The Science Behind It

How It Works

This balanced formula provides complete nutrition for blueberries, which have specific soil and nutrient requirements. The 10-10-10 ratio supplies all macronutrients in appropriate proportions for blueberry growth, flowering, and fruit production. Applied in spring and after harvest, nutrients support both current-year production and the development of next year's flower buds. The formula works within the acidic soil conditions blueberries require.

The Science

Blueberries have shallow, fibrous root systems without root hairs, limiting their nutrient absorption capacity. They evolved in acidic, nutrient-poor soils and are adapted to low-fertility conditions—heavy feeding can damage roots and reduce production. The balanced 10-10-10 ratio provides adequate but not excessive nutrition. Nitrogen supports leaf development and shoot growth. Phosphorus aids flower bud formation and root function. Potassium improves berry size, sugar content, and winter hardiness.

Nutrients Available 

10% Total Nitrogen – Supports shoot growth and leaf production. 10% Available Phosphate (P₂O₅) – Drives flower bud formation and root health. 10% Soluble Potash (K₂O) – Enhances berry size, flavor, and cold hardiness. Balanced nutrition for highbush, rabbiteye, and all blueberry varieties.

How to Apply

1-2 lbs/100 sq ft every 4-6 weeks. Severe deficiency: 2-3 lbs initially.

1

Action:

Survey garden bed and note deficiency symptoms. Map high-need zones.

Pro Tip:

Sandy areas and fruiting sections need more K than shaded areas.

Avoid:

Don't leave granules on surface in hot weather - damages plants.

2

Action:

Calculate 1-2 lbs per 100 sq ft. For 10x20 garden (200 sq ft), use 2-4 lbs.

Pro Tip:

Weigh fertilizer on kitchen scale. One cup 0-0-60 weighs ~0.5 lb.

Avoid:

Don't exceed 2 lbs per 100 sq ft per application. Split heavy doses.

3

Action

Broadcast granules evenly across soil surface. Work into top 2-3 inches with cultivator.

Pro Tip:

Sandy areas and fruiting sections need more K than shaded areas.

Avoid:

Don't spread on windy days - granules drift causing uneven application.

4

Action

Water thoroughly with 1-2 inches to dissolve granules and move K into root zone.

Pro Tip:

Incorporation prevents salt buildup and gets K to roots faster.

Avoid:

Don't leave granules on surface in hot weather - damages plants.
