Houseplant leaves turning yellow: You might face that your houseplant leaves turn yellow, and you are seeking the reason for that. When plant leaves turn yellow, this shows a problem keeping your houseplant; for instance, improper watering, nutrient deficiency in a warm and dry environment, etc. You need to examine all the problems mentioned above. In the following, we will discuss these problems and how to overcome them.
Houseplant leaves turn yellow as a result of improper watering
If your plant is dry (leaves are entirely yellow and have wilted), you can help it through watering. One simple and effective way is bottom watering. You need to Fill a container with water and put your flower in it; this way, the roots will be fully watered, and there will be no more yellow leaves. Low watering causes the organelle to lose water; consequently, leaves turn yellow and wilted.
Overwatering and houseplants leave yellow
Sometimes the problem results from overwatering (leaves gradually get yellow and stems become black). Most of the time, houseplant leaves turn yellow due to this problem. To avoid such problems, you should control the amount of water and let the soil get dry. Touch the soil with your finger, and if you feel it is dry, you can water it.
A common problem that might happen due to overwatering is the appearance of worms in the pot’s soil. In these cases, you must get rid of the worms and change the soil. If you keep the soil dry, worms will be eliminated, and if you want to change the soil, you need to gently wash the roots and immediately put them in the new soil.
Overwatering will decrease the air around the root, and it causes root rot. Besides that, in most cases, it causes blisters on the stem of the plant, called edema. Too much water around the root can give rise to a fungal disease that is dangerous for your plant. The good news is that you can prevent all these problems by controlling the watering.
Underwatering and Its Effects on Houseplants
Underwatering is a common issue that can have detrimental effects on the health of houseplants. When plants do not receive an adequate amount of water, they struggle to perform essential functions like nutrient absorption and photosynthesis. As a result, the leaves may start to turn yellow as the plant prioritizes preserving water by reducing metabolic activities. The lack of water availability hinders the transportation of nutrients within the plant, leading to cellular damage and discoloration of the leaves. In addition to yellowing, underwatered plants often exhibit wilting and dryness, signaling their distress.
Identifying the signs of underwatering is crucial for prompt intervention. Common indicators include visibly dry and brittle soil, wilting leaves, and, notably, yellowing leaves starting from the lower portions of the plant. To address underwatering, it’s essential to adjust the watering frequency and ensure that the soil is consistently moist but not waterlogged. Deep watering, allowing water to penetrate the entire root system, is beneficial in restoring the plant’s hydration. Regularly monitoring soil moisture levels and adjusting watering practices accordingly is key to preventing and alleviating the impact of underwatering on houseplants.
nutrient deficiency in the soil
If the leaves of the upper parts of the plant gradually turn yellow, or the process of leaves turning yellow is not normal, its highly that the problem is with the plant’s nutrition; for example, if you haven’t fertilized your plant for a long time, giving some will reduce the yellowing process. On the other hand, the high amount of calcium in the water can lead to houseplant yellow leaves. You should know that old leaves turning yellow is a natural process; however, if this process is very high and fast, it can be due to nitrogen deficiency. Houseplant leaves turning yellow due to iron deficiency appear as yellow streaks on the younger leaves. Among other elements that their deficiency will lead to houseplant leaves turning yellow are phosphorus and potassium. In potassium deficiency, yellowing will start from around the leaf and go inside it. If you use water with a lot of salt, the plant will get poisoned, i.e., excessive intake of nutrients.
Dry weather and houseplant yellow leaves
relative humidity, i.e., The amount of humidity in the environment of your house is crucial for your plants. During the warm seasons of the year, when the warm weather leads to low humidity to provide the needed humidity, you can use a cold mist humidifier or use a container of water next to the flower pot. Also, you can spray water from time to time. Do not spray too much, only to the extent that the plant’s humidity is maintained. However, not all plants need spraying, and even it may cause leaf spots. Get familiar with your plants and their needs; never spray during noon. Another simple way to provide the needed humidity is by creating an island. Dry weather will increase evaporation, harming the plant’s internal organelle. Moving the plant to a new place and adjusting the temperature and humidity, your plant will grow new leaves.
Cold winds and houseplant yellow leaves
another factor that causes yellowing in plants is cold wind in the environment. If tropical plants are exposed to cold wind, their leaves will turn yellow. Also, if the plant is exposed to air coolers, it will face some issues. Therefore, if your plant is exposed to cold winds, it’s better to move them to a new place that is warmer. When the plant is in a suitable environment, it will return to its previous state.
Light shortage and houseplant leaves turning yellow
You have a light problem if your plants’ leaves have big yellow spots or the stem is getting yellow. Move it to a place that has good and filtered light. Note that you should never expose the plant to direct sunlight. In case of light shortage, the chlorophyll of the leaves, which is responsible for the which cause the color of your plant, loses its efficiency. Therefore the plant will lose its freshness and greenness. So don’t forget to control the light.
Diseases that cause houseplant yellow leaves
Plants are prone to viral, bacterial, fungal, and nematode (Roundworms) Diseases. All of them can cause houseplant leaves turn yellow. Nematoda is a small worm-like creature that lives inside the soil. When these nematodes feed on the roots, they cause houseplant leaves to turn yellow and other symptoms in the plant. Check the roots, and nematodes infect the roots if you see any unusual gall or knot on them.
Viral infections cause houseplant leaves turn yellow
Viral agents, like other plant contaminating agents, can cause yellowing in the plant. These agents can cause symptoms and yellow spots on the plant. Leaves turning yellow might be accompanied by other signs like deformed leaves or roots and sometimes pale flowers. Unfortunately, no definitive treatment has been found for such plant diseases. The best thing you can do is to separate the infected plant from others to prevent transmission. Viral diseases can be easily transmitted through touching. Isolating the infected plant is the best way to save others. Note that viral diseases and symptoms start from the plant’s upper leaves and spread throughout the whole plant.
Blights and insects and houseplant leaves turning yellow
Insects feeding on the plant can sometimes lead to leaves turning yellow; for example, aphids can cause this issue.
For example, if you see many webs on the leaves, the spider mite has chosen your plant as its host.
Interestingly, these insects feeding from your plant can carry viral and bacterial agents that might infect the plant. So, it would be best if you prevented them by pruning the infected leaves and stems and spraying them with proper pesticides. Too much pesticide can cause the plant to dry up. So, pay attention to the dosage written on each bottle and dilute it to the right amount. Blights that usually attack your plant are as follows: whiteflies, thrips, aphids, and ticks; you can get rid of them using a particular pesticide.
Other reasons for houseplant leaves turning yellow
Aging can cause houseplant leaves yellow and drop. It’s pretty common in plants like Dieffenbachia. So, no need to worry.
Remember, when you move the plant to a new place or report it, it might face stress, and for a period of time, it might get wilted and turns yellow. It’s normal, and after moving the plant to its proper place, it will return to its previous state.
The soil’s acidity level can also cause yellow leaves and brown spots on the leaves.
What steps can I take to revive a houseplant with yellow leaves?
Reviving a houseplant with yellow leaves requires a combination of attentive care and targeted adjustments to its environment. First and foremost, assess the watering routine. Ensure that you are neither overwatering nor underwatering the plant by checking the soil moisture regularly. If the soil feels dry, provide a thorough watering, allowing water to reach the entire root system. Conversely, if the soil is waterlogged, allow it to dry out before the next watering. Trimming away severely yellowed or dead leaves is beneficial in redirecting the plant’s energy towards healthier growth.
Simultaneously, evaluate the lighting conditions. Ensure your houseplant is receiving the appropriate amount and type of light for its species. If it’s receiving too much direct sunlight, consider moving it to a spot with filtered or indirect light. Conversely, if it’s in a low-light area, relocate it to a spot with brighter, but still suitable, light conditions. Additionally, inspect the plant for signs of pests or diseases, addressing any issues promptly. Finally, consider adjusting the fertilizer regimen, ensuring it aligns with the specific needs of your houseplant. With these steps, you can give your yellowing houseplant a chance to recover and thrive once again.
How do you prevent houseplant leaves from turning yellow?
