FoxFarm Happy Frog Japanese Maple Fertilizer 4-3-4 | 4lb - OMRI Listed - (Case of 12)

Low-pH Formula for Japanese Maples and Other Acid-Preferring Trees

Japanese maples and a handful of other ornamentals thrive in a lower soil pH than most general garden fertilizers are built around, and feeding them with an all-purpose blend can leave that preference unaddressed over time. FoxFarm Happy Frog Japanese Maple 4-3-4 is a granular fertilizer formulated specifically for Japanese maples and other low-pH feeders, blending balanced nutrients with soil microorganisms.

The 4lb OMRI Listed bag, sold in a case of 12, suits nurseries and home gardeners who regularly fertilize Japanese maples, evergreens, and other acid-preferring ornamentals across multiple plantings.

Frequently Asked Questions

What plants does this fertilizer work best for?

It's formulated for Japanese maples, lilies, evergreens, hydrangeas, junipers, dogwoods, flowering ornamentals, and other plants that thrive in lower soil pH conditions. It isn't intended as a general-purpose garden fertilizer for the whole yard.

Is Happy Frog Japanese Maple fertilizer OMRI Listed?

Yes, it's OMRI Listed for use in organic production. That certification carries through regardless of whether it's applied to a single specimen tree or a full nursery row.

What does the 4-3-4 NPK ratio support?

The balanced nitrogen and potassium support foliage color, root development, and overall plant health without pushing excessive vegetative growth. It's a moderate ratio suited to established ornamentals rather than a heavy feeding formula.

How should I apply this fertilizer around a tree?

Apply around the tree's drip line, work it lightly into the soil surface, and water in thoroughly. Use at the start of the growing season and again mid-season if the tree needs it.

Does this fertilizer contain soil microorganisms?

Yes, it's formulated with microorganisms alongside the granular nutrient load, matching FoxFarm's broader Happy Frog approach of pairing soil biology with a moderate N-P-K ratio. Check the product label for the specific microbial breakdown.
