Designed for Acid-Loving Plants
Many popular garden plants grow best in acidic soil, especially berries, flowering shrubs, and evergreen ornamentals. Down To Earth Acid Mix is formulated to provide the nutrients these plants need while helping maintain the lower pH conditions that support healthy growth, rich foliage color, stronger flowering, and improved fruiting.
Supports Better Blooms & Fruit Production
The 4-3-6 nutrient ratio provides a balanced supply of nitrogen for leafy growth, phosphorus for root and flower development, and potassium for plant strength, fruit quality, and overall vigor. This makes Acid Mix an excellent choice for blueberries, hydrangeas, azaleas, and other plants that need steady nutrition throughout the growing season.
Improves Soil Health Naturally
With humic acids from Leonardite and nutrient-rich organic ingredients, Acid Mix does more than feed plants. It helps improve soil structure, encourages microbial activity, and increases nutrient availability so plants can access what they need more efficiently.
When to Apply
Apply in early spring to wake plants up and support new growth. Reapply during the bloom period to encourage flowering and fruit production. A late fall application can help support root development and improve plant resilience before winter.
Organic Gardening Approved
Down To Earth Acid Mix is OMRI Listed for organic production, making it a trusted choice for organic gardeners, berry growers, landscape professionals, and anyone looking to feed acid-loving plants naturally.
