Suståne 4-6-4 is a natural organic starter and maintenance fertilizer. Suståne 4-6-4 works by replenishing the soil with a rich supply of humus (stabilized organic matter) and the essential nutrients required for sound and long-term fertility programs. Suståne 4-6-4 provides a combination of slow release nutrients and organic substances. Suståne replenishes the soil with a rich supply of humus (stabilized organic matter) and all of the essential nutrients required for quality growth. Derived from biologically stable compost plus natural potash and feathermeal. 4-6-4 All Natural Fertilizer promotes a rapid rate of vegetative establishment. Quick ground cover minimizes soil erosion and the need for repairs or re-seeding.

Landscapers' Choice: Professional landscapers have increasingly turned to Suståne 4-6-4 for use on high maintenance turf and landscaped environments. While synthetic fertilizers supply plant growth nutrients, they do not supply the organic matter required to maintain quality growth. Using fully composted natural fertilizers increases the levels of beneficial microbial activity, which in turn convert nutrients into plant available forms.

Incorporating into Potting Soil Mixes and other Container Substrates: Suståne 4-6-4 provides a constant release of nutrients when used with container substrates with an average temperature of 70oF / 21oC. When determining application rates consider all cultural practices including irrigation, container substrate physical characteristics and growing environment. Container Mix Application Rates:
|Container Mix Rates by Volume|
|lb. per cubic yard||kg per cubic meter|
Low Rate: Recommended for use on salt sensitive species; when concurrent with liquid feed; with production systems utilizing low leaching fractions (less than 10%); and when applied to heavy potting substrates (total porosity less than 65%).
Medium Rate: Recommended for use on medium feeding species; on most nursery stock and foliage plants; and when liquid feed is not performed concurrently.
High Rate: Recommended for use on heavy feeding species; with production systems utilizing high leaching fractions (greater than 20%); and when applied to light, porous substrates (total porosity greater than 80%). Bulk Density of Suståne 4-6-4:
|Rounded Measure (Volume)||Grams (weight)|
|Teaspoon (tsp)||Tablespoon (Tbsp.)||1 oz.||1/4 cup||1/2 cup||1 cup|

- These rates are intended as guidelines. Suståne encourages a trial prior to changing any fertilizer program.
- Do not steam sterilize container mix after fertilizer has been incorporated.
- Do not store container mix more than two weeks after incorporating fertilizer. Plant material can be damaged by salt accumulation.
- Monitor electrical conductivity (EC) of container substrate throughout the production cycle.
- If the mix is stored longer than two weeks, leaching container mix may be required to remove accumulated salts.
- Adjust application rate as needed.
