Regarding Lantana and lace — can I cut damaged limbs then spray neem oil? If I do that will it flower?
This usually happens every year! One season spraying did not help? They are in a sunny spot with dome shade in the morning.
Neem Oil is a great organic solution for most pests and can help act as a fungicide.
Make sure you follow the directions on the container.
Spray plants in the early am; not during full sun.
You may need to make more than one application.
