Old Cobblers Farm™ Wicked Organics Fruit Tree Fertilizer
Organic 12-2-8 fruit tree fertilizer — highest nitrogen organic formula for apples, peaches, pears & more. OMRI Listed. Rates & tips from Old Cobblers Farm.
Old Cobblers Farm™ Wicked Organics Fruit Tree Fertilizer
Wicked Organics Fruit Tree Fertilizer is a 12-2-8 organic granular blend formulated from Feather Meal, Meat and Bone Meal, Blood Meal, and Sulfate of Potash. The formula delivers the highest total NPK concentration in the Wicked Organics line — 22% combined nutrients per pound — specifically calibrated for the heavy feeding demands of fruit-bearing trees.
The high nitrogen content (12%) is predominantly in slow-release water-insoluble form from the protein meal sources, releasing gradually through microbial decomposition over weeks. This steady-state delivery matches how fruit trees actually use nitrogen — in sustained doses throughout the growing season rather than one massive spring flush that produces excessive vegetative growth at the expense of fruit production.
The 8% potassium from sulfate of potash is critical for fruit trees because potassium directly controls fruit quality: sugar content, firmness, color development, and storage life. Potassium also regulates water movement through plant cells and improves cold tolerance — essential for fruit trees in northern growing zones.

What Is It ?
Organic Fruit Tree Fertilizer (12-2-8) is the highest-nitrogen organic blend in the Wicked Organics lineup, purpose-built for the demanding nutritional needs of fruit-bearing trees. Fruit trees are uniquely hungry plants — they must simultaneously maintain a large photosynthetic canopy, produce heavy crops of energy-dense fruit, and store enough reserves in roots and wood to survive winter and bloom again the following spring. This requires more nitrogen than most organic fertilizers provide, which is why the 12-2-8 formula delivers 12% organic nitrogen from slow-release protein meal sources that feed steadily through microbial activity rather than overwhelming trees with a single nutrient spike. The 8% potassium — tied for the highest in the organic line — drives the fruit quality outcomes that matter most to orchardists and home growers: larger fruit, better flavor, improved firmness, enhanced color, and stronger winter hardiness. The intentionally low 2% phosphorus reflects the reality that most established fruit tree sites have adequate phosphorus from years of fertilization and organic matter cycling. Old Cobblers Farm™ Wicked Organics Fruit Tree Fertilizer gives organic orchardists and backyard fruit growers the concentrated nutrition their trees need without the burn risk, leaching, or synthetic inputs that compromise organic certification.
When To Apply ?
For established fruit trees, apply 1-2 lbs per inch of trunk diameter, measured at 4 feet above ground. Broadcast granules evenly in a ring from 1 foot from the trunk out to and slightly beyond the drip line — this is where the active feeder roots are concentrated. For young trees in their first 3 years, reduce rates to 0.5 lb per inch to avoid overstimulating growth before the root system is fully established. The primary application should be in early spring before bud break when trees are emerging from dormancy and beginning active nutrient uptake. A second application in mid-summer after fruit set supports the heavy nutritional demands of fruit development. For commercial orchards, apply 300-500 lbs per acre split between spring and summer applications. Water in after application to activate microbial breakdown.
How to Apply ?
1.
Measure Trunk
Measure trunk diameter at 4 feet above ground (diameter at breast height) for accurate rate calculation.
2.
Established Tree Rate
Apply 1–2 lbs per inch of trunk diameter for established trees (4+ years). Larger trees need more.
3.
Young Tree Rate
For young trees (1–3 years), use 0.5 lb per inch of trunk diameter to avoid over-stimulating growth.
4.
Application Area
Broadcast evenly from 1 foot from the trunk out to the drip line covering the entire feeder root zone.
5.
Avoid Trunk Contact
Do not pile fertilizer against the trunk. Direct contact invites disease, rot, and pest damage.
6.
Water In
Water thoroughly after application to begin activating organic nutrient release.
7
Young Tree Rate
For young trees (1–3 years), use 0.5 lb per inch of trunk diameter to avoid over-stimulating growth.
How To Store
Store in a dry environment. Natural product. Wear gloves if skin sensitivities appear. Wear approved respirator if sensitive to dust. Eye protection optional. Wash hands after use. Keep away from water sources.
FAQs
1.
What is the best organic fertilizer for fruit trees?
The best organic fruit tree fertilizer provides balanced nutrition from natural, slow-release ingredients that support both tree health and fruit quality. An organic formula with moderate nitrogen for canopy growth, phosphorus for root and flower development, and potassium for fruit size, flavor, and storage quality delivers complete nutrition without the burn risk of synthetic fertilizers. The slow-release action feeds trees steadily throughout the season. Old Cobblers Farm™ Wicked Organics Fruit Tree Fertilizer is specifically formulated for organic apple, peach, pear, plum, cherry, and citrus tree care.
2.
When should I fertilize fruit trees organically?
Apply organic fruit tree fertilizer in early spring, 2–4 weeks before bud break. Because organic ingredients need time for soil microbes to process them into plant-available nutrients, applying earlier than you would with synthetics ensures peak availability during the critical flowering and fruit-set period. A lighter second application after fruit set supports developing fruit. Avoid late-season application that could stimulate tender growth before winter. Old Cobblers Farm™ Wicked Organics Fruit Tree Fertilizer is designed for spring application timing that aligns with organic nutrient release.
3.
How much organic fertilizer for fruit trees?
For established fruit trees, apply 1–2 pounds of organic fertilizer per inch of trunk diameter, broadcast under the canopy drip line. For young trees (1–3 years), use ½–1 pound total. For dwarf or semi-dwarf varieties, use the lower end of the rate range. Spread evenly, lightly incorporate into the top inch of soil, and water deeply. Because organic fertilizer concentrations are lower than synthetics, application rates are higher but burn risk is minimal. Old Cobblers Farm™ Wicked Organics Fruit Tree Fertilizer is forgiving and safe at recommended rates.
4.
What fruit trees can I fertilize with organic fruit tree fertilizer?
Organic fruit tree fertilizer works on all deciduous and evergreen fruit trees, including apples, pears, peaches, plums, cherries, apricots, nectarines, figs, persimmons, and citrus. It also benefits nut-producing trees like almonds, pecans, and walnuts. The balanced organic formula supports the diverse nutritional needs of different fruit tree species while building long-term soil health in the root zone. Old Cobblers Farm™ Wicked Organics Fruit Tree Fertilizer is versatile enough for mixed-species home orchards and dedicated single-variety plantings.
5.
Does organic fruit tree fertilizer improve fruit flavor?
Yes, organic fertilization can improve fruit flavor by providing a broader spectrum of nutrients and micronutrients than simple synthetic formulas, and by building healthier soil biology that enhances nutrient uptake. The slow-release action of organic ingredients provides steady, balanced nutrition that avoids the growth surges and nutrient spikes associated with synthetics. Many orchardists report that organically grown fruit develops more complex flavor profiles, better sweetness, and improved aroma. Old Cobblers Farm™ Wicked Organics Fruit Tree Fertilizer supports premium fruit quality through natural, soil-building nutrition.
6.
What ingredients are in organic fruit tree fertilizer?
Wicked Organics Fruit Tree Fertilizer is formulated from vegetable protein meals, animal protein meals, bone char, natural sulfate of potash, and nitrate of soda. These OMRI-Listed ingredients provide a complete nutrient profile including nitrogen for canopy growth, phosphorus from bone char for root health and flowering, and chloride-free potassium from sulfate of potash for fruit quality. The organic ingredients also deliver secondary nutrients like calcium, sulfur, and trace minerals. Old Cobblers Farm™ Wicked Organics uses only premium natural ingredients for safe, effective organic fruit tree nutrition.
