An effective fertilization program is essential to promote a healthy soil and plant life. Here at the Grieder Garden & Design Center we understand that planning a fertilizer program can be difficult with so many choices available. We highly recommend that you call or stop by the Grieder Garden & Design Center with any questions about what, when, or how to start a fertilizer program.

How to read the numbers on fertilizer:
10 - 10 - 10
(N - P- K)

    • The first -10- stands for the percentage of Nitrogen (N), there is in the bag. If it were a 50lb bag there would be 5lbs of N. 
    • Nitrogen promotes color.
    • The second -10- stands for the percentage of Phosphorous (P), there is in  the bag. If the bag were 50 lbs there would be 5lbs of P. 
    • Phosphorous promotes root development.
    • The third -10- stands for the percentage of Potassium (K), there is in the bag. If the bag were 50lbs there would be 5 lbs of K. 
    • Potassium promotes vigor and fruiting.
    • Whenever applying fertilizer, always follow the label instructions. Too much or too little fertilizer can have a negative or little effect on the plant or soil. The label is the LAW, any misuse of the product may be hazardous. 


Tree and Shrub Fertilization Guidelines

    • Best time to fertilize for maximum uptake into the plant is early summer and early fall
    • 3 lbs. Nitrogen per 1000 sq. feet
    • Use fertilizer with a 3 - 1- 2 ratio, don't skimp
    • For mulched areas, add an additional 1 lb. Nitrogen to offset Nitrogen loss from decomposition
    • Newly transplanted or very mature plants are the least likely to respond
    • Do not fertilize plants under stress, they will spend energy growing not defending themselves from disease, insects, or environmental stress

Annual and Perennial Fertilization Guidelines

    • Fertilize full sun annuals at time of planting or when growth begins in Spring
    • 2.5 to 3 lbs. Nitrogen per 1000 sq. feet (shade plants at ½ the rate)
    • Always fertilize at time of planting, get off to a good start
    • Use a 1-1-1 ratio
    • Feed early and heavy, early Phosphorous deficiency is common
    • Follow up fertilization 1 to 1.5 lbs. Nitrogen per 1000 sq. feet
