Mauget’s Inject-A-Min Iron/Zinc is a micro-nutrient formulation used in Gen II injection capsules containing water-soluble iron and zinc sulfates including Sulfur, together helping to correct conditions of many tree species growing in non-native alkaline soils.
Inject-A-Min Iron/Zinc is very helpful in correcting Iron and or zinc deficiencies in many trees including Pin Oaks.
Because these elements are placed directly into the trees vascular system, the benefits of Inject-A-Min Iron-Zinc can be evident for one to five years compared to adjacent untreated trees. In most cases the results of Inject-A-Min Iron/Zinc are apparent quickly.
Iron and zinc deficiencies are characterized by young leaves exhibiting darker green veins with a yellowing or loss of color between veins.
