First of all, any commercial box of fertilizer is going to have an NPK Ratio on the box. It is a series of three numbers: N is for Nitrogen, P is for Phosphorus and K is for Potassium. Each of the three macronutrients will play a significant role in plant development. The reason fertilizers have the NPK numbers on the box is because Nitrogen, Phosphorus, and Potassium are the three macronutrients that are usually not in the soil already. Nutrients like iron, boron, magnesium, and manganese are typically in the soil already. The way the ratio is written out is going to be important in plant development because plants utilize the nutrients in different ways. For example, nitrogen is good for lush green growth; phosphorus plays a key role in flower and bloom development; and potassium aides in root growth. It also works together with phosphorus to assist the plant in maturing the fruit or flowers.


If I were growing basil, for example, in which we really don't want the flower but want the green growth, I would feed it with a high-nitrogen fertilizer. Things that have high amounts of nitrogen are coffee grounds and cow manure. When you are picking out a fertilizer for flowers, you don't want anything that is high in nitrogen. Your focus should be something high in phosphorus and potassium. An example of that ratio would be a 155 fertilizer or a 455 fertilizer.




Something that a lot of organic gardeners use as a phosphorus fertilizer is bone meal. It has other nutrients but the main nutrient is phosphorus. For potassium, people might use things like green sand or kelp meal. If you are going to make your own fertilizer, make sure you know the average nutrient count of whatever you include.

The planning part of your garden is very important, especially if you have a new garden bed or if you have a new load of garden soil. Sometimes it pays to get your soil tested for macronutrients. Local agriculture extension services usually have a program where they'll test your soil. It is usually about $10 for the test, and you'll get your results back in about two weeks.
