Mauget Stemix Plus is a formulation of low salt index N-P-K plus chelated micro-nutrients, with added Magnesium and Calcium. This product is for use in trees where nutrient deficiencies cannot be easily treated using traditional foliage or root fertilization methods - for example, in areas where spraying would be prohibitive or where nutrient leaching into ground water would be a concern.

Introducing fertilizers and trace minerals directly into the vascular system of the tree ensures quick response - improvement can usually be seen within a couple of days. These improvements in color and vitality have been shown to persist for up to 5 years compared to adjacent untreated trees.
