Too much water drowns the roots, making leaves turn yellow. Let the soil dry slightly before watering again to prevent root rot and keep your tree healthy.
Dry soil causes stress, leading to yellowing leaves. Water deeply but less frequently, ensuring the soil stays moist but not soggy for strong, green growth.
Lack of nitrogen, iron, or magnesium causes yellow leaves. Use a citrus fertilizer to provide the right nutrients and restore vibrant, healthy foliage.
Aphids, spider mites, and scale insects suck nutrients, turning leaves yellow. Check under leaves and use neem oil or insecticidal soap to keep pests away.
Cold weather or sudden temperature changes shock your lemon tree, causing yellowing. Protect it from frost and avoid placing it in extreme heat.
Compacted or waterlogged soil prevents roots from absorbing nutrients. Use well-draining soil and pots with drainage holes to avoid root suffocation.
Lemon trees need at least 6–8 hours of sunlight daily. If placed in shade, leaves may yellow. Move your tree to a sunnier spot for healthier growth.
