Tomato-Specific Organic Formula
Best Organic Tomato-Only Fertilizer (5-3-4): Purpose-Built for Tomato Biology — From Transplant to Final Harvest Buy on Old Cobblers Farm
This isn't a general garden formula with "tomato" on the label — it's formulated around how tomatoes actually grow. Higher potassium relative to phosphorus supports fruit sizing and flavor development, while slow-release protein meals feed vines steadily through the long fruiting season.

Tomato-Specific Formulation
Labeled and programmed specifically for tomato growing. Per-plant rates, timing, and application methods are dialed in for tomato biology — no guesswork required.
4% Potassium for Flavor & Firmness
Potassium from sulfate of potash drives the sugar accumulation and acid balance that create complex tomato flavor. More K = sweeter, firmer, better-tasting fruit.
Season-Long Slow Release
Protein meals release nitrogen through microbial activity over weeks — matching tomato nutrient demand from vegetative growth through the long fruiting season.
Per-Plant Dosing Program
1–2 tbsp in the planting hole at transplant, then 2–3 oz side-dressed per plant monthly. Simple, repeatable program for any number of tomato plants.
Calcium from Natural Sources
Natural calcium in the formula helps prevent blossom end rot — the #1 tomato growing problem caused by calcium deficiency during rapid fruit development.
Builds Soil for Next Season
Every application feeds soil biology. By season's end, your tomato bed has more microbial diversity, better structure, and higher organic matter than when you started.
All Tomato Types & Setups
Beefsteak, cherry, roma, heirloom, grape — determinate or indeterminate. Works in beds, raised beds, containers, grow bags, and high tunnels.
