Cohasset Croptopper 3-2-1

Throw-and-Go Fertilizer for Fruits and Vegetables


Budget-friendly with more bang for your buck than any other fertilizer of this kind, the Cohasset Croptopper 3-2-1 was created to meet the needs of our local large-scale gardeners looking for an effective, affordable organic fertilizer. When you have a commercially sized field or garden to care for, you’ll need a fertilizer that delivers easy nutrition at a fair and reasonable price, so you’ll appreciate this fertilizer is half the price of other Kinney fertilizers. Great deal! We learned our large-scale crop customers needed an easy way to disperse the fertilizer across big plots of land, so we designed it as a “throw and grow” granulated formula, easy to topdress and water. Used in conjunction with a compost tea program, the Cohasset Crotopper 3-2-1 is just as plant-friendly as the rest of our fertilizers, supporting a sustainable soil food web and vibrant growth with a large number of micronutrients and ingredients.

Special Features:
Fantastic value! Bio char and humic acid are unique ingredients for a product at this price point! Most other organic fertilizers at this price will not contain such high-quality ingredients.

Good for:
All types of gardening, particularly large-scale hemp fields, rose gardens, or other commercial plantings.

Ideal Consumer:
The Cohasset Croptopper is an excellent choice for economical gardeners, those on a budget, or for gardeners who prefer to apply a large amount of fertilizer on a regular basis—without incurring exceedingly high costs. In addition, the inclusion of gypsum helps to loosen the soil, making this an excellent choice for gardeners working with compacted, heavy, or poor soils.

Growing Location:
Good for greenhouse or outdoor growing locations, especially large scale or commercial gardens.

How to Use:

For healthy plants, topdress with Kinney’s Cohasset Croptopper every one to two weeks.
Water thoroughly after every application.
Use in conjunction with a Compost Tea program.
