A very common problem most gardeners face while growing Hibiscus plants is hibiscus leaves turning yellow. There are a couple of reasons behind why do Hibiscus leaves turn yellow. Let’s take a look at these reasons and also discuss solutions to these issues.
Why Are My Hibiscus Leaves Turning Yellow? Reasons and Solutions
If your Hibiscus leaves are turning yellow, you don’t need to panic. It does not mean your plant will die. It’s just a call for attention from your Hibiscus plant.
Here are some of the reasons why Hibiscus leaves turn yellow:
- Overwatering: Most gardening problems are usually caused by overwatering. Overwatering Hibiscus and not watering enough can both predispose your Hibiscus leaves turning yellow. Therefore, it is crucial to water your Hibiscus plant correctly. Make use of containers with good drainage holes for the proper flow of water from the drainage holes. You should also use a loose soil that allows easy water flow as the Hibiscus plant does not like too wet soil. You should also consider the climate you are living in. During the rainy season, you can move your plant container indoors.
- Temperatures: During the hot season, your Hibiscus plant may begin to stress out and turn yellow. You may need to water twice daily as your plant needs a lot of water during this period. Your plant may dry up and die from too much heat if you fail to water accordingly.
- Winter: Freezing weather can stress your plant and the leaves of your plants may turn yellow and fall off. Keep your plant indoors when it’s freezing.
You should also shield your Hibiscus plant from the wind. Your leaves can turn yellow when you move your plant indoors during winter. Your plant begins to go into dormancy during this period. This is why you should place your Hibiscus plant in the right place.
- Right placing: Placing your Hibiscus plant in the right place is very important. Especially when you decide to keep them indoors. Place them close to the window where they can get direct morning sunlight and good shade.
- Fertilizers: Lack of fertilization or over-fertilization can make your Hibiscus leaves turning yellow. If the plant is over-fertilized, the leaves turn yellow and fall off.
If the leaves of your plant turn partially yellow and don’t fall off, then it could be due to a lack of essential nutrients. Supply your Hibiscus plant with the right dosage of fertilizers.
- Pest attacks: The colorful blooming Hibiscus flower can attract beneficial pollinators as well as non-beneficial insects. Pest insect infestation such as spider mites, Hibiscus aphids, scale insects, etc, can attack your Hibiscus plant. They can cause injury to your plant and cause your leaves to turn yellow and drop off.
