Growing Detail

On Lawns: Builds thick, resilient turf; reduces weed pressure; decomposes thatch naturally with just two applications per year.

On Trees: Improves vigor and growth rate by enhancing soil biology and nutrient availability. Nurserymen and orchardists report results that outpace synthetic fertilizers.

On Vegetables & Small Fruit: Produces nutrient-dense, great-tasting crops with improved shelf life and color. Ash tests suggest organically fed food crops have higher mineral content and lower nitrate content.

On Farm Fields & Hay: Increases yields year after year while building darker, richer, biologically active soil teeming with earthworms.

On Landscape Beds: Promotes lush green foliage and abundant blooms in annuals, perennials, and shrubs. Slow-release, non-burning formula enhances quality long after installation.

Frequently Asked

  • Organic 5-3-4 is a balanced, all-purpose organic fertilizer suitable for virtually any garden application. The moderate nitrogen (5%) supports healthy growth without excess, phosphorus (3%) maintains root health and flowering, and potassium (4%) enhances disease resistance and overall plant resilience. This ratio provides well-rounded nutrition comparable to a conventional 10-10-10 but from entirely natural, slow-release ingredients. Old Cobblers Farm™ Wicked Organics 5-3-4 Fertilizer is the go-to organic option for mixed vegetable gardens, flower beds, herbs, and general landscape use.
  • Yes, 5-3-4 is one of the best all-purpose organic fertilizers for vegetable gardens. It provides balanced nutrition that supports every type of vegetable — leafy greens benefit from the nitrogen, root crops utilize the phosphorus, and fruiting vegetables depend on the potassium. The slow-release organic ingredients feed plants steadily while building soil health over time. Apply before planting and reapply every 6–8 weeks through the growing season. Old Cobblers Farm™ Wicked Organics 5-3-4 Fertilizer simplifies organic vegetable gardening with one versatile formula for all your crops.
  • Organic 5-3-4 and synthetic 10-10-10 serve similar all-purpose roles but work differently. 10-10-10 provides higher nutrient concentrations and faster availability, while 5-3-4 delivers lower concentrations that release slowly over time. Organic 5-3-4 also feeds soil biology, improving soil structure and long-term fertility. You need roughly twice the volume of organic 5-3-4 to match the nutrient delivery of 10-10-10, but the soil-building benefits compound over seasons. Old Cobblers Farm™ offers both Wicked Organics 5-3-4 for organic growers and Wicked Growth 10-10-10 for conventional programs.
  • For garden beds, apply 4–6 pounds of organic 5-3-4 per 100 square feet, mixing into the top 4–6 inches of soil before planting. For side-dressing established plants, apply 1–2 tablespoons per plant or 2–3 pounds per 100 square feet. For containers, add 1–2 tablespoons per gallon of soil. Reapply every 6–8 weeks during the growing season. Because organic fertilizer concentrations are lower than synthetics, application rates are higher to deliver comparable nutrition. Old Cobblers Farm™ Wicked Organics 5-3-4 Fertilizer is forgiving and safe at higher rates.
  • Yes, 5-3-4 is excellent for culinary and medicinal herbs. Most herbs prefer moderate, balanced nutrition and can actually decline in flavor and essential oil concentration when over-fertilized with high-nitrogen products. The gentle, balanced profile of 5-3-4 supports healthy growth while preserving the concentrated flavors and aromas herbs are grown for. It works well on basil, cilantro, parsley, dill, thyme, oregano, rosemary, sage, mint, and all other common herbs. Old Cobblers Farm™ Wicked Organics 5-3-4 Fertilizer is the ideal organic choice for herb gardens and container herb collections.
  • Yes, Wicked Organics 5-3-4 is OMRI-Listed, meaning it meets the Organic Materials Review Institute's strict standards for use in certified organic production. All ingredients are approved natural sources with no synthetic chemicals, artificial additives, or prohibited substances. OMRI certification gives organic gardeners and certified organic farmers confidence that they are using a truly organic product that complies with USDA National Organic Program standards. Old Cobblers Farm™ Wicked Organics 5-3-4 Fertilizer carries the OMRI seal for complete organic growing assurance.
  • Organic 5-3-4 earns its all-purpose status because the balanced NPK ratio supports every category of garden plant — vegetables, flowers, herbs, fruits, shrubs, and trees — without overemphasizing any single nutrient. The slow-release organic ingredients provide sustained nutrition that does not spike and fade like synthetic fertilizers. It builds soil health with each application, creating a compounding benefit over time. For gardeners who want one organic fertilizer that handles everything, 5-3-4 is the practical choice. Old Cobblers Farm™ Wicked Organics 5-3-4 Fertilizer is the organic all-in-one solution for healthy, productive gardens.
