Suståne 8-4-4 Natural Organic 45 Day Slow Release Fertilizer

Designed for Professional Nursery, Greenhouse and Landscape Applications

Description:

8-4-4 Container Media Grade (CMG) granules are ideal for use with plug production to provide uniform distribution of nutrients in blending organic potting soils and in low volume containers and tray mixes. When used in containers the nutrient release profile is 45 days (at 25°C / 70°F). Suståne 8-4-4 is composed of aerobically composted turkey litter, feather meal, and sulfate of potash. Suståne 8-4-4 All Natural is available in both fine and medium particle sizes.

Recommended Use:

Sustane 8-4-4 All Natural is high nitrogen, natural and organic fertilizer specifically designed for professional nursery, greenhouse, and landscape applications.  Suståne 8-4-4 is ideal for organic production of bedding and foliage crops, herbs, and vegetables including basil, cilantro, cucumbers, and tomatoes. Also excellent in hanging baskets and the production of annuals such as begonias, chrysanthemums, petunias, impatiens, and geraniums.

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%).

  • 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 from 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.
