Use and Application Rates:

Application rates of Suståne water-dispersible fertilizers should be made based according to the crop's nutritional needs and tolerance for salt stress. This material should be diluted in water and mixed well prior to application. For best results, add package contents to fresh water in clean containers with mixing as described below (see reverse).

The preparation of a homogenous solution is critical to successful fertigation. It is highly recommended that growers prepare a base concentrate of Sustane’s Flourish WDF in a watering can or bucket of water before dispensing to ensure proper application rate. When diluted correctly, this product can be applied to plants with a watering can. Due to organic compost particulates, Flourish WDF is not compatible with commercial sprayers or fertigation systems.

Fertigation Rates and Application:

Prepare a base concentrate by thoroughly mixing up to 2 tablespoons (approximately 15 g) per gallon of water (of Suståne Flourish WDF per 1 gallon of water (or 4 g per liter). Fertilizer solutions can be applied every one to two weeks depending on crop demand and growing conditions.

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.
  • Monitor electrical conductivity (EC) of container substrate throughout the production cycle.
  • Adjust application rate as needed.
