The main differences between garden fertilizers are the N-P-K numbers on the label, the form the product comes in, and whether the maker describes it as organic. Matching those to what you grow usually matters more than choosing the largest bag.

Check how much area a bag covers and how often the maker says to reapply. Some listings give coverage in square feet and others leave it out. If your beds need work first, our guide on How to Amend Clay Garden Soil: A Step-by-Step Guide for Beginners covers the groundwork that fertilizer builds on.

Every specification on this page comes from each product’s Amazon listing, checked on 13 November 2026. We have not used these products ourselves, so the picks are based on published specifications only.

Quick picks

How we chose these

  • N-P-K analysis The three numbers show the nitrogen, phosphorus and potassium share the maker lists for each product.
  • Form and mixing Granules are spread on the soil, while water soluble and liquid feeds are mixed with water first.
  • Coverage and bag size Coverage figures help you match a bag to your bed size, but listings state them in different ways.
  • Organic status and listed extras Some makers call their product organic or OMRI listed, and some add microbes, mycorrhizae or calcium.

Only the maker’s own listing details are used here. Where a listing does not state a value, the table says Not stated.
