If the Bottom Leaves of a Zucchini Plant Have Turned Yellow Does This Indicate Over or Under Watering?
When the bottom leaves of a zucchini plant turn yellow, it is often a sign of water stress. However, the cause of the water stress can be either overwatering or underwatering.
Overwatering
Yellowing of the bottom leaves can occur when a zucchini plant is overwatered. Overwatering can lead to root rot, which prevents the plant from absorbing water and nutrients from the soil. The roots may also become waterlogged, which can also lead to yellowing of the bottom leaves.
Underwatering
Underwatering can also cause the bottom leaves of a zucchini plant to turn yellow. When a plant is underwatered, it cannot get the water it needs to carry out photosynthesis, which is the process by which plants convert sunlight into energy. This lack of energy can lead to yellowing of the bottom leaves.
Other Causes
In some cases, the yellowing of the bottom leaves of a zucchini plant may not be due to water stress. Other possible causes include:
- Nutrient deficiency
- Disease
- Pest infestation
If you are not sure what is causing the yellowing of the bottom leaves of your zucchini plant, it is best to consult with a plant expert.
