Peter's Special Plant Food

When people talk about "Peter's plant food," they are referring to numerous products from J.R. Peters, Inc. of Allentown, Pennsylvania, which manufactures water-soluble fertilizers for specialty agriculture, horticulture and retail markets. The sale of the original company --- and subsequent selling off of the Peters company name --- has caused no end of confusion for loyal customers trying to find their favorite Peters products. The company is family-owned once again, its product lines now sold under the Jack's Classic and Jack's Professional brand names.
  1. History

    • What is now J.R. Peters, Inc. designed, formulated and produced quality commercial fertilizers starting in 1947. Some products are favorites of home gardeners, but a large part of the business serves the specialty agriculture and horticulture --- commercial nursery --- markets. The reason you can't buy "Peters fertilizer" these days is that the retail name was sold some time ago, when Scotts --- as in Scotts Miracle-Gro --- owned the company. So when the Peters family bought the company back in 1997, according to Jack Peters' statement on the Jack's Classic website, a new name was needed.

    Jack's Classic

    • Available only in independent nurseries and garden centers and online, Jack's Classic products are formulated for home gardeners. An all-purpose 20-20-20 fertilizer leads the line, which also includes specialty fertilizers for petunias, acid-loving plants, houseplants, "bloom boosting," African violets and several different orchid formulas.

    Jack's Professional

    • These J.R. Peters fertilizers are designed primarily for greenhouse growers in the commercial horticulture and specialty agriculture markets. The Jack's Professional line includes more than 40 different formulations --- from chrysanthemum and fall and spring pansy fertilizers to poinsettia, tropical foliage and Easter lily products. The professional product line comes in 25-lb. bags that would take most of us a lifetime to use up.

    Other Peters Services

    • The J.R. Peters company also includes the J.R. Peters Laboratory, which chemically analyzes fertilizer solutions, water, plant tissue and growing media. The company also offers on-site quality control monitoring of fertilizer and soilless media production facilities. J.R. Peters provides toll manufacturing as well, or custom formulation, blending and packaging of private-label fertilizers.
