Why are my tomato plant leaves turning yellow? 5 steps to save your harvest
Yellowing tomato plant leaves often indicate issues with growing conditions such as nutrient deficiencies, watering problems, pests, or diseases. Identifying the specific cause is essential to effectively treat and restore plant health. Proper care including balanced fertilization, consistent watering, pest control, and disease management can save the harvest.
- ▪Nitrogen deficiency is a primary cause of yellowing leaves, typically starting at the bottom of the plant and moving upward.
- ▪Overwatering or inconsistent watering can suffocate roots and lead to yellow leaves due to poor nutrient absorption.
- ▪Pests like aphids and spider mites damage leaves by sucking plant juices, causing yellowing and curling.
- ▪Fungal infections or diseases often cause yellowing that starts at the top of the plant and progresses downward.
- ▪Watering at the base of the plant and using pest-repelling companion plants can help prevent yellowing and promote healthy growth.
