Garden FertilizersCommercial fertilizers are listed as 6-8-6 or 4-124 or some other series of figures. These rep resent percentages of nitrogen, phosphoric acid and potash, in the order named. The fist tends to stimulate vegetative growth, the second to strengthen the stems and the third to improve the fruit. Applications of three pounds to 100 square feet are liberal for the above formula; but for weaker mixtures such as 3-84 or 2-14 the doses should be four or five pounds.
These chemicals are clean and, especially in the first group, are concentrated, almost odorless, easily handled and cheaper in proportion to their content of plant food than are lower priced goods. They must not be allowed to lodge on foliage for fear of burning. Apply them either before or after digging or beside the plants as top dressings to be raked in the surface. Any surplus may be kept until the following year as they do not deteriorate.

SLOW-RELEASE FERTILIZERSSlow-release fertilizers usually are coated with sulfur or a polymer that breaks down based on temperature, moisture, time or a combination of any of the three.
Slow release fertilizers have a low burn potential, making them ideal for fertilizing plants and lawn during hot temperatures.
