Understanding African Violet’s Brown Condition
African violets are popular houseplants known for their beautiful and delicate flowers. However, sometimes their flowers may turn brown, indicating that the plant is not in good health. Brown flowers can be a sign of several issues, including overwatering, underwatering, nutrient deficiency, pests, and diseases.
When African violet plants are overwatered, the roots may become waterlogged, leading to root rot. Root rot can cause the leaves and flowers to turn brown and wilt. On the other hand, underwatering can cause the leaves to dry out and turn brown, which can spread to the flowers.
It is essential to water African violets properly by allowing the soil to dry out between watering sessions.
Nutrient deficiency can also cause African violet flowers to turn brown. These plants require specific nutrients, including nitrogen, phosphorus, and potassium, to grow and thrive. Lack of these nutrients can cause the flowers to turn brown and the leaves to become yellow.
It is essential to fertilize African violets regularly to ensure they have all the necessary nutrients.
Pests, such as spider mites and thrips, can also cause African violet flowers to turn brown. These pests feed on the plant’s sap, causing the flowers and leaves to dry out and turn brown. It is essential to inspect African violets regularly for signs of pests and take appropriate measures to control them.
Finally, diseases, such as crown rot and leaf spot, can cause African violet flowers to turn brown. Crown rot is caused by overwatering, and it can cause the crown of the plant to rot, leading to brown flowers and leaves. Leaf spot is caused by fungi and can cause brown spots on the leaves, which can spread to the flowers.
1. Watering and Soil Conditions
African violets are sensitive plants, and their soil and watering conditions are crucial for their health. Overwatering is one of the most common causes of African violet flowers turning brown. When the soil is too wet, the roots can’t absorb the water, leading to root rot and brown leaves and flowers.
To avoid overwatering, it’s important to wait until the soil is dry before watering again. You can check the soil’s moisture level by sticking your finger about an inch deep into the soil. If it feels dry, it’s time to water. If it’s still moist, wait a few more days before checking again.
It’s also important to avoid getting any water on the crown of your violet. Allowing too much water to build-up on the leaves may also lead to disease and brown spots forming. Watering from the bottom can help prevent this issue.
The type of potting mix you use can also affect your African violet’s soil moisture level. African violets prefer a fast-draining soil, so it’s important to use a potting mix that is specifically designed for these plants. If the soil is too dense, it can retain too much moisture, leading to brown leaves and flowers.
Poor drainage can also cause soil to become too wet, so make sure your pot has drainage holes. If you’re using a self-watering pot, be sure to monitor the water level to avoid overwatering.
2. Light and Temperature Requirements
African violets require a specific balance of light and temperature to thrive. Too much or too little of either can cause the plant’s flowers to turn brown. Here are some key things to keep in mind when it comes to light and temperature:
Light Conditions
African violets prefer bright, indirect light. Direct sunlight can scorch the leaves and cause brown spots to appear. On the other hand, too little light can cause the plant to become leggy and produce fewer flowers.
In their natural habitat, African violets grow under the canopy of trees, which filters out some of the sun’s rays. Mimicking this environment in your home can help your plant thrive. Placing your African violet near a north-facing window or providing it with filtered light can help it get the light it needs without being exposed to direct sunlight.
Grow Lights
If you don’t have a suitable window for your African violet, you can use a grow light to provide it with the light it needs. Grow lights are designed to mimic the spectrum of natural sunlight and can be adjusted to provide the right amount of light for your plant.
Temperature
African violets prefer temperatures between 65-75°F (18-24°C). Temperatures outside this range can cause the plant to produce fewer flowers or even stop blooming altogether.
Low temperatures can also cause the leaves to turn brown and become brittle. If your African violet is near an air vent or in a drafty area, it may be exposed to cooler temperatures than it can handle. Moving it to a warmer location can help it recover.
In summary, providing your African violet with the right balance of light and temperature is crucial for keeping its flowers from turning brown. Bright, indirect light and temperatures between 65-75°F (18-24°C) are ideal. If you need to supplement your plant’s light with a grow light, make sure to choose one that mimics the spectrum of natural sunlight.
3. Nutrition and Fertilizer Needs
African violets require specific nutrients to thrive, and proper fertilization is essential to ensure healthy growth and vibrant blooms. The recommended fertilizer ratio for African violets is 14-12-14, which provides the necessary balance of nitrogen, phosphorus, and potassium, along with trace minerals.
Over-fertilization, however, can lead to a buildup of fertilizer salts in the soil, which can damage the plant’s roots and cause brown spots on the leaves and flowers. It is crucial to avoid using too much fertilizer and to follow the manufacturer’s instructions carefully.
Potassium is an essential nutrient for African violets, as it strengthens the plant’s cell walls, making it less susceptible to disease and promoting better root growth. A lack of potassium can cause yellow and brown leaves. Therefore, it is essential to use a fertilizer that contains an adequate amount of potassium.
Water-soluble fertilizers are an excellent choice for African violets, as they are easily absorbed by the plant and provide a consistent supply of nutrients. Urea-free fertilizers are also a good option, as they are less likely to burn the plant’s roots and leaves.
Identifying and Treating Diseases
African violets are susceptible to various diseases that can cause their flowers to turn brown. Identifying and treating these diseases promptly is crucial to prevent further damage to the plant.
Common Diseases
1. Botrytis Blight
Botrytis blight, caused by the fungus Botrytis cinerea, is a common disease that affects African violets. It appears as small water-soaked lesions on the underside of the leaf, and leaves, stems, or flowers become blighted and turn dark brown to gray, often with a fuzzy coating on the surface.
Prevention and treatment include collecting and discarding all dead and dying plant material and using a fungicide.
2. Crown Rot
Crown rot is a severe disease that can cause the loss of entire groups of African violet plants. It is caused by fungi such as Pythium spp., Phytophthora spp., and Fusarium spp.

Here are some environmental factors that can cause African violet flowers to turn brown and what adjustments can be made to fix the issue.
1. Dry Air
African violets require high levels of humidity to grow properly. When the air is too dry, the flowers and leaves can start to wilt and turn brown. To combat this issue, it is recommended to place the plant in a humidity tray or mist the leaves regularly. Additionally, keeping a small fan nearby can help to circulate the air and prevent dryness.
2. Direct Sun Exposure
While African violets require bright, indirect light to grow, direct sun exposure can cause the flowers to turn brown. If the plant is placed in a window where it receives direct sunlight, it is recommended to move it to a location with filtered light.
3. Environmental Conditions
Unfavorable environmental conditions such as low temperatures, poor soil aeration, wet soil, or excessively dry air can contribute to flower failure. Maintaining a consistent temperature between 65-75°F and using a well-draining soil mix can help prevent these issues.
4. Air Circulation
African violets require good air circulation to prevent the growth of fungi, which can also turn leaves brown. If the plant is in a stagnant area, it is recommended to move it to an area with better air circulation. Keeping the doors and windows in the house open can also help to improve air circulation.
5. Roots
Overwatering or underwatering the plant can cause root damage, which can lead to brown flowers. It is recommended to water the plant when the top inch of soil is dry and to avoid getting water on the leaves. Additionally, repotting the plant every 6-12 months can help to ensure healthy root growth.
Proper Care for New and Old Growth
To keep African violets healthy and vibrant, it’s essential to provide them with proper care. This includes paying attention to both new growth and the oldest leaves on the plant.
New growth should be encouraged by providing adequate light and water. African violets prefer bright, indirect light, so placing them near a sunny window with a sheer curtain is ideal.
Watering should be done when the top inch of soil feels dry to the touch. Overwatering can lead to drooping leaves, limp foliage, and flower loss, while underwatering can cause wilting and drooping leaves.
As for the oldest leaves, it’s natural for them to turn brown and eventually detach from the plant. This is a sign of natural aging and should not be a cause for concern. However, if the leaves are turning brown prematurely, it could be a sign of a problem with watering or light.
To ensure that African violets continue to produce blooms, it’s important to fertilize them regularly. Use a balanced fertilizer, such as a 10-10-10 formula, and apply it every two weeks during the growing season. Be sure to follow the instructions on the package carefully to avoid over-fertilizing, which can damage the plant.
Repotting and Soil Issues
African violets need to be repotted every 6-12 months to ensure they have enough room to grow and access to fresh soil. Signs that an African violet needs to be repotted include a root-bound plant, slow growth, and lack of blooms. Repotting an African violet while it is in bloom is possible, but it can shock the plant and cause it to drop its flowers.
When repotting an African violet, it is important to use a well-draining potting mix that is specifically formulated for African violets. A mix that is too dense can cause the soil to retain too much moisture, which can lead to root rot. On the other hand, a mix that is too light can dry out too quickly and cause the plant to wilt.
Another common soil issue with African violets is salt buildup. This can happen when tap water is used to water the plant, as the minerals in the water can accumulate in the soil over time. Signs of salt buildup include brown tips on the leaves and a white crust on the soil surface.
To prevent salt buildup, it is recommended to use distilled or rainwater to water African violets. If tap water must be used, it is important to flush the soil periodically to remove any excess salt. This can be done by watering the plant thoroughly until water runs out of the drainage holes in the bottom of the pot.
