A popular species for outdoor landscapes, patios and sun rooms alike, the hibiscus is a tropical plant known for its very large, brightly colored flowers. While most people learn to grow hibiscus successfully, it is a rather delicate plant that is more susceptible to certain environmental influences than other plant species. For this reason, it may require a bit more care than other plants in your landscape. 

If your hibiscus is green and producing blooms like crazy, it is healthy and happy. If your plant is turning yellow, however, it is experiencing some sort of distress. To get your plant on the road to recovery, you will first have to figure out what's causing the issue so you can correct it. Following are three reasons why your hibiscus might be turning yellow. 

Environmental Changes

Hibiscus plants are extremely susceptible to environmental changes. If the temperature in your area has dropped or risen suddenly, your plant may show temporary signs of distress, such as yellowed and/or dropped leaves. This may also occur if you move your plant to a spot that gets a different amount of sunlight, if you bring it inside, or if you place it in a different pot. Fortunately, yellowing caused by these temporary changes is often temporary as well. Your plant should return to normal once conditions stabilize.

Watering Inconsistencies

Your hibiscus requires a great deal of water, especially if it is in a pot. If it is rooted into your flower bed or yard, it will not dry out or become too soggy as easily, but it will still need to be watered if you notice that the soil is drying out. Water potted plants daily. If it is extremely hot or windy, you might have to water your plant twice a day. If you notice that the soil is not draining properly or is soggy, cease watering. Too much water can do as much harm as too little water. 

Fertilization Problems

Hibiscus plants do not like too much fertilizer, and they will yellow if you over-fertilize them. To properly feed your plant, choose plant food that's high in potassium and nitrogen but low in phosphorus. Feed your plant light, regular meals rather than heavy ones. 

There are many reasons why the leaves on your hibiscus might turn yellow and start to fall off. To help your plant recover, you must first find out what's ailing your plant. Once you do that, you can correct the problem and help your hibiscus along the road to a full recovery.
