Why Are My Little Gem Southern Magnolia Tree Leaves Turning Brown and Falling?
Causes of Brown and Falling Magnolia Leaves
1. Drought Stress: Magolias prefer consistently moist soil and can develop brown leaves when under-watered. 2. Nutrient Deficiency: A lack of magnesium or iron can lead to yellowing or browning of leaves. 3. Fungal Diseases: Diseases like fungal leaf spot and anthracnose can cause brown spots and leaf drop. 4. Insect Infestations: Aphids, scales, and other insects can feed on leaves, sucking out nutrients and causing browning. 5. Environmental Factors: Exposure to excessive heat, wind, or cold can damage leaves.
How to Resolve the Issue
1. Check Soil Moisture: Water the magnolia tree deeply and regularly, especially during dry periods. 2. Fertilize Regularly: Apply a balanced fertilizer to provide essential nutrients. 3. Treat Fungal Diseases: Use a fungicide to control fungal infections. 4. Control Insects: Spray with an insecticidal soap or organic pesticides to manage insect infestations. 5. Provide Protection: Mulch around the tree to retain moisture and shelter roots from temperature extremes.
