ROOT-jet Magnesium is formulated for greening the foliage of conifers in coastal regions, where precipitation is high and mineral leaching is likely to occur. Magnesium is an essential mineral component of chlorophyll, needed for photosynthesis and carbohydrate production. This plant fertilizer enhances needle greening without added nitrogen, a benefit where piercing-sucking or defoliator pests are a problem. It is therefore compatible with plant health programs designed to minimize pest damage and enhance plant resistance.
