Root Rot

Overwatering

To address root rot in Scarlet Star, first, cease watering immediately and allow the soil to dry out. If the plant is severely affected, remove it from its pot, trim away any black, mushy roots, then repot in fresh, well-draining soil. Ensure the pot has adequate drainage holes. Going forward, water only when the top inch of soil feels dry to the touch, and avoid letting the plant sit in standing water.

Leaf Tip Burn

Underwatering

Leaf tip burn in Scarlet Star plants is often a sign of underwatering, which leads to dehydration and the inability of the plant to transport nutrients effectively. To resolve this, establish a consistent watering schedule, ensuring the soil remains slightly moist but not waterlogged. Use lukewarm water to avoid shocking the plant's roots. If the soil dries out too quickly, consider repotting the plant into a slightly larger container with fresh, well-draining potting mix to retain moisture more effectively.

Leaf Spot

Fungal or bacterial pathogens

Leaf spot can be a common issue in Scarlet Star plants, often resulting from fungal or bacterial infections. To manage this, ensure good air circulation around your plant and avoid wetting the leaves when watering. If spots appear, remove the affected leaves carefully to prevent the spread of the disease. For severe infections, applying a fungicide or bactericide, as appropriate, following the product's instructions, can be effective. Always sterilize your pruning tools after use to avoid spreading the pathogens.
