There are volumes upon volumes written about fertilizer, so here are a few basics that can help you understand the importance fertilizer plays in the health of your yard and gardens. These tips should help you make the best choice for your next fertilizer purchase for successful Phoenix gardening.

How Fertilizers Help Your Arizona Garden

Some elements are necessary for plant growth. Essentially, there are 18 elements needed for healthy plant growth, including macronutrients such as nitrogen, potassium, and phosphorus. Any container of fertilizer will list three numbers, such as 10-30-20, 20-20-20, and so on. These numbers usually refer to the nitrogen, phosphorus, and potassium in percentage by weight. For example, a 100 lb. bag that is labeled 10-10-10 contains 10 pounds of phosphate, 10 pounds of nitrogen, and 10 pounds of potash. The remaining weight is filler that allows the fertilizer to be easily spread and to stop the possibility of damaging the plants with too much fertilizer.

Different Soils/Plants Need Different Formulas

Some fertilizers are packed for a specific plant type, such as roses, citrus, or azaleas. Some fertilizer products are made to acidify the soil. When gardening in Arizona, it should be kept in mind that our Arizona garden soil often contains calcium carbonate and is difficult to acidify. So if you want to plant acid-loving plants, you should use a container with potting soil mixture rather than our normal soil. You should try not to buy a fertilizer just because it says it’s for a specific plant without first checking the formula to ascertain that it is really what you need.

Applying Fertilizer to Your Arizona Garden

Different fertilizers are applied in different ways. For instance, a dry granular formula that can be evenly spread and watered is a good choice for lawns. Slow release fertilizers are best for container plants or as a top dressing. Water-soluble powders are a good choice for containers, as well as foliar sprays. You should always read the label and follow the instructions carefully, so as to provide the best fertilizer properties as possible.
