When it comes to caring for your landscaping, the use of fertilizer can be critical for ensuring the success of your plants and grass. If you are caring for a lawn or garden for the first time, then you may have questions about fertilizers and which one is right for your needs. Before heading to your local garden center or hardware store in San Jose for fertilizer, it’s important to understand what an NPK ratio is.
N, P, and K, are the chemical symbols for nitrogen, phosphorus, and potassium. In terms of fertilizer, the NPK ratio describes the relative amounts of these 3 chemicals. No matter what type of fertilizer you buy, the label will include information about the nutrients that it contains. Also, every fertilizer will contain at least 1 of these 3 chemicals and will be marked with a “0” in the ratio for any that it does not contain.
