Why does my lemon tree have yellow leaves with spots?
When your lemon tree develops yellow leaves with spots, it can be a sign of several underlying issues. Here are the most common causes:
1. Nutrient deficiency: Yellowing of leaves with spots can indicate a deficiency in important nutrients, such as nitrogen, magnesium, or iron. 2. Pest infestation: Spider mites, aphids, and other pests can feed on the leaves of your lemon tree, causing yellowing and spotting. 3. Fungal diseases: Fungal diseases like anthracnose or Alternaria leaf spot can also cause yellow leaves with spots. 4. Watering problems: Both overwatering and underwatering can stress your lemon tree, leading to yellow leaves with spots. 5. Sunburn: Excessive exposure to direct sunlight can scorch the leaves of your lemon tree, resulting in yellowing and spotting.
