Grow More® Soil Acidifier 30-10-10 — 1.5 lb Jar

Dual-Action Formula That Fertilizes and Lowers Soil pH at the Same Time

Feeding an acid-loving plant in alkaline soil without also managing pH is treating half the problem — micronutrients like iron and manganese stay locked out even with perfect fertilization. Grow More Soil Acidifier 30-10-10 addresses both in one application, combining a high-nitrogen 30-10-10 NPK formula with acidifying chemistry that actively lowers alkaline soil pH toward the range roses, azaleas, camellias, rhododendrons, hydrangeas, and blueberries prefer.

In regions where soil or irrigation-water alkalinity is a persistent challenge, this dual-action approach means correct pH management happens with every routine feeding rather than as a separate, easily-forgotten step.

Key Features & Benefits

• Dual Action: Delivers a complete 30-10-10 nutrient application while simultaneously working to lower soil pH.
• 30% Nitrogen for Vigorous Growth: High nitrogen drives strong vegetative growth, chlorophyll production, and shoot development.
• Lowers Alkaline Soil pH: Acidifying chemistry reduces soil pH toward the slightly acidic 5.5 to 6.5 range many specialty crops prefer.
• Improves Micronutrient Availability: Reducing pH unlocks iron, manganese, and zinc that go unavailable at high pH.
• Water-Soluble Convenience: Dissolves for root drench or soil treatment application via hand watering or drip irrigation.

Who Should Use This

Gardeners and cultivators growing acid-loving plants in alkaline soils or hard-water regions are the direct fit, along with indoor and greenhouse growers managing media that drifts alkaline over time. Not recommended for hydroponic systems or environments where root-zone acidification isn't desired.

Frequently Asked Questions

What causes alkaline soil and why is it a problem for certain plants?

Alkaline soil results from high calcium carbonate content or irrigation with high-pH water. Acid-preferring species evolved enzyme systems optimized for acidic pH, and in alkaline conditions, iron and manganese become chemically unavailable even when physically present in the soil.

How quickly does the Soil Acidifier lower pH?

Speed depends on soil buffering capacity, application rate, and existing alkalinity. Sandy soils with low buffering capacity respond faster, while heavy clay or highly calcareous soils need repeated applications over time to achieve and hold a lower pH.

Can I use this product on vegetables and edibles?

Yes, the 30-10-10 formula is a general-purpose fertilizer suited to a wide range of vegetables and edible crops, particularly those preferring a slightly acidic soil. Follow label rate guidelines for edible crop applications.

Will Soil Acidifier affect soil microbes?

Moderate pH reduction, moving from 7.5-plus down into the 6.0 to 6.5 range, generally improves microbial diversity since many beneficial soil organisms are most active in slightly acidic conditions. Avoid over-acidifying below 5.5, which can inhibit both roots and beneficial microbes.
