Product Description

Deep Green, All Four Seasons — Balanced 10-10-10 Nutrition with Added Iron

Old Cobblers Farm Wicked Growth 10-10-10 + Iron is a balanced evergreen fertilizer with one addition that matters enormously to conifers and broadleaf evergreens: iron. The 10-10-10 analysis supplies equal parts of the three major nutrients — 10% nitrogen for steady foliage growth, 10% phosphorus for strong root establishment, and 10% potassium for resilience through seasonal change — while added iron (as iron sulfate) supports chlorophyll production, helping prevent the yellowing caused by iron deficiency and keeping needles and leaves a rich, deep green.

Evergreens are valued precisely because they hold their color year-round, and iron is central to that: when evergreens can't get enough of it, foliage fades and yellows (a condition called chlorosis) even when everything else is right. This fast-acting granular formula pairs complete balanced feeding with that iron support, for new plantings and established trees and shrubs alike.

Key Benefits

Iron for true evergreen color — Added iron supports chlorophyll production and helps prevent the yellowing caused by iron deficiency — the difference between dull and deep green needles.

Complete balanced nutrition — Equal 10-10-10 nitrogen, phosphorus, and potassium feed foliage, roots, and overall strength together.

Conifers and broadleaf alike — One formula for towering pines and spruces, hedging arborvitae, and broadleaf evergreens like hollies, boxwoods, rhododendrons, and azaleas.

Fast-acting granular formula — Fast-acting granules dissolve with watering and move nutrients into the root zone quickly.

Rates that scale — Simple physical rates — 1 lb per 10 ft of dripline for trees, 2–3 lbs per 100 sq ft for hedges — scale from one specimen tree to a full privacy screen.

Any age of planting — Suits both new plantings and established trees and shrubs.

Where to use it: specimen trees, privacy hedges, and foundation plantings of pines, spruces, cedars, arborvitae, hollies, boxwoods, rhododendrons, azaleas, and other landscape and ornamental evergreens.

Application Instructions

-Trees: 1 lb per 10 feet of dripline (the dripline is the circle on the ground under the outer edge of the branches — measure around it)
-Hedges and shrub beds: 2–3 lbs per 100 sq ft
Steps:
1. Measure the rate for your tree or hedge area.
2. Sprinkle evenly around the root zone, out to the dripline, keeping granules off foliage and away from direct contact with trunks and stems.
3. Water thoroughly to dissolve the granules and carry nutrients into the root zone.
What NOT to do: do not exceed the listed rates, do not pile granules against trunks or stems, and do not skip the watering-in step.

Ingredients

Urea (10–20%) — Provides fast-acting nitrogen that fuels foliage growth.

Diammonium Phosphate / DAP (10–20%) — Supplies phosphorus for root development, plus a secondary nitrogen contribution.

Potassium Chloride (40–50%) — Also called muriate of potash; the potassium source that builds resilience and stress tolerance.

Iron (as Iron Sulfate, % TBC) — Supports chlorophyll production and deep green color; helps prevent iron-deficiency yellowing (chlorosis).
