Old Cobblers Farm™ Wicked Organics Organic Herb Fertilizer
Grow more flavorful herbs with balanced organic nutrition. 4-3-4 NPK formula enhances essential oils while keeping growth steady. Application guide.
Old Cobblers Farm™ Wicked Organic Herb Fertilizer
This specially formulated organic herb fertilizer uses a balanced blend of plant and mineral-based ingredients to provide gentle, sustained nutrition tailored specifically for herb cultivation. The 4-3-4 NPK ratio was chosen because herbs respond best to moderate, balanced feeding rather than the high-nitrogen programs used for vegetables.
Herbs grown with excessive nitrogen produce larger leaves but with less concentrated essential oils, resulting in weaker flavor and fragrance. The moderate nitrogen in this formula supports healthy growth without the flavor-diluting effects of over-fertilization. The balanced potassium content actually enhances essential oil production, improving both the culinary and aromatic qualities of your herbs.
This fertilizer is ideal for both annual culinary herbs (basil, cilantro, dill) and perennial herbs (rosemary, thyme, oregano, sage), as well as medicinal herbs and fragrant ornamental herbs like lavender.

What Is It ?
Growing herbs requires a different nutritional approach than most garden vegetables. Too much nitrogen produces lush but bland foliage — the essential oils and flavors that make herbs worth growing become diluted. Too little nutrition, and plants are weak, small, and unproductive. Old Cobblers Farm™ Wicked Organics Herb Fertilizer strikes the perfect balance.
With a gentle, balanced NPK of 4-3-4, this OMRI-listed organic fertilizer provides just enough nitrogen for healthy leaf growth while the balanced phosphorus and potassium support root strength, flowering, and — most importantly — the concentrated production of essential oils that give herbs their flavor and fragrance.
Whether you’re growing culinary herbs like basil, oregano, and thyme in kitchen containers, medicinal herbs in garden beds, or fragrant lavender in the landscape, this fertilizer gives your herbs exactly what they need — nothing more, nothing less. The slow-release organic formula feeds gently for weeks without the burn risk of synthetic fertilizers.
When To Apply ?
For garden herb beds, broadcast 1-2 lbs per 100 sq ft and mix into the top 2-3 inches of soil. For containers and pots, mix 1-2 tablespoons per gallon of soil at planting. For established container herbs, top-dress with 1 tablespoon per 6-inch pot monthly. For perennial herb gardens, apply at the lower end of the rate range — perennial herbs generally need less feeding than annuals. Water in after application.
How to Apply ?
1.
Application Rate
Calculate rate — 1–2 lbs per 100 sq ft for garden beds. Herbs generally prefer lighter feeding.
2.
Container Rate

FAQs
1.
What is the best organic fertilizer for herbs?
The best organic herb fertilizer provides gentle, balanced nutrition that supports healthy growth without overstimulating herbs into producing bland, watered-down flavor. Herbs grown with excessive nitrogen lose their concentrated essential oils and aromatic compounds. A moderate organic formula delivers steady nutrition that keeps herbs productive while preserving the intense flavors and fragrances they are grown for. Old Cobblers Farm™ Wicked Organics Organic Herb Fertilizer is specifically formulated to grow flavorful, aromatic herbs using OMRI-Listed natural ingredients.
2.
How often should I fertilize herbs?
Fertilize herbs every 4–8 weeks during the active growing season, using a light hand. Most culinary herbs are naturally adapted to lean, well-drained soils and can actually decline in flavor quality when over-fertilized. Mediterranean herbs like rosemary, thyme, oregano, and lavender need the least feeding — once or twice per season is sufficient. Heavier feeders like basil, cilantro, parsley, and dill benefit from feeding every 4–6 weeks. Old Cobblers Farm™ Wicked Organics Organic Herb Fertilizer provides the gentle, measured nutrition herbs prefer.
3.
Does fertilizer affect herb flavor?
Yes, fertilization directly impacts herb flavor and aroma. Over-fertilizing with nitrogen causes herbs to produce rapid, lush growth with diluted essential oil concentrations — resulting in bland, flavorless leaves. Under-fertilizing stunts growth and reduces leaf production. The ideal approach is moderate, balanced organic feeding that supports healthy growth while allowing the plant to concentrate its aromatic compounds. Organic fertilizers tend to produce better-flavored herbs than synthetics. Old Cobblers Farm™ Wicked Organics Organic Herb Fertilizer is specifically designed to maximize flavor and aroma in culinary and medicinal herbs.
4.
What herbs can I fertilize with organic herb fertilizer?
Organic herb fertilizer works on all common culinary, medicinal, and ornamental herbs, including basil, cilantro, parsley, dill, chives, thyme, oregano, rosemary, sage, mint, tarragon, marjoram, lemon balm, lavender, chamomile, and echinacea. Both annual and perennial herbs benefit from gentle organic feeding. Adjust frequency based on the herb's natural feeding habits — Mediterranean species need less, while annual leafy herbs like basil respond to more frequent applications. Old Cobblers Farm™ Wicked Organics Organic Herb Fertilizer is versatile enough for dedicated herb gardens and mixed kitchen garden plantings.
5.
Can I use herb fertilizer on container herbs?
Yes, container herbs especially benefit from organic fertilizer because the limited soil volume depletes nutrients quickly. Apply 1 teaspoon per small pot or 1 tablespoon per large container every 4–6 weeks during the growing season. The slow-release organic ingredients provide sustained feeding between applications without the salt buildup that synthetic fertilizers can cause in containers. Ensure containers have good drainage and flush with plain water monthly to prevent any mineral accumulation. Old Cobblers Farm™ Wicked Organics Organic Herb Fertilizer is gentle and safe for windowsill, patio, and balcony herb containers.
6.
How much organic fertilizer for an herb garden?
For in-ground herb gardens, apply 2–3 pounds of organic herb fertilizer per 100 square feet, mixing into the top few inches of soil. For individual herb plants, use 1–2 teaspoons per plant depending on size. For raised bed herb gardens, use 1–2 pounds per 50 square feet. Remember that most herbs prefer lean conditions — less is more when fertilizing herbs. The gentle, slow-release nature of organic fertilizer makes it nearly impossible to over-apply at these rates. Old Cobblers Farm™ Wicked Organics Organic Herb Fertilizer delivers the right amount of nutrition for flavorful, productive herbs.
7
Is organic herb fertilizer OMRI-Listed?
Yes, Old Cobblers Farm™ Wicked Organics Organic Herb Fertilizer is OMRI-Listed for certified organic production. This is especially important for culinary herbs, which are consumed directly and benefit from being grown without synthetic chemicals. OMRI certification guarantees that all ingredients meet strict organic standards, giving herb growers confidence that their basil, cilantro, parsley, and other edible herbs are produced with only approved natural inputs. Old Cobblers Farm™ Wicked Organics carries the OMRI seal across all its organic fertilizer products.
