It’s springtime and after a long winter of brown grass (or maybe you could not see the grass because of snow), you are ready to drop some fertilizer and kick-start your lawn. Outdoor barbeques and touch football are just around the corner!

But…what is the best fertilizer to use on your lawn? Here we will list our top picks for good, all-around fertilizers for spring application.

About fertilizers: Always apply at the rates recommended and use the volumes of water required after application. More is not better. Too much fertilizer in soil can alter the osmotic conditions around grass roots and prevent water uptake.

4. Miloganite 0636 Organic Nitrogen Fertilizer

Product Highlights

Milorganite Organic Nitrogen Fertilizer comes in a 32 lb. bag and covers 2,500 square feet of lawn.

It retails for $33. The NPK ratio is 6-4-0. It is a slow-release material, necessitating reapplication every 10 weeks.

Milorganite is heat-dried bacteria (biosolids) produced following organic digestion of material in wastewater treatment plants in Milwaukee, Wisconsin. Its production represents the first government-registered recycling project, starting in 1926.

Milorganite works by adding organic matter and nitrogen to the soil, thus feeding indigenous microbes which produce byproducts that feed plants. Approximately 80% of the nitrogen in Milorganite is not water-soluble and must be released through microbial action.

It therefore acts in a slow-but-steady manner as a fertilizer and will never burn turf grasses. For this reason, it is highly favored for large turf grass areas such as golf courses. It is applied by spreader.

Features

  • Organic
  • Proven performance (90 years)
  • Bacterially-controlled release (will never burn grass)
  • Kid and pet friendly

The Good

This tried and true organic fertilizer will not burn your turf grass and is very kid and pet friendly since most of the chemical components are rather inert. Soil bacteria must access nutrients in the Milorganite and release it, so release is at the rate of the natural soil ecosystem.

This also means that leaching to waterways is of low concern as well.

The Bad

It acts slowly and is dependent on several existing conditions for proper action, which include healthy soil chemistry and microbial ecosystem. Some users have reported no positive results, likely because their soil conditions were poor.

Pros
  • Kid and pet friendly
  • Non-polluting
  • Organic
  • Will never burn your lawn
Cons
  • Slow acting
  • May not help restore lawns in bad or abused soils

5. Espoma ELF20 Organic All-Season Lawn Food

Product Highlights

Espoma Organic All-Season Lawn Food comes in a 28 lb. bag and covers 5,000 square feet of lawn. It retails for $50.

The NPK ratio is 9-0-0, meaning is straight nitrogen, but also includes three species of Bacillus bacteria due to its organic origin (feather meal and poultry manure). It can be applied by spreader.

Features

  • Kid and pet friendly
  • Covers 5,000 square feet
  • NPK ratio 9-0-0
  • Includes helpful bacteria (BioTone)

The Good

Users like that fact that the fertilizer only needs to be applied 3-4 times per year. It is also non-toxic, so it is safe around kids and pets.

The Bad

Some reported quality issues with damp fertilizer, resulting in clumps that cannot be spread. There are also reports of nitrate burn, however, rates used cannot be verified.

Pros
  • Organic
  • Non-toxic
  • Contains helpful microbes
Cons
  • Some users report nitrate burn
