What Causes Yellow Leaves?
Yellow leaves (chlorosis) usually mean your plant is stressed. The most common reasons are:
- 💧 Overwatering
- 🏜️ Underwatering
- ☀️ Low light
- 🌱 Nutrient deficiency
- 🪴 Root problems
- 🍂 Natural aging
Let's go through each cause and how to fix it.
1) Overwatering 💧
Overwatering is the #1 cause of yellow leaves. When roots sit in soggy soil, they can't absorb nutrients or oxygen → leaves turn yellow + soft.
Signs:
- • Wet, mushy soil
- • Yellowing bottom leaves
- • Drooping even when soil is moist
Easy Fix:
- ✓ Let soil dry before watering
- ✓ Check moisture with your finger before watering
- ✓ Improve drainage with well-draining soil & drainage holes
2) Underwatering 🏜️
When plants don't get enough water, leaves turn yellow, dry, or crispy.
Signs:
- • Dry soil pulling away from pot
- • Crispy leaf edges
- • Drooping
Easy Fix:
- ✓ Water slowly until soil is fully moist
- ✓ Create a consistent watering schedule
- ✓ For very dry soil, soak the pot in water for 10–15 minutes
3) Not Enough Light ☀️
Plants need light to make energy. Low light → pale, yellowing leaves + slow growth.
Signs:
- • Pale or thin leaves
- • Leaning toward window
Easy Fix:
- ✓ Move plant to a brighter spot (bright, indirect light)
- ✓ Clean dusty leaves so they can absorb more light
- ✓ Consider a grow light in winter
4) Nutrient Deficiency 🌱
When soil lacks nutrients—especially nitrogen—older leaves turn yellow first.
Signs:
- • Older leaves yellow; new leaves look normal
- • Slow growth
Easy Fix:
- ✓ Fertilize monthly in spring + summer
- ✓ Use a balanced liquid fertilizer
- ✓ Don't fertilize in winter—plant growth is slower
5) Natural Leaf Aging 🍂
Yellowing isn't always bad! Older leaves naturally yellow + fall off.
Signs:
- • Only 1–2 older leaves affected
- • Newer leaves look healthy
Easy Fix:
- ✓ Remove old leaves as needed—totally normal
