About this item

  • OSMOCOTE QUALITY: Osmocote is the original slow-release plant food. Decades of rigorous field testing confirm product effectiveness with hundreds of plant species in a variety of climate and soil conditions.
  • OSMOCOTE’S BEST FORMULA: Each homogeneous granule contains 15-9-12 NPK plus micro and secondary nutrients and feeds up to 6 full months.
  • OSMOCOTE’S SECRET: Soil temperature controls how Osmocote releases its nutrients, and more importantly how nutrients are taken up by the plant. Replenishment and feeding are in natural harmony.
  • OSMOCOTE’S DIRECTIONS FOR USE: 1 pound of Osmocote covers 37.5 sq. ft. (approx. 6’ x 6’). Works best when mixed into 1 – 3 inches of soil. Package includes applicator. In containers, mix 1 pound with 19 gallons of potting soil.
  • OSMOCOTE IS MISTAKE-PROOF: Even if over-applied up to 3x the recommended rate, Osmocote does not ‘burn’ the plant.
  • OSMOCOTE CONFIDENCE: Performance is guaranteed. If unsatisfied, return the empty package to The Scotts Company for a full refund.

How It Works

Granule Coating

Osmocote Plant Food consists of a nutrient granule coated with semi-permeable resin.

Water Dissolves Nutrients

The coating permits water to penetrate the granule and dissolve the encapsulated nutrients.

Nutrients Released

These nutrients are released with changes in temperature. More nutrients are released during warmer active growing periods.

Empty Shell

The empty shell remains after nutrients are released.

I use this slow release plant food on my garden every two months, with regular fertilizer, Neptune Harvest, and also bone meal. I did notice that when I use this product my little hungry plants get stronger, and produce more fruits and veggies!We’ve been using this product for years in our garden, and it truly gives an extra boost to any plants. We get the large bags, then transfer them to a smaller shake container for easy distribution among our plants. Plus the small container helps my four-year-old daughter help sprinkle this product in our garden. Our garden truly thrives, and produces so many fruits and vegetables. We use it on almost everything: our flowers, strawberries, blueberries, melons, tomatoes, lettuce, garlic, cucumbers, onions, peppers, carrots, squash plants and more!We love the fact that Osmocote is not only slowly releases the nutrients into the soil, but also protects the nutrient core from being washed away or leached out. Never had an issue with the quality of this product. I truly believe this is a secret ingredient that all gardeners use to improve their garden! I highly recommend using for your plants, give it a try.

Reviewed in the United States on November 2, 2023
This stuff is amazing! Two years ago I bought a Hoya Kerrii and was told it would never grow and it never did. Until I ACCIDENTALLY put some of this stuff on it when I was putting it on my other houseplants (I don’t think you’re really supposed to use this on Hoyas).
Next thing I know, two new leafs emerged! Now look at it!!!! This stuff is crazy amazing!
