Overview
What It Is
Old Cobblers Farm™ Evergreen Fertilizer is a balanced 10-10-10 granular fertilizer enhanced with iron sulfate, specifically designed for evergreen species that maintain foliage year-round. The iron addition sets it apart from standard 10-10-10 — evergreens are particularly susceptible to iron chlorosis (yellowing) especially in alkaline soils, and the supplemental iron ensures deep green color.
Nitrogen fuels new growth and enhances leaf density. Phosphorus encourages strong roots and establishment. Potassium helps withstand heat, drought, and disease stress. Iron sulfate boosts chlorophyll production for rich, dark green color.

Crop Fit
Best For
Pines and spruces are the classic evergreen conifers that benefit from balanced feeding plus iron for needle color. Arborvitae and cedars used in hedges and screening need consistent nutrition for dense growth. Hollies and boxwoods are broadleaf evergreens that maintain foliage year-round. Rhododendrons and azaleas benefit from the iron and balanced nutrition for vibrant foliage and seasonal blooms.
Application Rates
How Much to Use
| Garden & beds | 1-2 lbs per 100 sq ft for beds and foundation plantings |
|---|---|
| Lawn | N/A — formulated for evergreen trees and shrubs, not turf |
| Trees & shrubs | 1 lb per inch of trunk diameter for large trees; 0.5 cups per foot of height for shrubs |
| Containers | 1 tablespoon per gallon of container soil |
| Frequency | 1-2 times per season (spring, optional early summer) |
Step by Step
How to Apply
1
Measure
Measure correct amount based on plant size and bed area. Refer to label for specific rates.
2
Broadcast
Broadcast evenly around plants, avoiding direct trunk/stem contact which can cause bark damage.
3
Incorporate
Lightly rake into the top 1–2 inches of soil for better nutrient contact and reduced surface runoff.
4
Water In
Water thoroughly to activate the fast-acting granular formula and move nutrients into the root zone.
Apply according to plant size and bed area. For foundation plantings and hedges, broadcast evenly over the root zone. For specimen trees, apply around the drip line. Water in thoroughly after application. Apply in early spring and optionally again in early summer for actively growing evergreens.
Handling & Timing
Safety & Season
Safety & Storage
Store in a cool, dry place. Iron sulfate can stain concrete and clothing — apply carefully and sweep any spills from hard surfaces. Wear gloves when handling.
Seasonal Notes
Apply in early spring when growth resumes. Optional second application in early summer for actively growing specimens. Avoid late fall application to prevent tender new growth before winter. Fast-acting granular formula activates quickly when watered in.
In Context
How It Compares
This formula adds iron sulfate to the standard 10-10-10 base — the key differentiator for evergreens. Standard balanced fertilizers won't address iron chlorosis, which is the most common nutrient deficiency in evergreen species. The iron addition makes this a purpose-built evergreen formula.
Answers
Frequently Asked Questions
What is the best organic fertilizer for evergreen trees?
The best organic evergreen fertilizer provides balanced nutrition from natural, slow-release ingredients with adequate nitrogen for foliage color and density. An organic formula made from protein meals, bone char, and sulfate of potash delivers steady NPK nutrition while building soil health around the root zone. Organic fertilizers are especially beneficial for evergreens because the slow-release action feeds trees gradually without the growth surges that can produce weak, frost-susceptible new growth. Old Cobblers Farm™ Wicked Organics Organic Evergreen Fertilizer provides gentle, sustained nutrition for naturally healthier evergreen trees.
When should I fertilize evergreens organically?
Apply organic evergreen fertilizer in early spring, 2–4 weeks before bud break, to give soil microbes time to process the organic ingredients and make nutrients available when the tree needs them most. A second application in early fall supports root growth before winter dormancy. Because organic fertilizers release nutrients slowly, timing the application slightly earlier than you would with synthetics ensures peak nutrient availability coincides with peak growth. Old Cobblers Farm™ Wicked Organics Organic Evergreen Fertilizer is designed for spring and fall applications that match the natural growth cycle of conifers and broadleaf evergreens.
How much organic fertilizer for evergreen trees?
For established evergreen trees, apply 1–3 pounds of organic fertilizer per inch of trunk diameter, broadcast under the canopy drip line. For evergreen hedges and foundation plantings, use 3–5 pounds per 100 square feet of bed area. For container evergreens, apply 1–2 tablespoons per gallon of soil. Because organic fertilizer concentrations are lower than synthetics, application rates are higher but the risk of burn is dramatically lower. Old Cobblers Farm™ Wicked Organics Organic Evergreen Fertilizer is gentle enough for safe application at these rates.
Can I use organic evergreen fertilizer on all types of evergreens?
Yes, organic evergreen fertilizer works on all evergreen types including pines, spruces, firs, cedars, hemlocks, arborvitae, junipers, hollies, boxwoods, rhododendrons, azaleas, and camellias. The balanced organic formula supports healthy foliage, strong roots, and disease resistance across both coniferous and broadleaf evergreens. For acid-loving species like rhododendrons and azaleas, supplementing with elemental sulfur may help maintain optimal soil pH. Old Cobblers Farm™ Wicked Organics Organic Evergreen Fertilizer is versatile enough for any evergreen in your landscape.
What is the difference between organic and synthetic evergreen fertilizer?
Organic evergreen fertilizer releases nutrients gradually as soil organisms break down natural ingredients, providing steady feeding over weeks to months. Synthetic evergreen fertilizer delivers nutrients immediately for faster visible results. Organic products build soil health, improve soil structure, and support beneficial microorganisms around the tree's root zone. Synthetics do not provide these soil-building benefits. Organic fertilizers carry virtually no burn risk, while synthetics can damage roots if over-applied. Old Cobblers Farm™ offers both Wicked Organics Organic Evergreen Fertilizer and Wicked Growth Evergreen 10-10-10 with Iron to match your preferences.
Will organic fertilizer make my evergreens greener?
Yes, organic fertilizer improves evergreen color by providing steady nitrogen and micronutrients that support chlorophyll production. The gradual nutrient release produces consistent, deep green color rather than the bright green flush followed by fading that can occur with synthetic fertilizers. Over time, the soil health improvements from organic fertilization also enhance nutrient availability and uptake efficiency, producing naturally greener, healthier trees. Old Cobblers Farm™ Wicked Organics Organic Evergreen Fertilizer promotes rich, lasting green color through natural, sustained nutrition.
Is organic evergreen fertilizer OMRI-Listed?
Yes, Old Cobblers Farm™ Wicked Organics Organic Evergreen Fertilizer is OMRI-Listed for certified organic production. All ingredients meet the strict standards of the Organic Materials Review Institute, containing only approved natural sources with no synthetic chemicals or prohibited substances. This certification is important for organic landscapers, nurseries, and homeowners who want to maintain truly organic growing practices. Old Cobblers Farm™ Wicked Organics carries the OMRI seal across its entire organic product lineup.
