A phosphorus-forward organic feed built for tomatoes and peppers, its 4-6-3 analysis supporting flowering and fruit set while TruBiotic mycorrhizae help roots establish; the people- and pet-safe ingredients suit containers. Live with tradeoffs: the fishmeal blend smells pungent and can attract animals so water it in, it costs more than synthetics, and it is slow-acting.
Pros
- Higher phosphorus (6) supports flowering and fruit set on tomatoes and peppers
- People- and pet-safe organic ingredients, no synthetic chemicals or GMO chicken manure
- TruBiotic mycorrhizae help roots establish and improve drought tolerance
Cons
- Pungent fishmeal/organic smell can attract animals; water it in well
- Premium price per pound compared with synthetic tomato foods
- Slow-acting; results build over weeks, so apply early and follow label rates

Frequently Asked Questions
- Why does a tomato fertilizer have higher phosphorus?
- Phosphorus supports flowering and fruit set, which is what you want from tomatoes and peppers rather than more leaf growth. The 4-6-3 ratio is built around that priority.
- Will organic fertilizer attract animals?
- It can. The pungent fishmeal smell draws digging pets and wildlife, so water it in well after applying rather than leaving granules on the surface.
- What do the mycorrhizae actually do?
- TruBiotic mycorrhizae colonize the root zone and help roots take up water and nutrients, which also improves drought tolerance. It is slow-acting overall, so apply early and follow label rates rather than expecting a quick green-up.
