Our take on the FoxFarm Happy Frog Fruit & Flower Fertilizer

FoxFarm Happy Frog Fruit & Flower is a granular organic fertilizer with an NPK of 4-9-3, built around the high phosphorus that fruiting and flowering plants need. It also carries nitrogen for late-season growth and includes mycorrhizal fungi, which the maker says can improve root efficiency and nutrient and water uptake. It is OMRI listed and registered as a CDFA organic input material, so it fits certified organic gardens. It suits gardeners feeding tomatoes, peppers, roses and other bloomers, but its 3.1 rating from 63 buyers shows a divided reception, so expect to read the complaints before committing a whole bed to it.
