Wicked Organics 10-2-8 Fertilizer

High Nitrogen, Released Slowly — Season-Long Feeding for Turf and Fruit Trees

Old Cobblers Farm Wicked Organics 10-2-8 is the highest-nitrogen feed in our organic line — but the way it delivers that nitrogen is the whole point. Of the 10% total, 9% is water-insoluble nitrogen from feather meal and meat & bone meal, released gradually by soil microbes through the season. So you get the strong, sustained feeding of a high-N product without the flush, leaching, or burn that fast nitrogen causes. It's a true all-season feed for turf and landscapes, and an excellent dedicated fruit-tree fertilizer for young and mature trees alike. The 8% potassium is high for good reason: it supports fruit size, color, flavor, sugar (brix), and firmness, and it backs drought and stress tolerance in turf and trees. The 2% phosphorus supports early root development and blossom establishment, and guaranteed calcium (1.8%) and sulfur (3%) round out cell-wall strength and metabolism.

On fruit trees — apple, pear, stone fruit (peach, plum, apricot), and citrus (lemon, orange, lime) — feed in early spring before bud break and again mid-season after fruit set, with an optional light fall feeding for winter hardiness. On turf, it's a season-long maintenance feed, especially effective applied during or after core aeration and useful ahead of overseeding. It also suits landscape beds, shrubs, and vegetable gardens where steady, sustained growth matters.

One important note: this blend is made from feather meal, meat & bone meal, and blood meal, so it is firmly not a vegan product, and because of the blood and bone content it can strongly attract dogs and other animals — incorporate it well and store it securely.

Key Benefits

High N, released slowly — Of the 10% nitrogen, 9% is water-insoluble and released slowly by soil microbes — strong, season-long feeding without the flush, leaching, or burn of fast nitrogen.

Fruit quality — 8% potassium supports fruit size, color, flavor, sugar (brix), and firmness in apples, pears, stone fruit, and citrus.

For every tree stage — Feeds young and mature fruit trees alike — early spring before bud break and after fruit set, with an optional fall feeding.

All-season turf too — A true all-season turf feed for warm- and cool-season grass, especially effective with core aeration and ahead of overseeding.

Added Ca & S — Guaranteed calcium (1.8%) and sulfur (3%) support cell-wall strength and metabolism beyond basic N-P-K.

Feeds soil biology — Natural protein-meal inputs feed soil microbes, improving nutrient cycling and long-term fertility.

Where to use it: apple, pear, stone fruit, and citrus trees, young or mature; all-season turf (warm- and cool-season); overseeding and renovation; and landscape beds, shrubs, and vegetable gardens.
