FoxFarm Happy Frog Fruit & Flower 4-9-3 | 4lb - OMRI Listed

Phosphorus-Forward Granular Feed for Fruiting and Flowering Plants, 4lb

Plants moving from vegetative growth into flowering or fruit set need a jump in phosphorus that a general-purpose fertilizer doesn't always deliver, and nitrogen alone will keep pushing leaf growth at the expense of blossoms and fruit. FoxFarm Happy Frog Fruit & Flower 4-9-3 is a granular fertilizer built around that transition, with mycorrhizal fungi included to support root efficiency alongside the nutrient load.

The 4lb OMRI Listed bag is sized for home gardens and smaller plantings, giving flowering and fruiting plants a season's worth of phosphorus-forward feeding without a bulk-size commitment.

Key Features & Benefits

• OMRI Listed — meets the standard for use in certified organic production (4lb size).
• 4-9-3 NPK ratio — the elevated phosphorus at 9% targets fruit and flower development specifically.
• Nitrogen for continued growth — keeps the plant developing through to the end of the season rather than stalling once flowering starts.
• Mycorrhizal fungi included — supports root efficiency, which can help the plant take up the nutrients already in the soil.
• Granular, easy to apply — worked in around the base of plants or incorporated into garden beds at planting.

Who Should Use Fruit & Flower Fertilizer

Gardeners and growers with flowering ornamentals, fruiting vegetables, or any plant moving from vegetative growth into its reproductive stage are the fit for Fruit & Flower, particularly where an elevated phosphorus level is the priority over continued leaf growth.

About Fox Farms

FoxFarm's Happy Frog line, formulated in Humboldt County, California since the company's 1984 founding, builds its granular fertilizers around soil microbes and mycorrhizal fungi rather than synthetic salts alone.

Frequently Asked Questions

What does the 4-9-3 ratio in Fruit & Flower actually support?

The elevated phosphorus at 9% is aimed at fruit and flower development, while the nitrogen at 4% keeps the plant growing through the rest of the season rather than stopping once blooms appear. Together they cover both continued growth and the reproductive push.

Is Happy Frog Fruit & Flower OMRI Listed?

Yes, the 4lb size is OMRI Listed, meeting the standard for certified organic production. That covers flowering ornamentals and fruiting vegetables grown under an organic-only program.

When should I start applying Fruit & Flower fertilizer?

Apply at the onset of flowering or fruiting and continue through the season as directed on the label. Starting earlier than that isn't necessary since the formula is built around the reproductive stage rather than early vegetative growth.

What does the mycorrhizal fungi in this fertilizer actually do?

Mycorrhizal fungi form a relationship with plant roots that can extend their effective reach for water and nutrients already present in the soil. It's included here as a root-efficiency booster alongside the granular nutrient load rather than as the primary feeding mechanism.

What kinds of plants is this fertilizer meant for?

It's built for flowering ornamentals, fruiting vegetables, and any plant in the transition from vegetative growth to reproductive growth where extra phosphorus support helps. It isn't limited to one specific crop type.
