Hey everyone. I have a dwarf satsuma potted up in a 5 gallon container. It suffered from frost damage in my greenhouse this past year. It also had some type of damage from scale or weevle bug IM pretty sure. It was the white sticky material on the foliage. How should I treat this problem? I was thinking about spraying with horticultural oil since it is that time of year for using it since everything is still dormant. Am I on the right track or should I do something different. IM also getting leaf drop which is partially from the frost damage but also Im getting light yellowing of leaves around the edges. What method should I use. thanks
