If you are here, you already know how to grow gardenia plants but lack the knowledge to take care of them. So we went straight to the point and discussed why you noticed some Yellow Leaves On your Gardenia Plant.

I will try to cover every possible cause that can make your gardenia plant’s leaves turn yellow. Some of these points are based on personal experience, while others are the result of research. My goal is to ensure that when you visit this page, no question is left unanswered.

Causes Of Yellow Leaves On Gardenia:

1. Improper Watering

This is one of the most common problems we gardeners face. Either we overwater, which causes root rot, or underwater our plant, which stresses the plant and leads to yellow leaves.

Solution: Gardenia needs one inch of water per week (approximately o.68 gallons per square foot). Keep soil moist, but avoid making it soggy.

2. Light Issues

The sun is the source of energy for our Earth and all the living beings on our blue planet. However, we need this energy in a balanced way.

Too much or too little sunlight isn’t good for us or for our plants. Gardenia needs bright indirect sunlight. Excessive sunlight can scorch leaves while too little can cause yellow leaves.

3. Weather

Weather is one of the key things you have to know when you grow any plants in your garden and home. Gardenia like warm temperatures (60–75°F) and high humidity. Sudden changes in temperature cause yellow leaves on gardenia.

4. Soil ph

I am not one of those gardeners who checks soil pH levels before planting. However, some plants, like gardenia require perfect soil pH levels to grow healthy and thrive.

Gardenias thrive in acidic soil (pH 5.0–6.5). Check the pH level using pH test strips.

5. Nutrients Deficiency

• Iron deficiency in gardenia is one of the most common causes of turning leaves yellow with dark green vines.
• Nitrogen deficiency generally yellowing older leaves, often due to poor soil quality.

Prevention Tips:

• Maintain soil acidic level (pH 5.0–6.5).
• Apply the fertilizer which is specially designed for acidic acid-loving plants.
• You can also use organic compost to improve soil nutrient levels.
• Test your soil regularly to maintain pH and nutrient levels.

6. Pests

The most common enemies of not just gardenia but the whole garden, whether it’s indoor or outdoor. These little monsters-like spider mites, aphids, and whiteflies can weaken plant growth and are one of the leading causes of yellow leaves.
