Old Cobblers Farm™ Wicked Organic Tomato

Balanced, Slow-Release Nutrition for Flavorful Tomato Harvests

Get ready for bigger, tastier tomatoes with Wicked Organics Tomato Fertilizer 5-3-4, a premium organic blend crafted to support tomatoes from seedling through harvest. If you’ve been looking for “organic fertilizer for tomatoes that boosts fruit flavor,” “balanced slow-release tomato plant food,” or “tomato fertilizer for consistent blossom & fruit set,” this is the formula built to deliver.

Nutrient Profile & Function

Total Nitrogen (N): 5.0%
 • Includes ~1.5% water-soluble nitrogen for early green-up and ~3.5% water-insoluble nitrogen for ongoing, steady feeding.

Available Phosphate (P₂O₅): 3.0% — Helps root establishment, bloom production, and supports fruit set when tomatoes begin flowering.

Soluble Potash (K₂O): 4.0% — Enhances fruit firmness, color, sugar content, and water regulation, helping tomato fruit resist splitting and stress.

All drawn from natural inputs (vegetable & animal protein meals, natural sulfate of potash, phosphate rock, natural nitrate), this blend supports soil biology and builds soil structure over time. It avoids harsh spikes, which is especially important for tomatoes that can suffer from blossom-end rot or leaf burn under excessive synthetic N.

Why This Fertilizer Works — Backed by Garden Science

Tomato plants need a balanced supply of nutrients: enough nitrogen for foliage and vine growth, sufficient phosphorus for root and bloom formation, and adequate potassium to support fruit quality and stress resistance. Guides often recommend feeding tomatoes starting from transplanting, and again at bloom/fruit set stages, using fertilizers with ratios similar to this. 
 

Slow-release fertilizers feed not just the plant, but also soil microbes, which help unlock micronutrients and improve overall plant health. Organic fertilizers reduce risk of overfertilization, nutrient leaching, and salt damage. 
 

Key Benefits for Tomato Growers

Steady, balanced growth — supports healthy foliage without excessive leaf growth that can shade fruit or slow ripening.

Better blossom & fruit development — phosphorus supports blooms, potassium helps fruit set, size, flavor, and shelf life.

Improved soil biology & structure — feeds soil living organisms that help nutrients become available naturally.

Non-burning, plant-safe formula — gentle enough for both seedlings and mature plants.

Flavor & Nutrient Density — produces fruit that tastes richer, with better texture and longer freshness after harvest.

How to Use It — Application Guidelines

• pre-plant / Bed Preparation – Mix 5–7 lbs per 100 sq ft into the topsoil before planting to establish a strong nutrient foundation.

• Transplanting – Add 1–2 tablespoons into the planting hole (mix with soil) to encourage early root development.

• Bloom & Fruit Set / Side-Dressing – Apply ½ cup per plant every 4–6 weeks during flowering and fruiting to maintain steady nutrition.

• Container Tomatoes – Mix 2–3 tablespoons per gallon of potting soil; ensure even mixing and provide adequate watering.

Always water in thoroughly after application to activate soil microbes and ensure nutrient release. Adjust applications depending on soil test results and climate (hot, rainy, or nutrient-leaching soils may require light reapplications).

Great For These Types of Tomatoes & Settings

Heirloom & large slicing tomatoes needing extra flavor and size

Cherry, grape, and smaller fruiting varieties that benefit from steady nutrient supply

Container tomato plants or raised beds where nutrients wash out more quickly

Hot or humid climates where steady, long-term feeding helps prevent stress, blossom-end rot, cracking, and disease
