One factor NOT to do throughout fall is apply an insecticide to soil or plant particles. Over time, I’ve been requested if spraying the soil will kill bugs. Whereas some bugs do spend the winter in soil, plant injury can’t be managed this manner.
When utilizing any pest administration observe, ensure it’s concentrating on the right pest on the proper time. Positively establish the reason for plant injury.
