We encounter countless questions about fertilizer at Pacific Northwest Garden Supply (PNW). Here’s one of the most common: what’s the best fertilizer to use? This, undoubtedly, is a challenging question to answer. It’s true – if you don’t know what you’re looking for, a wall-to-wall selection of plant food can be extremely overwhelming. But have no fear, the staff at PNW have narrowed down their top fertilizer picks for 2021. The following list is full of bestsellers that have been competing for decades to be the best in their field. However, before we unveil this list, it’s important to ask yourself a few questions: 

Important Questions to Consider 

Do you want to grow organic crops?  

If the answer is yes, consider selecting only organic fertilizers from the list below. High-quality fertilizers are typically divided into two categories: synthetic and organic. Synthetic, or mineral-based fertilizers are formulated from direct sources of bioavailable elements. Organic fertilizers, however, are formulated from naturally sourced compounds that become available to the plant once they are broken down in the root zone. In short, synthetic fertilizers feed the plant, while organic fertilizers feed the soil. 

Tip: Keep an eye out for the OMRI logo on organic fertilizers. The Organic Materials Review Institute (OMRI) reviews the manufacturing processes of all organic fertilizers against industry standards of production and ensures that all organic products meet necessary levels of quality. 

What system or medium are you using? 

This question refers to your method of growing. Some fertilizers aren’t suitable for use in specific systems. So, base your fertilizer of choice on your method of growing. Organic fertilizers, for example, can be made from extremely thick, viscous materials like fish hydrolysate. If used in a recirculating water garden, this compound would quickly become a bubbling mess of unimaginable chaos. If you’re unsure whether or not a specific fertilizer would be suitable for use in your garden, ask a PNW sales representative, or, refer to the “medium approved” icons available on fertilizer containers and feed charts. 

Base your fertilizer of choice on your method of growing.

How much experience do you have? 

There’s no shame in being a new grower. But if you’re new, it’s important to question your experience with plant food. Some fertilizers are more complicated than others. Complex fertilizers come in multiple “parts”, and need to be buffered, balanced, and measured in varying ratios over time. Even for the most talented growers, these complex feeding programs can be frustrating to manage. All of the parts of a base nutrient program are made up of similar elements, the only difference between them is the method of mixing and ratios during irrigation. So, it’s a good idea to question your capabilities as a gardener before selecting a fertilizer. In most cases, sometimes the easiest solution is the best choice. 

Some feed programs require a few bottles, and others require multiple bottles. Choose the program that fits your ability!
