Foliar Fertilizers & Spray Supplies

Shop foliar fertilizers, soluble nutrients, biostimulants, and spray adjuvants for professional greenhouse, nursery, and crop-production programs. Compare nutrient sources and formulations to match your crop needs and product-label directions.

Calcium and micronutrient options

The selection includes Metalosate calcium, calcium-boron, multimineral, manganese, copper, and zinc products, along with Biomin calcium. Choose individual nutrients or blends based on the deficiency being addressed, product analysis, and labeled foliar use.

Soluble nutrients and foliar formulations

Browse magnesium sulfate and magnesium nitrate fertilizers, low-biuret urea, potassium acetate, and dedicated foliar formulations. Fulvic-acid and other biostimulant products provide additional options for programs where their labeled uses are appropriate. Not every product in this collection has the same application method or dilution rate; confirm suitability before mixing.

Spray adjuvants and application supplies

Aquatrols CapSil and Coco-Wet are application aids, not fertilizers. Where your spray product permits an adjuvant, choose a compatible formulation for the intended wetting or spreading function. Explore our spray adjuvants, surfactants, and wetting agents for related options.

Plan a compatible foliar program

• Follow crop-specific label directions, dilution rates, mixing order, and application restrictions.
• Check physical compatibility with a jar test before preparing a full tank.
• Assess plant tolerance on a small area before wider application.
• Use spray equipment only with formulations and application methods permitted by both the equipment instructions and product labels.

Foliar feeding complements root-zone nutrition. Browse our broader fertilizer selection for hydroponic, fertigation, and soil applications.
