We know that your indoor plants are more than just decorative elements—they’re a part of your living space. So, when your green companions start showing signs of stress like yellow leaves, it’s natural to worry. Many plant parents ask us, “Why are my plant leaves turning yellow?” The answer can vary, but it’s usually your plant’s way of signaling that something’s off.
If you’ve spotted leaves turning yellow, curling, or drying up, don’t panic. Below, we’ve compiled the top 5 reasons behind why plant leaves turn yellow, and what you can do to bring back the greenery.
1. Underwatering – Yellow, Drooping, and Curling Leaves
If your plant’s leaves are yellow and dry, curling inward, and the soil feels bone dry or pulls away from the edges of the pot, it’s likely thirsty. Underwatering causes the plant to shed older leaves to conserve energy.
Give your plant a thorough drink until water runs out from the drainage holes of your HOCC ceramic planter. Make sure the water is evenly absorbed. If it’s pooling at the top or draining too quickly, your soil may be compacted. Use a wooden stick or skewer to gently aerate the soil. Your plant will often bounce back within hours to days.
2. Overwatering – Bright Yellow Leaves and Mushy Stems
One of the most common reasons why plant leaves turn yellow is overwatering. If your soil is constantly soggy and your plant has bright yellow leaves or soft, dark stems, you might be watering too frequently—or your plant isn’t getting enough light.
Let the soil dry out between waterings. Ensure your planter has good drainage. If your plant is sitting in a low-light corner, consider moving it to a brighter spot. Overwatering combined with low light is a major trigger for yellow leaf disease and even root rot. If needed, repot your plant in fresh, dry soil.
3. Irregular Yellow Spots or Deformed Leaves – Pests or Disease
Noticing strange yellow patches or leaf deformation? This could be caused by pests like spider mites or fungal infections that thrive in humid, poorly ventilated environments.
What you can do is, check your plant thoroughly for pests. If none are found, it’s likely a bacterial or fungal yellow leaf disease. Prune away infected leaves and improve air circulation around your plant. Keep foliage dry and consider using a safe fungicide. Placing your plant in a well-designed HOCC ceramic planter can also help regulate humidity levels around it.
4. Whole Plant Yellowing – Nutrient Deficiency or Pot-Bound Roots
When yellow leaves on plants appear throughout the entire plant, or you notice a general dullness in color, it may signal a lack of nutrients like nitrogen or iron—or your plant might be pot-bound with roots circling the inside of the pot.
Either repot your plant into a larger HOCC ceramic planter with fresh, nutrient-rich soil or feed it with a balanced houseplant fertilizer. If your plant still has growing space in its current pot, nutrient supplementation might be all it needs.
Temperature fluctuations, like drafts from ACs or heaters, can also cause the leaves to yellow and dry. Ensure your plant isn’t sitting too close to an open window or heat source.
5. Only Mature Leaves Turning Yellow
Sometimes, leaves turning yellow isn’t a cause for alarm. Plants naturally shed older leaves as they grow. If only the bottom or mature leaves are yellowing and the rest of the plant looks healthy, it’s probably just doing its thing.
No action is needed! Gently remove the yellowing leaves if they bother you aesthetically. Your plant is simply focusing energy on new growth.
