Plant Leaves Turning Yellow With Brown Spots

The most typical reason for plant leaves to turn yellow and develop brown spots is leaf spot disease. This is caused by a fungus that attack the plant’s leaves. If you think your plants have been affected by this disease, the first thing you should do is ensure that they are kept away from your healthy ones while being treated. Remove any sickly leaves and dispose of them properly to prevent spores from spreading to the rest of your garden’s plants. Looking to try something new? Check out this.

Baking soda and water solution may be used to treat leaf spot disease on plants. Spray the diseased leaves with it.

Why are my plant’s leaves turning yellow with brown spots?

Leaf spot disease is the most likely answer. Brown spots with yellow margins on your plant might be a symptom of this fungus infection. It can harm both your indoor and outdoor plants. If spores from nearby diseased leaves fall onto one of your plants, they may enter through its roots and infect it, causing the distinctive fungal leaf spot to develop if the spores begin to reproduce. When the fungus goes unnoticed in the plant for an extended period of time, it grows larger. These spots begin to touch one another and appear browner rather than smaller. The leaf will eventually be totally blackened and fall off the plant into the dirt. This is when the spores will wait for future plants to infect.

Reasons That Could Explain Why Your Plant Leaves Are Turning Yellow:

The Plant is Still Getting Acclimated

If you’ve ever moved, you know how difficult it can be to get all situated in and the new location to truly feel like home. Plants are no different. “If you just bought the plant, its leaves might be yellow because it is adjusting to its condition,” LeStrange explains. “First make sure there is enough light for the plant before anything else. Also, try misting the plant with a mister and applying a weak micronutrient solution to help rejuvenate and relieve stress to the plant.”

The Plant is Sensitive To The Water

Tap water might also be the cause of your foliage dying. “Indoor foliage plants can have a sensitivity to the chemicals and minerals such as fluoride, salts, and chlorine that may be present in tap water,” explains Mast. “Fill a pitcher or container with water and leave it uncovered overnight so that the minerals evaporate. Rainwater or distilled water are other options.”

The Plant is Getting Too Much Light

Plants that want low to medium light may get scorched if they receive too much sunshine, according to some experts. A quick Google search will tell you what kind of lighting is ideal for your plant. Otherwise, Mast advises moving the plant to various parts of your home where it can obtain medium to bright indirect light and seeing where it thrives best.


To be safe, you should use the following guidelines:. Too much water is just as bad as too little. Soil that doesn’t drain properly will suffocate the roots. The roots will die if there isn’t enough oxygen, and the leaves will yellow and fall off. Water only when the earth in your container starts to dry out; then wait for it to dry completely before watering again. Make sure your container has adequate drainage holes and water it less often. When repotting an overwatered plant, examine its roots. Black roots indicate decomposition and a foregone conclusion of death if not treated, while white roots indicate a healthy plant. Trim all of the black areas off your repotted plant’s root ball leaving just healthy white roots to recover if it has black roots. This is algae, and it may also be seen on the soil’s surface as a green slimy look If there is an algal growth on the earth, this is indication that you have overfertilized.


When plants do not have enough water, they will drop their leaves to avoid dying. It’s frequently the case that the method your plant is watered is the problem. Water your plants less often but make sure they are fully wet to stimulate the roots to grow deep in the soil. Make sure you’re watering your plants correctly: wait until the ground begins to dry before watering it fully, then wait until it starts drying out again before watering it again.


Leaf spot disease is most likely the cause if your plant’s leaves become yellow and have brown spots on them. A fungus causes this illness, leaving behind brown spots as a result of feeding on the leaf. Spray the plant with a combination of baking soda, mineral oil, and water to destroy the fungus. To be sure that all fungus and spores are destroyed, apply the solution once each week for a month. Also make sure you keep infected plants away from healthy ones.
