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 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%).

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.
