if it must change, do it gradually so the plant has time to adapt. If the yellowing is caused by the environment, plant lovers can place the mimosa in a cool place to let it recover, and once the plant returns to normal, care for it in the usual way.
2. Too much or too little watering
Mimosa likes a moist environment, so it should be watered frequently, but both overwatering and underwatering can easily cause problems. Too much water makes the potting soil too wet, causing root rot and thus yellow leaves; too little water makes the potting soil too dry, and yellowing mimosa leaves will follow.
Solution: What to do when mimosa leaves turn yellow? If it is overwatering, you can move it to a sunny, well-ventilated spot so the water evaporates faster, or simply change the potting soil to freshen up the mimosa; if it is underwatering, increase the watering frequency and just keep the potting soil moist.
3. Insufficient light
During the growing process of mimosa, sufficient light is extremely important. Once light is insufficient, the mimosa leaves will turn yellow, which affects its ornamental value.
Solution: What to do when mimosa leaves turn yellow? If it is insufficient light, you can move the mimosa to a place with bright, indirect light to get some sun, but do not expose it to too much sun. In addition, to avoid the loss of nutrients, it is recommended to remove the yellow leaves.
4. Temperature too low
Mimosa likes a warm environment, and maintaining around 10°C in winter is enough for it to overwinter safely. Once the temperature is too low, it will affect the plant's growth and lead to yellow leaves.
Solution: Grow the mimosa in an environment of 20-28°C, and keep the room temperature above 10°C in winter.
5. Natural yellowing of leaves
As for the causes of yellowing mimosa leaves, if the above points are ruled out, then there is one more possibility: natural yellowing. It is said that if the two cotyledons of the mimosa turn yellow and wither naturally while the true leaves do not turn yellow, this is a normal phenomenon and you can leave it alone.

What to do when mimosa leaves turn yellow: yellow leaves not caused by transplanting
1. Temperature on the low side
If the yellowing is not caused by transplanting, then in winter you can place the pot on a windowsill indoors. Generally, an indoor temperature of around 10 degrees is enough for it to get through winter smoothly, so that growth is not affected by temperatures that are too low. It should be placed in a spot with plenty of sunlight, so the roots will grow relatively fast, and it needs frequent watering, preferably every day.
2. Temperature on the low side
In summer, if the weather is relatively hot and dry, you can water once each morning and evening, because lack of water may cause the leaves to turn yellow, and at this point the leaves will no longer close when touched. We need to apply additional fertilizer during the seedling stage, using fertilizer once every half month, but if you do not want the plant to grow too large, you can use a little less.
3. Light
Overall, the main way to deal with leaves that look yellow is to move it to a place with better indirect light to supplement the sunlight, without exposing it to too much sun. In addition, to avoid the loss of nutrients, it is recommended to remove the yellow leaves.
