Description
Stark® Orchard Fertilizer is a pure 45-0-0 nitrogen formula — the highest-nitrogen granular fertilizer available for home orchards — designed for the single most important annual feeding a fruit tree needs: the early spring boost that drives the vigorous vegetative growth that strong canopy, healthy branch structure, and productive fruiting wood depend on. One application per year, spread on the ground under trees about two weeks before new growth emerges, delivers a full season of nitrogen support from a single efficient treatment. A Stark Bro’s exclusive.
Apply 1/4 pound per inch of tree-trunk diameter, spread evenly under the canopy from the trunk to the drip line.

45-0-0 — Pure Nitrogen for Vegetative Growth
The 45-0-0 formula is pure urea nitrogen with no phosphorus or potassium — and that’s by design. Orchard Fertilizer targets the specific nutritional need of the early spring growth phase: maximum nitrogen availability to support rapid leafing out, strong new shoot extension, and the vigorous canopy growth that supports fruiting wood through the season. Phosphorus and potassium are already present in most orchard soils and are addressed at planting; the annual early spring feeding is specifically a nitrogen need, and 45-0-0 delivers it at the highest concentration available in granular form.
Once Per Year — Two Weeks Before New Growth Emerges
The single annual application timing is one of Orchard Fertilizer’s most practical qualities. Spread on the ground under trees about two weeks before new growth emerges in early spring — typically late February through March depending on your zone — and let rainfall and soil activity move the nitrogen into the root zone where it’s available as growth begins. One application, one treatment per season, no repeat applications required through the growing year.
Apply by Trunk Diameter — Simple, Precise Dosing
The application rate scales simply to tree size: 1/4 pound per inch of trunk diameter measured at knee height. A tree with a 4-inch trunk diameter gets 1 pound. A tree with an 8-inch trunk gets 2 pounds. Spread evenly under the canopy from the trunk to the drip line and water in if rainfall isn’t expected within a few days.
