Fertilizers come in a variety of types and applications, but one of the most important aspects is to know what type you need and how much of it you should use. A common fertilizer used by many gardeners is 21-0-0 Fertilizer. This blog post will discuss what this fertilizer does and how to apply it for the best results!
What Does 21-0-0 Fertilizer Mean?
21-0-0 fertilizer is made up of three numbers that represent the percentage by weight of nitrogen, phosphorus, and potassium. In this case, it’s 21% nitrogen, 0% phosphorous and 0% potassium.
In other words: it’s a complete fertilizing product with a high concentration of Nitrogen (N) so be careful to use only as directed!
Nitrogen is a critical nutrient that plants need to grow. It makes up for over half of the dry weight of plants and it’s found in chlorophyll which gives leaves their green color. Plants also require nitrogen as fuel for cellular respiration, so this fertilizer will help plants grow and stay healthy.
However, you should be careful with nitrogen fertilizers because too much of it can actually inhibit plant growth! Some plants like tomatoes and peppers need less than a full percentage or there is a risk that they won’t bear fruit. So don’t go overboard when applying your 21-0-0 fertilizer to these plants!

How to Use 21-0-0 Fertilizer
Applying a nitrogen fertilizer is pretty simple and can be done in many different ways depending on what you’re working with!
For smaller plants, like vegetables in planters or pots, just sprinkle the granules around them until they are lightly covered if it’s already been mixed into your soil when planting. For bigger plants that have been planted outside in beds or containers, add some fertilizer around their roots after watering so it absorbs easily through its leaves. If using liquid fertilizers for larger gardens of flowers and grasses in open spaces, measure out how much you need depending on how big your area is. Add these amounts to a bucket of water before pouring over the plants, then repeat once a month for the best results.
