Sustainable landscaping is about natural-based, functional, and ecologically minded practices that actively help professional growers and communities. Since 1988 Suståne Natural Fertilizer is proud to be a part of the global movement toward building a more sustainable world. Better land management, protection of our waters, saving and rebuilding soils, improving lawns and landscape beds, serving landscape contractors and homeowners alike – all through the utilization of recycled, renewable natural resources. Suståne’s granulated, organic and natural base slow release fertilizers are produced in Minnesota and available through local distributors.

Suståne introduces a broad range of organic fertilizers designed and developed for the professional landscape and architectural applications. Suståne products are used for commercial and institutional projects, green roof fertilization, native flowers and prairie restoration. Suståne produces predictable results, dependable performance and high quality plants with low environmental impact, non toxic, safe for people, plants, animals and the environment.

Low Environmental Impact:

  • Safe for people, animals and the environment.
  • Organic nitrogen is released slowly to the plant, minimizing loss to the environment.
  • The longer N-release reduces energy requirements and labor vs. more applications of water-soluble synthetic fertilizers.
  • Suståne stimulates the natural cycling of nutrients and carbon between soil and plant.
  • Suståne reduces need for pesticides. Less pesticides reduce maintenance costs.
  • Suståne is biologically stable, pathogen free, will not reheat, will not combust, does not attract wild or domestic animals, birds or insects to establishment sites.

Low Carbon Footprint:

  • Made from natural renewable agricultural resources, has a low carbon & green house gasses (GHG) footprint.
  • Suståne complies with regulatory mandate and exceeds most health & safety standards.
  • The Suståne process avoids the generation of more significant green house gasses such as methane and nitrous oxide.
  • With Suståne the energy required to transport is reduce 4:1 per kg. vs. wet compost.
  • Granulation simplifies handling allowing more accurate application of fertilizer. The product stays where it was applied.

Applications:

  • Seed Starting & Bedding Plants: Mix Suståne with soil substrate prior to planting.
  • Flower Beds & General Landscaping: Broadcast and incorporate Suståne in the spring and again every 45 days.
  • Potted Plant & Container Plants: Mix Suståne with soil substrate prior to transplanting.
  • Trees and Shrubs: For new planting, place Sustane in hole before planting and lightly incorporate. For established trees and shrubs, broadcast Suståne at the base of the plant in the spring and again in the fall. Application rates are based on the individual plants canopy spread along with the fertilizer analysis.

Suståne® PumicePlus

An engineered structural growing media and soil conditioner

Description:

PumicePlus is an engineered soil developed in coordination with a green roof expert with installations across North America and around the world. PumicePlus is composed of two parts, an inert material that ensures structural integrity, and carefully selected growing inputs which provide the foundation for healthy root growth. It aids in the establishment and long-term health of plants when used in green roofs, green walls, containers, landscaped spaces, or specialized soil projects. 


 

A Uniquely Formulated Granular pumicproductimage1

PumicePlus combines a granular mix of premium ingredients including Suståne Aerobically Composted Turkey Litter, Coconut Coir, Feathermeal, (UK/EU: Non-GMO Corn Gluten Meal), Langbeinite, Worm Castings, Humates, Seaweed, and Mycorrhizal fungi. Each ingredient has been micronized and combined into every individual granule to create a supercharged grow media that is rich in biostimulants and microbiology essential to healthy plant growth. 

Benefits of Suståne PumicePlus

  • Reduces soil compaction and loosens heavy soils, increasing aeration and drainage. This allows oxygen to enter the root system and carbon dioxide respirated by the roots to exit. The exchange of gases in the root zone is critical to having healthy and vibrant plants. 

  • Contains millions of micropores that allow it to store water, nutrients, and microbiology and releases them slowly back into the soil. This creates a water and nutrient bank that will prevent runoff and save valuable resources for when they are needed most. 

  • Supplies humic acid: Humates increase nutrient uptake, drought tolerance, promote beneficial microbial activity, and buffer soils.

  • Contains an optimal balance of primary, secondary, and micro-nutrients needed for optimal plant growth.

  • PumicePlus is pH Neutral and improves buffering against changes in soil pH. 

  • Increases the soil’s cation exchange capacity and improves soil structure, porosity, and stability leading to greater root development.

  • Safe for plants, people, and the environment. As a naturally occurring, and easily accessible material, pumice has a 1300% smaller carbon footprint than other mined soil media. No water, no heating, and no chemicals.

 

Why Pumice Stone?

Pumice (right) is the cornerstone component of PumicePlus and provides many advantages: Pumice

It is highly porous and holds both water and air— critical to well-conditioned, aerated soils. 

Pumice has a naturally lightweight structure which provides an excellent platform for microbial colonization. This creates an ideal balance between drainability, moisture retention and gas exchange in the root zone. 

Pumice has a rough surface texture which provides the benefit of creating stable installations that might otherwise be prone to compacting, contracting, shifting or swelling - keeping landscapes true to form.

Always Safe for Plants, People, and the Environment

  • Pumice has a 1300% smaller carbon footprint than other mined soil media.
  • Manufactured by Suståne in the USA at an EPA permitted facility.
  • Pathogen and weed-free, no blood or bone products. Allowed for export to over 60 countries worldwide.
  • Aerobic composting eliminates animal and rodent attraction to the application site.
  • Contains naturally occurring beneficial bacteria and fungi that are necessary to begin the nutrient life cycle in poor soil.
  • Suståne is fully composted eliminating the need for sterilization, permitting a healthy environment for beneficial microbial populations.
