How can I determine the severity of a scale infestation on my olive tree and effectively treat it?

To determine the severity of a scale infestation on your olive tree, carefully inspect the leaves, branches, and trunk for small, oval-shaped insects. If you notice a significant presence of scales, it may indicate a severe infestation. To effectively treat it, you can use horticultural oil or insecticidal soap to suffocate and kill the scales. Pruning heavily infested branches and improving tree health through proper watering and fertilization can also help control the infestation.
