Product Features

High nitrogen formula. Good for outdoor landscape or containers, even smaller ones like 1-gallon. Tablets have a 2-year nutrient release. Can be used to feed trees, shrubs, roses, vines and perennials of all sorts. Also can be used on established evergreens.

Product Benefits

High nitrogen formula is good for overall size and green leaves. The landscape or container application makes it a versatile tablet. The 2-year formula is time saving and money saving; you don't have to put them in very often, and you are not limited to when you can put them in like you would a 3 or 4 month formula, because of the variety of plants that feed from these tablets, you will not have to buy many different formulas for each plant you sell or grow.
