Best Uses / Plant Types

This fertilizer is made for plants that thrive in acidic soils, including:

Azaleas • Blueberries • Chrysanthemums • Ferns • Gardenias • Rhododendrons • Heaths & Heathers • Huckleberries • Hydrangeas • Marigolds • Mountain Laurels • Oaks • Pachysandras • Lupine • Raspberries • Yews • Flax • Other acid loving plants

Benefits & Performance

Promotes vibrant blooms and deep green foliage thanks to its well-rounded N-P-K balance.

Enhances root development and frost hardiness when applied in fall, with spring feedings prompting larger leaf surface and more blossoms.

Improves soil health: organic matter helps retain moisture, supports beneficial microbes, and ensures better nutrient uptake.

Helps alleviate problems associated with neutral to alkaline soils (yellowing, stunted growth) by supplying nutrients that are more available in acidic conditions.

How & When to Apply

Timing: Best applied in spring and fall. If you can only feed once, fall is preferred to support root health and winter hardiness.

Application rate: Spread 1 pound per 2 feet of crown diameter beneath the plant’s drip line. Feeder roots often extend past the branches—cover the whole root area.

Mulch tip: You can apply over mulch, but for faster results, temporarily remove mulch, broadcast fertilizer, water, then replace mulch.

This product helps growers reduce leaf yellowing, improve bloom size, and build a soil environment where roots can thrive.
