Yellowing and drying cucumber leaves are every gardener’s nightmare. They often appear unexpectedly – even with regular watering, the leaves begin to pale, curl, and gradually die off from the edges. This problem can have a number of causes: from nutrient deficiencies to fungal infections or stress from heat and sun. The good news is that there is a simple, cheap, and natural way to protect plants and restore their vitality.
Most common reasons cucumber leaves turn yellow
Before you start fixing it, it’s good to know why the leaves are being damaged in the first place. The most common causes include:
- Lack of nitrogen or magnesium, which are necessary for chlorophyll production.
- Excessive sun, especially at midday. Sunburned leaves turn yellow and dry out.
- Improper watering – either overwatering or prolonged drought.
- Fungal diseases, such as powdery mildew, gray mold, or leaf spots.
- Clogged soil or stress from temperature changes.
