9-18-9 Foliar Fertilizer

Targeted Foliar Nutrition for Healthier, Stronger Plants

Healthy plants depend on having the right nutrients available at the right time. Nature’s Pro 9-18-9 Foliar Fertilizer provides an efficient way to deliver essential nutrients directly to plant foliage, helping support plant health, growth, and vitality.

Formulated with exceptionally pure, highly refined ingredients, 9-18-9 is designed for rapid nutrient absorption. According to the product label, up to 94% of the applied nutrients can be absorbed and transported throughout the plant within 48 hours under suitable conditions.

Suitable for turf, trees, shrubs, flowers, vegetables, ornamentals, orchards, and agricultural crops, 9-18-9 offers a versatile approach to supplemental plant nutrition.

The Advantages of Foliar Feeding

Traditional soil-applied fertilizers must interact with soil conditions before nutrients become available to plants. Compaction, unfavorable pH, nutrient imbalances, and other soil factors can reduce nutrient availability and limit plant uptake.

Foliar fertilization provides an alternative pathway by applying nutrients directly to plant leaves, helping bypass some of the limitations associated with poor soil conditions.

Nature’s Pro 9-18-9 helps support plant nutrition by:

  • Delivering Nutrients Directly – Supplies essential nutrients to foliage for absorption through leaf surfaces.

  • Reducing Dependence on Soil Conditions – Provides supplemental nutrition when unfavorable soil conditions restrict nutrient availability.

  • Supporting Timely Nutrient Uptake – Helps address certain nutritional needs while longer-term soil improvements are being made.

  • Improving Application Efficiency – Allows nutrients to be applied as a fine spray rather than relying exclusively on soil injection or other application methods.

  • Supporting Plant Health Programs – Complements soil management practices and long-term plant health care strategies.

Efficient Nutrition with Practical Benefits

Foliar fertilizers are highly concentrated and are generally applied at relatively low volumes compared with many conventional soil fertilization methods.

Although specialized foliar formulations may have a higher cost per gallon, their efficient delivery methods and relatively low application volumes can make them a cost-effective option in certain plant health care programs.

Foliar feeding also offers practical advantages when treating plants growing in difficult or inaccessible soil conditions.

For arborists and plant health care professionals, this can mean fewer soil injection points, reduced application time, and greater flexibility when addressing plant nutritional needs.

Supporting Plants Throughout Their Growth Cycles

Different plants have different nutritional requirements depending on their species, growing conditions, and stage of development.

Foliar nutrition can be incorporated into programs designed to support:

  • Trees & Shrubs – Helps maintain plant vitality and provides supplemental nutrition when soil conditions are unfavorable.

  • Turf & Landscapes – Supports healthy growth and plant color as part of a balanced fertility program.

  • Flowers & Ornamentals – Provides supplemental nutrition during periods of active growth and flowering.

  • Vegetables & Fruit Crops – Supports plant nutrition during important developmental stages.

  • Agricultural Crops – Offers a flexible approach to supplemental nutrition across a wide variety of crop types.

Nature’s Pro offers several foliar fertilizer formulations to address different nutritional objectives, including 3-18-18, 7-21-7, 9-18-9, 10-10-10, and 18-3-3.

Application Rates & Considerations

Proper application timing, dilution, and water quality are important for effective foliar feeding.

Recommended Application Rates

Turf

Apply 5 gallons per acre, diluted 1:1, once per month during the growing season (6–8 applications).

Trees, Hedges & Shrubs

Mix 1 part 9-18-9 with 100 parts water.

  • For flowering ornamentals, apply before and after blooming.

  • For non-flowering ornamentals, apply after pruning.

  • For trees, the label identifies July and September application timing.

Vegetables & Gardens

Mix 1 part 9-18-9 with 50 parts water. Spray foliage lightly every two weeks once sufficient foliage has developed.

Important Application Guidelines

  • Apply when foliage is damp to encourage effective nutrient uptake.

  • Avoid spraying during the heat of the day.

  • Use hardness-corrected water of 5 grains (87 ppm) or less.

  • Consider plant species, growth stage, and environmental conditions when planning applications.

  • Incorporate soil testing and proper soil management into a comprehensive plant health care program.

Application recommendations may vary depending on plant type, growing conditions, and nutritional objectives.

Contact your Nature’s Pro representative for specific application recommendations. Always follow the current product label.

  • Apply as a fine, uniform mist to plant foliage.

  • Favor cooler periods of the day, such as early morning or late afternoon.

  • Avoid application during extreme heat or when plants are under severe moisture stress.

  • Consider plant species, growth stage, and environmental conditions when planning applications.

  • Follow product-specific directions and recommended application rates.

Application rates can vary considerably depending on the plant type, growing conditions, and nutritional objectives.

A Valuable Tool in Plant Health Care

Foliar fertilization can play an important role in a comprehensive Plant Health Care (PHC) program, particularly when plants are experiencing nutritional stress or growing in unfavorable soil conditions.

For arborists and PHC professionals, foliar feeding can provide a valuable short-term nutritional strategy while more extensive soil or tissue testing and diagnostic evaluations are completed.

Much like an initial supportive treatment, foliar feeding can help address certain immediate nutritional needs while the underlying causes of plant stress are investigated.

This approach allows professionals to supplement plant nutrition while identifying and correcting soil problems such as improper pH, compaction, limited biological activity, and insufficient organic matter.

Foliar feeding is not a replacement for healthy soil. Instead, it works alongside soil improvement practices to support both immediate plant nutrition and long-term plant health.
