Tropical hibiscus plants can be one of the most dramatic and beautiful flowers to include in your garden. They can, however, be sensitive to environmental changes, which could leave you with yellowing leaves. While a few yellow leaves are no cause for concern, if you notice a large number growing yellow, it’s time to do a little investigating to determine and correct the problem.

5 Reasons Your Hibiscus Is Yellowing

1. Lack of Sunlight

Hibiscus flowers love sunlight and will yellow and die without enough of it. If the leaves have yellow or white spots, rather than an overall yellowing, it could be getting scorched by the sun, especially if the plant spends a lot of time in direct, late afternoon sunlight.

2. Wrong Temperatures

The ideal temperature for a hibiscus is 60 to 80 degrees Fahrenheit. Extreme cold or heat could be causing the problem. If your plant is indoors, check for leaky windows or vents nearby that could be exposing the plant to radical temperature changes throughout the day.

3. Too Much Fertilizer

Fertilizer can be great for a hibiscus, but too much fertilizer could be the reason your plant is yellowing. If you fertilize frequently, try cutting back to see if this solves the problem.

4. Poor Soilhibiscus

There are a few soil issues that could be the root of the problem, including poor drainage, which causes wet conditions, or not enough soil. These are easily solved by repotting or changing the plant’s location if it’s in a garden. Also, check the pH of the soil. A hibiscus grows best in a somewhat acidic soil.

5. Poor Watering

Too much or too little water is the most common reason for a hibiscus plant to have yellowing leaves. The plant thrives with lots of water, but yellows under wet conditions. Make sure the plant’s roots aren’t sitting in water.

The beautiful hibiscus plant requires patience and attention, but is worth the effort. Once you find the right environment for the plant, it will reward you with beautiful, vibrant blooms.
