The Most Common Mistake
Overwatering is the number one cause of plant problems for new gardeners. More plants die from overwatering than underwatering. Learning the signs can save your garden.
Yellowing Lower Leaves
When plants get too much water, the oldest leaves often turn yellow and droop. Waterlogged soil prevents roots from absorbing oxygen. If you see yellow lower leaves with wet soil, overwatering is likely.
Wilting Despite Wet Soil
This is the most confusing symptom — a plant that looks thirsty when soil is wet. Damaged roots cannot take up water. Always check soil before watering. If wet and wilting, let it dry out.
Mold on Soil Surface
Green algae or white fuzzy mold on soil is a clear sign of excess moisture. Scrape it off, improve airflow, and let soil dry more between waterings.
Stunted Growth
Constantly overwatered plants grow slowly with pale or yellow leaves. Often mistaken for nutrient deficiency, but the real problem is root suffocation.
How to Fix It
Stop watering immediately and let soil dry. Check drainage holes. Move containers to a sunnier spot. Improve garden bed drainage with compost. Always check soil moisture before watering going forward.
