We love a good fertilizer, and this is one of our favorites. Perfect Blend Organic 6-3-3 fertilizer uses a proprietary process to create Complex Nutrition-Enabling Fertilizer (CNEF™) for a product that feeds plants and soil microbes simultaneously.

Each ingredient begins with a three-step quality assurance process to guarantee no weed seeds, pathogens, insect eggs, or insect casements are included in the final fertilizer. The homogeneous granular blend helps maintain a balanced pH with a formulation between 6.0 and 6.1 while promoting the rapid growth of soil microbes. 

Perfect Blend Organic 6-3-3 fertilizer features a primary 6-3-3 blend of nitrogen, phosphorus, and potassium with added secondary nutrients, including sulfur, calcium, and magnesium, as well as trace minerals, amino acids, and vitamins. 

This fertilizer is approved for certified organic crops and is an excellent option for turfgrass and other lawns and landscapes. You can also apply it to small gardens, ornamentals, raised beds, as potting soil, for transplants, and as a top dress.

No matter what you're growing, Perfect Blend Organic 6-3-3 fertilizer is a great tool to make your plants the best of the best.

    Application Rates

    Small Garden - Vegetables:
    Apply 2 lbs. along the bottom of a 24-foot section of the seed furrow, then cover the fertilizer with a thin layer of soil. Place your seeds on this soil layer, then cover the seeds with an additional layer of soil to the depth recommended on the seed package. For hill plants such as squash and potatoes, place one cup in the bottom and sides of the planting hole, followed by a layer of soil, then the seeds. Cover the seeds with ground-level soil and then water. For legumes, such as beans and peas, less nitrogen is required. Put half as much Perfect Blend, or one cup every 50 feet, for best results. During the growing season, apply an additional 2 lbs. every 50 feet after your plant's bloom. Work these plant nutrients into the soil around the plant root zone. A good time to do this is when weeding or hilling up your plants. Always water in newly applied fertilizer. 

    Bulk Applications:
    Apply 833 lbs. of fertilizer for every 50 lbs. of nitrogen required.  Apply 1666 lbs. of fertilizer for every 100 lbs. of nitrogen required. Apply 3332 lbs. of fertilizer for every 200 lbs. of nitrogen required. Fertilizer is most efficient if incorporated into the soil immediately after application 2” – 4”.

    Established Turf Grass:
    Apply as a top dressing for fairways, rough lawns, greens, landscapes, or any established grass. Apply 8.33 lbs. to 16.66 lbs. per 1,000 square feet for the application of 0.5 lb. to 1 lb. of actual nitrogen per 1,000 square feet. The maximum value of these fertilizers is obtained when applied during aeration.

    Starter or Grow-Ins:
    Apply 16.66 lbs. of fertilizer per 1,000 sq. ft. for 1 lb. of nitrogen. Till or rake into the top 2” – 4” after surface spreading.

    • 1 Cup = 1/2 Pound – 3 Cups = 1.5 Pound 

    Ornamentals and Raised Beds:
    Apply 1 lb. (Approximately 2 cups) per 25 sq. ft. Work into the soil 2” – 4” before placing flowers or ornamentals. Repeat application when buds bloom and in the late fall before frost.

    For Two Gallon pots, use 1 cup, Five Gallon pots use 2 cups, Fifteen Gallon pots use 4 cups. For a 24" Root Ball, use 6 cups. A 36" Root Ball use 24 cups, and A 48” Root Ball use 30 cups.

    Base Potting Soil:
    Mix 1/2 - 3 Cups (.25 – 1.5 Pounds) per cubic foot of base potting soil.

    1 Tablespoon per inch of pot size. Apply as often as necessary.

    I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
