Understanding the Numbers on Bags of Fertilizer

2011 September 002.JPG

Bags or bottles of plant food always have three numbers

What do they stand for?

NITROGEN, PHOSPHOROUS AND POTASSIUM

What do they do for the plants?

UP, DOWN AND ALL AROUND

The numbers tell you what percentage of nitrogen, phosphorous and potassium it contains – in that order. In the bag shown in the picture above the numbers 8-4-5 tell you  the package contains 8 percent nitrogen, 4 percent phosphorous and 5 percent potassium.

An easy way to remember what each number represents is to think of them as “up, down and all around.”

The first number stands for Nitrogen which promotes upward growth of healthy green stems and leaves

 

The second number stands for Phosphorous and does two things…stimulates downward root development and lots of big beautiful blossoms (think huge flowers hanging down)

The third number, potassium, helps plants stay strong all around.
