Root Rot

Overwatering

To address root rot in magnificent croton, 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 pot sit in standing water.

Spider Mite Infestation

Spider mites are tiny pests that thrive in warm, dry conditions. They feed on the sap of the magnificent croton, causing yellowing, speckled leaves, and potentially leading to leaf drop.

To combat spider mite infestations, increase humidity around your croton, as these pests prefer dry environments. Regularly misting the plant can help. For severe infestations, rinse the plant under a gentle stream of water to dislodge the mites, or use an insecticidal soap or neem oil, applying it carefully according to the product's instructions. Ensure to treat the undersides of the leaves where mites commonly reside. Repeat the treatment every 7-10 days until the infestation is under control.
