Build Better Roots with Beneficial Fungi

Healthy plants start below ground.

Our Mycorrhizal Granules contain a broad-spectrum blend of endomycorrhizal and ectomycorrhizal fungi designed to establish beneficial relationships with the roots of compatible plants.

Once established, mycorrhizal fungi extend beyond the plant's own root system through networks of microscopic fungal hyphae. This expanded network can help plants access water and nutrients from a greater volume of soil, supporting stronger root development and overall plant health.

Use them when planting vegetables, fruit trees, perennials, landscape plants, seeds, bulbs, and other compatible plants.

🌱 What Are Mycorrhizal Fungi?

Mycorrhizae are beneficial fungi that form relationships with plant roots.

The plant provides the fungi with carbohydrates produced through photosynthesis. In exchange, the fungi extend their microscopic network into the surrounding soil, helping the plant access resources that its roots may otherwise have difficulty reaching.

It's one of nature's oldest partnerships — plants feeding fungi and fungi helping feed plants.

🌿 Why Use Mycorrhizal Granules?

Mycorrhizal fungi can help support:

  • More extensive root systems
  • Improved access to soil nutrients
  • Improved phosphorus uptake
  • Improved water uptake
  • Better establishment after planting or transplanting
  • Greater root-soil biological activity
  • More efficient use of available soil resources

🌳 Endo + Ecto for Broad-Spectrum Use

Different plants associate with different types of mycorrhizal fungi.

This formula contains both endomycorrhizal and ectomycorrhizal fungi, making it useful across a broad range of compatible garden and landscape plants.

🌱 Apply Where It Matters: The Roots

Mycorrhizal fungi need contact with living roots to establish.

For best results, apply the granules directly around seeds, young roots, root balls, or planting holes rather than simply broadcasting them over the soil surface.

Young plants and new transplants are particularly convenient times for inoculation because the fungi can establish as the root system develops.

🍅 Great For

  • Vegetable gardens
  • Fruit trees
  • Perennials
  • Trees and shrubs
  • Seeds and seedlings
  • Bulbs and tubers
  • New landscape installations
  • Bare-root plants
  • Garden beds
  • Sod and turf

🍄 What's Inside

Each 1 lb package contains a blend of volcanic rock, mycorrhizal propagules, and organic fertilizer.

The blend contains 12 endomycorrhizal and ectomycorrhizal fungi for broad-spectrum application.

📏 Application Rates

Plant Installations
Apply according to plant or container size, placing the granules where they will contact the root system.

Planting Beds
10 lb per 1,000 sq. ft.

Bare-Root Dip
1 lb per 1,000 seedlings or approximately 500 1-inch bare-root whips.

Seeding & Sodding
Apply 3 lb per 1,000 sq. ft. and incorporate into the soil.

Soil & Growing Media
Mix 2–5 lb per cubic yard.

Field Planting
Dust planting rows before or during planting so the granules are positioned near seeds, tubers, bulbs, or plant roots.

📦 What's Included

Net Weight: 1 lb

Contains: Endomycorrhizal and ectomycorrhizal fungi, volcanic mineral carrier, and organic fertilizer.

What are mycorrhizal granules?
Mycorrhizal granules contain beneficial fungi that can form symbiotic relationships with the roots of compatible plants, helping extend the effective reach of the root system into the surrounding soil.
What do mycorrhizal fungi do for plants?
They can help plants access water and nutrients from a greater volume of soil and support healthy root development and plant establishment.
What's the difference between endomycorrhizal and ectomycorrhizal fungi?
They are two major types of mycorrhizal fungi that associate with different groups of plants. This product contains both for broader application across compatible plant species.
When is the best time to apply mycorrhizal granules?
Planting and transplanting are excellent times because the granules can be placed directly in contact with developing roots.
Do the granules need to touch the roots?
Close root contact is important. Apply the product around seeds, roots, root balls, or inside planting holes so the fungi have an opportunity to colonize compatible roots.
Can I use this in my vegetable garden?
Yes. Many common garden vegetables form endomycorrhizal associations and can benefit from inoculation.
Can I use it with fruit trees?
Yes, provided the tree species forms a compatible mycorrhizal association. Apply the granules where they can contact the root system during planting.
Can I use it on established plants?
Yes, although getting the product into contact with actively growing roots is important. Application is generally easiest during planting or transplanting.
Does this replace fertilizer?
Not necessarily. Mycorrhizal fungi help plants access nutrients and water, but they do not create all of the nutrients plants require. Fertility needs still depend on the plant and soil conditions.
How much is included?
Each package contains 1 pound of mycorrhizal granules.
Can I use this when starting seeds?
Yes. The granules can be incorporated near seeds and developing roots so compatible plants can establish mycorrhizal associations as they grow.
Can I use it for sod or turf?
Yes. The listed application rate for seeding and sodding is 3 lb per 1,000 square feet, incorporated into the soil.
How much should I use in soil mixes?
The listed rate is 2–5 lb per cubic yard of soil or growing media.
Is more always better?
No. Apply according to the recommended rates and concentrate the product where it can contact compatible plant roots.
