Flavor-First Organic Feeding

Slow biological release develops the complex sugars, organic acids, and flavor compounds that make organic tomatoes taste noticeably better than synthetically-fed fruit. Flavor starts in the soil.

🌱

Transplant-to-Harvest Program

1–2 tablespoons in the planting hole at transplant, then 2–3 oz per plant monthly through harvest. A complete organic feeding program in one product.

🦠

Builds Living Soil

Protein meals feed the soil food web — bacteria, fungi, protozoa — that make nutrients available to roots naturally. Healthier soil = healthier plants = better tomatoes.

⏳

Biologically-Timed Release

Nutrients release when soil microbes are active — which is when plants are growing. Cold soil = slow release. Warm soil = faster release. Nature matches supply to demand.

🫑

All Garden Vegetables

Not just tomatoes — peppers, squash, cucumbers, eggplant, melons, and every garden vegetable thrives on this organic formula. One product for the entire organic garden.
