Why my Begonia leaves turning yellow?
If your Begonias turning their colors to brown, it might be one of the reasons below and if you take care of these problems and solve them your plant will come back to life.

Watering
Incorrect watering is one of the main reasons why your Begonias are dying.
If you are keeping your begonias indoors you should water them once a week but if you keeping them outside, you should water them when the first inch of the soil is dry.
If you overwater them, the roots of the plant will start to rot very quickly and eventually will kill your plant.
Also if you underwater them the roots will dry out and the plant will also die. Make sure Begonias that planted outdoors gardens or pots that are well drained.
If you don’t know when to water your plants you can use water meter, this device measures the water around plant which is a helpful tool to let you know when the Begonias should be watered.
Note that tuberous plants require watering more often than Begonias in order to maintain their massive size blooms.
However, you should be very careful to not to water them before they want it otherwise they will die from root rot.
-
Sunlight
Flowering Begonias need couple of hours of sunlight and the rest of the day, they want t be in a bright spot but not under direct sunlight.
Too much sunlight will dry out the plant very quickly and stops the growth of the plant, also not enough sunlight will slow the growth and to develop fungi.
If you are growing your begonias indoors and if they are between flowering stage, you shall not allow them to be under direct sunlight but rather in a room that has diffused sunlight, a bright room, al the time.
Begonia plants that are grown to their foliage do not require direct sunlight at all.
-
Soil
It is very important to plant Begonias in a soil that is rich in nutrients and also has low PH levels, you can find it in mixture of heavy soil, peat moss, Manure AKA three-mix potting soil.
Outdoor Begonia`s soil which are planted in gardens, need to be refreshed every year with a new layer of soil mix and then mix into the garden.
Also indoor plants should have the first couple of inches of soil removed and replaced every six months.
-
Fertilization
You need to fertilize your Begonias regularly to keep the plant healthy, the foliage green and the blooms big and colorful.
It is not recommended to use chemical fertilizers that are high in salt which it can damage your plant`s roots.
A good fertilizer has good amount of nitrogen, phosphorous and potassium and that is water-soluble for flowering plants.

what to do if my begonia leaves turning yellow?
- Adjust watering: Make sure you’re giving your begonias the proper amount of water. Browning of flowers can result from either overwatering or underwatering. Before rewatering, let the top inch of soil gradually dry out. To check the soil’s moisture content, stick your finger into it.
- Provide cover; although sensitive to direct sunshine, begonias like bright, indirect light. Consider shifting your begonias to partial shade if they are in direct sunshine, or give them some shade during the hottest part of the day if they are.
- Pruning the damaged areas: If you observe browning blooms or foliage, remove it right away to stop the spread of any fungus or disease. Additionally, this will help direct the vitality of the plant into healthier areas.
- Increase airflow: Preventing bacterial or fungal infections that can cause flower browning requires good air movement. Be careful not to overcrowd your begonias, and make sure there is enough room between them for optimal ventilation.
- A moderate humidity environment is ideal for begonia growth. Use a humidifier or put a tray of water nearby the plants to improve humidity if the air is excessively dry, especially in the winter or in heated indoor situations.
- Apply fungicide: You might think about using a suitable fungicide or bactericide if fungal or bacterial infections are still present and causing flower browning. Apply as instructed and pay close attention to the directions.
- Use a balanced fertilizer made specifically for flowering plants to offer the essential nutrients. Avoid overfertilizing, too, since this can cause salt to build up and put further stress on the plants. Observe the dosage and schedule suggested on the container for the fertilizer.

See us again.
I’ve noticed that the leaves of my begonias are turning yellow. Any idea what might be causing it?
Hi Grace123, yellowing leaves in begonias can be a result of various factors such as overwatering, underwatering, nutrient deficiencies, or even pests. It’s essential to examine the watering routine, ensure proper drainage, and consider fertilizing with a balanced fertilizer. You might also want to inspect the leaves for signs of pests. Hope this helps!
My begonia leaves are turning brown around the edges. What could be the reason?
Hi GreenThumb92, brown edges on begonia leaves can indicate issues like underwatering or inconsistent watering, low humidity, or exposure to direct sunlight. Check your watering habits and adjust accordingly. Consider providing some humidity by misting the leaves or placing a tray of water nearby. Also, make sure your begonias are not in direct sunlight for prolonged periods.
I’ve recently repotted my begonia, and now the leaves are turning yellow. Did I damage the roots?
Hi PlantLover23, repotting can sometimes cause temporary stress to plants, including begonias. Yellowing leaves after repotting can be a sign of transplant shock. Ensure you used well-draining soil and didn’t damage the roots during the process. Give your begonia some time to adjust to its new environment, and continue to provide proper care. The leaves should recover in due course.
I suspect my begonia has a nutrient deficiency since the leaves are turning yellow. Which nutrients should I focus on?
Hi BlossomGarden, yellowing leaves can indeed be a sign of nutrient deficiency. In the case of begonias, pay attention to the levels of nitrogen, iron, and magnesium. Consider using a balanced fertilizer specifically formulated for begonias to address any deficiencies. Follow the instructions on the fertilizer package for the appropriate dosage and application frequency.
My begonia leaves are turning yellow and falling off. Is my plant dying?
Hi LeafyWonder, it’s natural for begonias to shed older leaves over time. However, excessive leaf yellowing and leaf drop could indicate underlying issues. Review your watering practices, light exposure, and check for pests or diseases. With proper care, your begonia should continue to thrive and produce new foliage.
I water my begonia regularly, but the leaves are still turning yellow. What am I doing wrong?
Hi SunshineGardener, while regular watering is important, the key is to water correctly. Ensure the soil is well-drained and doesn’t stay excessively wet. Allow the top inch of soil to dry out before watering again. Overwatering can lead to root rot and yellowing leaves. Double-check your watering routine and adjust as necessary.
I noticed small bugs on my begonia leaves, and they are turning yellow and brown. How do I get rid of them?
Hi PetalEnthusiast, the small bugs you mentioned could be pests like aphids, mealybugs, or spider mites, which can cause damage to the leaves. Start by gently washing the leaves with a mild soapy solution or using a neem oil solution to control the pests. Ensure you treat both the upper and lower leaf surfaces. If the infestation persists, you may need to resort to a targeted insecticide specifically designed for the type of pests you’re dealing with. Be sure to follow the instructions on the product carefully.
I’ve noticed that my begonia leaves are turning brown and crispy. Could it be due to excessive heat?
Hi BotanicalDreams, yes, excessive heat can cause begonia leaves to turn brown and become crispy. Begonias prefer moderate temperatures and can suffer from heat stress if exposed to intense sunlight or high temperatures for extended periods. Consider moving your begonias to a cooler and partially shaded location to help alleviate the issue.
I’ve been watering my begonias regularly, but the leaves are still turning yellow. Could it be a sign of overwatering?
Hi GreenLeaves4Life, surprisingly, both overwatering and underwatering can cause yellowing leaves in begonias. While regular watering is important, it’s crucial to ensure the soil has proper drainage. If the soil remains consistently soggy or waterlogged, it can lead to root rot and yellowing leaves. Check the soil moisture levels and adjust your watering frequency accordingly.
My begonia leaves are turning yellow and translucent. What could be the reason, and is there any hope for recovery?
Hi FlowerPower87, yellow and translucent leaves in begonias often indicate overwatering or poor drainage. The excess moisture can cause the leaves to become mushy and transparent. To help your begonia recover, ensure the soil has proper drainage, and adjust your watering habits accordingly. Trim away any severely affected leaves and provide appropriate care. With time, your begonia should show signs of improvement.
