To manage root rot, remove the affected plant from the soil and cut off any rotten roots. Repot the plant in fresh, well-draining soil.
Pests
1. Spider Mites: Spider mites are tiny pests that can cause serious damage to Grielum sinuatum. They feed on the sap of the plant, causing the leaves to turn yellow and brown and fall off. To manage spider mites, wipe the leaves with a damp cloth to remove them. You can also use insecticidal soap to kill them.
2. Aphids: Aphids are small, soft-bodied insects that feed on the sap of the plant. They can cause yellowing and curling of the leaves, as well as the development of sooty mold. To manage aphids, wash them off the plant with a strong stream of water. You can also use insecticidal soap or neem oil to kill them.
