To manage aphids, it is advisable to spray the plant with insecticidal soap or horticultural oil. Encouraging natural predators like ladybugs might also help control the infestation.
Spider Mites
Spider mites are tiny pests that might cause the leaves to turn yellow and develop a stippled appearance. They might also cause the plant to lose vigor and curl up. To manage spider mites, it is advisable to spray the plant with water regularly to increase humidity. Insecticidal soap or horticultural oils might be necessary for severe infestations.
Proper plant care practices such as adequate watering, fertilization, and pruning might help prevent pest and disease infestations. It is advisable to keep plants healthy and monitor them regularly for signs of pests and disease.
