What do the numbers on the fertilizer package mean?
Rate This FAQ
N-P-K. The first number (N) is nitrogen is an important element for leaf growth, color and development. Phosphorus (P) is used by the plant for root development and seed production. Potassium (K) is used by the plant for disease resistance, hardiness and sugars. Sometimes a fourth number may follow the third, indicating presence of another element like sulphur, iron or zinc. Federal and State laws require all fertilizer labels to represent the actual percentage of nitrogen, phosphorous, and potassium by weight. Thus, ammonium sulfate (21-0-0) contains 21% nitrogen by weight and provides neither P nor K.

- I am in West Valley city, and for the past 3 years my grass has looked really good, and last year, the entire front park lane died, and I now have large areas in the front yard that are dead as well. I have heard of grubs, however I have no idea how to identify what is going on with the grass or how to treat it. You can pull up larges patches of grass easily, there don't appear to be any roots in some areas and I would like my grass to be pretty again. What can you recommend?

- I have a scarlett red maple. It's about 8 years old and last year the leaves didn't get very big. This year, it hasn't even began to bloom yet although, It has tiny buds. I noticed that the bark in some places peels off very easily. Under the bark, it looks like there may be some black flecks (maybe bug feces). I only noticed one little red colored bug under where I peeled the bark. I don't see any other bugs anywhere, even at the base. Do you think it could have a disease or bugs? I am going to put some fertilizer steaks around it and pour some Bayer Advanced tree and shrub insect control around the base of the tree. Is it too late to spary it?
