Down To Earth All Natural Fertilizers Organic Acid Mix 4-3-6, 1 lb — Slow‑Release Fertilizer for Acid‑Loving Plants

Down To Earth All Natural Fertilizers Organic Acid Mix (4-3-6) is a slow‑release, low‑pH fertilizer formulated to feed acid‑loving plants like azaleas, rhododendrons, camellias, blueberries and evergreens.

This one‑pound bag provides a measured, organic nutrient blend designed to support vigorous foliage, abundant blooms and better fruiting for plants that prefer acidic soils. The formula releases nutrients gradually, helping maintain steady growth without frequent reapplications, and it can be used for spring feeding, bloom‑time boosts, and fall root development. It also aids in creating a more acidic root zone, which improves nutrient availability for ericaceous and other acid‑loving species.

How does this Acid Mix help acid‑loving plants perform better?

Organic Acid Mix supplies a balanced ratio of nitrogen, phosphorus and potassium (4-3-6) alongside organic ingredients that condition the root zone. By supporting an acidic environment, it helps these species access iron, manganese and other micronutrients more efficiently.

• Formulated specifically for azaleas, rhododendrons, camellias, hydrangeas, blueberries and similar plants
• Encourages lush foliage and stronger blooms when applied at key growth stages
• Helps maintain lower soil pH around the root zone to improve nutrient uptake

When and how should I apply this fertilizer for best results?

Apply in early spring to support new vegetative growth and again at the start of bloom to feed flowers and developing fruit. A fall application promotes root growth and resilience going into winter; always follow label rates and avoid overapplication.

• Spring application for active growth; repeat at first bloom for flowering plants
• Fall feeding supports root development and hardiness before dormancy
• Use the product instructions for per‑plant or per‑square‑foot rates to prevent excess nutrient buildup

What makes this a good slow‑release organic option compared to synthetic fertilizers?

The slow‑release nature comes from organic carriers and nutrient sources that break down gradually, supplying steady nutrition and reducing fertilizer burn risk. This approach supports beneficial soil life and long‑term soil structure while providing ongoing nutrient availability.

• Steady nutrient release lowers the need for frequent reapplication
• Organic composition supports soil biology and structure
• Less risk of rapid salinity spikes or root damage common with some synthetic salts

Can this product help adjust soil pH, and how should I monitor it?

While Acid Mix is formulated to favor acid‑loving plants and can help maintain an acidic root zone, it’s not a replacement for major soil amendments if your garden pH is far from the target. Test soil pH periodically and use complementary products like elemental sulfur if long‑term pH lowering is needed.

• Helps sustain a more acidic microenvironment at the root level
• Periodic soil pH testing ensures you stay within the optimal range for specific plants
• Combine with cultural practices (mulch, acidifying amendments) for lasting pH control

Who is this for: Gardeners growing ericaceous and other acid‑loving plants who want an all‑natural, slow‑release fertilizer to promote steady growth, better blooms and improved fruit set. Ideal for home gardeners with azaleas, rhododendrons, camellias, hydrangeas, blueberries, raspberries, strawberries, potatoes and acid‑preferring evergreens seeking an organic feeding schedule without frequent reapplication.
