Injecting insecticides into the soil around a tree is a very effective and efficient way to keep a tree protected from insects like the Hemlock Woolly Adelgid (HWA), Emerald Ash Borer (EAB), Bronze Birch Borer, Scale, Aphids and Japanese Beetles.
Managing some insects requires an annual injection, while others are controlled with just one and done.
Soil injections can also be used to inject fertilizers, from specific nutrients to balanced fertilizers.
Fall fertilization is most commonly done on deciduous trees, but Spring is a very good time to fertilize evergreens.
Tree Growth Regulators (TGR's) can be used to decrease the top growth of a tree, while increasing its fine root production. This is used for lightening-struck trees or trees around construction sites or in other areas where a tree might be under stress.
