Why are my indoor plant leaves turning yellow and falling off?

Introduction

Yellowing leaves are a common cry for help from indoor plants. The cause can range from watering mistakes to lighting, nutrition, or simply the plant’s natural aging. Knowing the pattern — which leaves yellow first, and how they fall — will tell you exactly what’s wrong.

1) Overwatering and root rot

If the soil stays soggy and leaves turn yellow starting from the bottom, overwatering is the top suspect. Roots lose oxygen, leading to soft stems and eventually leaf drop.

2) Light imbalance

Too little light causes slow growth and pale, limp leaves. Too much direct sun, on the other hand, can bleach or burn foliage. You’ll notice crispy edges or yellow patches on the sunniest side of the plant.

3) Nutrient or aging issues

Lack of nitrogen, magnesium, or iron can make leaves fade or yellow between the veins. But if only the oldest leaves drop while new growth looks healthy, it might just be the plant’s normal aging cycle.

4) Check your watering and drainage setup

Always water deeply but let the top 2–3 cm of soil dry before watering again. Make sure your pot has drainage holes and avoid letting it sit in excess water.

5) Environmental stress

Cold drafts, dry air, or sudden location changes can shock indoor plants, causing rapid leaf yellowing and drop. Try to keep temperature and humidity consistent.

Conclusion

Yellow leaves aren’t always a death sentence — they’re your plant’s feedback. Observe patterns, adjust care habits, and your plant will soon return to lush, green growth.
