Acid Mix (25 lb Bag)

The 25 lb bag of Down To Earth Acid Mix 4-3-6 is intended for larger berry rows, established landscapes, and repeated applications across multiple acid-loving plants. This bulk format provides the same granular formulation as the smaller packages while reducing the need to purchase and store several individual boxes.

• Best fit: Larger gardens, berry plantings, orchards, and landscape use.
• Plants: Blueberries, raspberries, azaleas, rhododendrons, hydrangeas, and evergreens.
• Analysis: 4-3-6 plus calcium, magnesium, sulfur, and humic acids.
• Application: Incorporate into planting soil or distribute around established plants and water thoroughly.

Measure your planting area before calculating the amount needed, follow the current 25 lb package label, and use a soil test when possible.

For complete designed analysis, ingredients, and general application guidance, see the 5 lb Acid Mix product guide.

How Acid Mix (25 lb Bag) fits a fertility plan

• Supports fertility programs for crops that perform best within a moderately acidic soil range.
• Helps gardeners make a measured pH-management choice when a current soil or water test shows that adjustment is appropriate.
• The package size and formulation shown in the title allow the product to be matched to containers, beds, orchards, or larger production areas.

Application guidance: Test first and adjust gradually. Soil texture, buffering capacity, irrigation-water alkalinity, and existing pH all affect the amount needed and the time required for change. Follow the label rate, mix or distribute evenly, water as directed, and retest before repeating an application. Do not use pH amendments as a substitute for crop-specific nutrition.
