Stark® Tre-Pep® Fertilizer

Stark® Tre-Pep® is our own concentrated fertilizer formula, developed specifically for the trees, shrubs, and plants we sell and used by Stark Bro’s growers from the first day of planting. The 22-24-12 formula reflects a deliberate nutritional priority: high phosphorus to drive root development and earlier fruiting, meaningful potassium for plant health and stress resilience, and balanced nitrogen for vigorous growth without pushing excessive leaf growth at the expense of fruit. Mix one tablespoon per gallon and apply to the root zone — trees bear sooner, plants establish faster, and the difference shows from the first growing season.

• 13 oz. package makes 21 gallons
• 5 lb. package makes approximately 129 gallons

Mix with water: one tablespoon per gallon. Use 1-2 gallons for shrubs and trees; 1-2 quarts for roses.

22-24-12 — The Formula Behind Earlier Fruiting

The NPK ratio tells the story of what Tre-Pep® is built to do. The high phosphorus (24) is the most important number for home orchardists: phosphorus drives root cell development, supports flower bud formation, and is the primary nutrient responsible for earlier and more consistent fruit set. The potassium (12) supports overall plant vigor, stress tolerance, and fruit quality. The nitrogen (22) feeds healthy green growth without the excessive vegetative push that high-nitrogen formulas can produce at the cost of fruiting. Together the three support the outcome that matters most: trees that establish quickly and bear fruit sooner.

Stark Bro’s Own Formula — For Every Tree and Plant We Sell

Tre-Pep® is a Stark Bro’s product, not a third-party fertilizer we carry alongside our catalog. It was formulated for the trees and plants we grow and sell, and it’s what our growers use. That makes it a natural first choice for any new tree, shrub, berry, or flower planting — one tablespoon per gallon of water, one to two gallons per tree or shrub, applied to the root zone at planting and through the establishment phase.

Highly Concentrated — Exceptional Value Per Package

The concentrated formula means a small package goes a long way. A 13 oz. package mixes into 21 gallons of ready-to-use fertilizer solution. A 5 lb. package makes approximately 129 gallons — enough to feed an entire home orchard through multiple growing seasons from a single purchase.
