How to Read a Label

A Guaranteed Analysis statement must appear on all mixed fertilizer labels. The label must indicate the proportion of each element present, as well as its sources (in this example, ammonium phosphate, potassium nitrate, etc.). The numbers 8-10-8 denote the percentages of nitrogen, phosphorus, and potassium present in this mix. This example contains 8 percent nitrogen, 10 percent phosphorus, and 8 percent potassium. Some fertilizers also contain secondary and micronutrients. Look for fertilizers with micronutrients derived from EDTA complexes as they are water soluble and hence immediately available to the root system. Rose foods containing all three levels of nutrients (primary, secondary, and micro-) are the best choice. In some cases, a soil penetrant will be added to the fertilizer to assist in delivery of the nutrients in clay soils.

Roses are heavy feeders. They require a constant supply of nutrients to sustain growth and bloom production. Here are two methods that will meet their demand for food:

1. The Organic Method: For a continuing cycle of decomposition, regularly space applications of fertilizers on the rose beds about every four weeks. It is best to work the fertilizer into the upper soil levels. This program can be supplemented with biweekly applications of fish emulsion.

2. The Chemical-Fertilizer Method: Start with a time-release synthetic in the spring and reapply midsummer, with monthly applications of a complete rose food (with all primary, secondary, and micro-nutrients) in between major feedings. Always follow label application and safety instructions when using a chemical rose food.
