  • Readily available source of calcium, iron, magnesium, and potassium
  • Increases phosphorous availability
  • Enhances root structure and improves soil fertility
  • Will not "burn" plants or seedlings
  • Made in the USA

Soil Amendment

Add glacial rock dust to vegetable gardens, flower beds, containers, on lawns, and around trees. It improves soil structure, moisture retention, nutrient availability, microbial action and also raises pH in acidic soils.

Source of Minerals

Glacial rock dust is an abundant natural mineral source. Both plants and animals benefit from a regular supply of minerals, which are best transferred to the human body through foods grown in mineral-rich soils. Add glacial rock dust to your vegetable gardens to increase mineral content in harvested fruits and vegetables.

How To Use:

Glacial rock dust should be applied to gardens every spring, and seasonally for intensive growing. Gently dig into the soil surface. Apply 25 lbs per 100 sq. ft.

Transplanting and pre-mixing into soil: Add 8 tablespoons per 1 gallon of soil, and thoroughly mix into soil prior to transplanting.

Top dressing: For raised beds, potted plants and hanging baskets, gently till glacial rock dust into the surface of the soil. Use 4 tablespoons per 1 gallon of soil. Apply up to once per month.

Composting: Mix liberally into your compost as a microbial enhancer. Increases nutrients in finished compost.
