Who Is This Plant Food Meant For?

If you’re searching for slow-release plant food, this is one of the top-tier products to consider.

Osmocote is owned by Scotts, one of the most prestigious gardens and lawn care companies worldwide.

With each scoop, you can offer up to four months of nutrition, so your plants don’t have to be fed as often.

Plant owners with both indoor and outdoor gardens will especially love this formula.

Instead of investing in several different products for all of your plants, this option is very versatile.

It will feed your plants through their active growing season and while they’re dormant to prepare them for warmer weather.

The all-in-one granules contain all of the necessary amounts of nitrogen, phosphorus, and potassium to ensure plant health.

What’s Included?

With your order, you’ll receive a bag of plant food that can easily be distributed in your gardens.

It can be beneficial to opt for an alternate storage container to keep the nutrients fresh.

Also, we recommend getting a scoop or measuring cup to measure the required amount of food accurately.

Depending on your gardens and plant pots’ sizes, you will likely have to mix different ratios.


Overview of the Features

Feeding your plants is essential to their overall health and vitality.

With products like this, you are given the ability to provide essential vitamins and nutrients to your plants.

  • NPK Ratio

The NPK ratio/fertilizer analysis of this plant food is 19-6-12.

For beginners, these figures mean you’ll have 19 nitrogen, six phosphorus, and 12 potassium.

It’s a rather versatile blend of nutrients that can accommodate most plants with a generic diet.

By keeping the granules dry, you can get up to eight years’ worth of use before spoilage.

  • Slow-Release Formula

Instead of immediately feeding plants and shocking their systems, this plant food releases slowly.

As it immerses itself into the soil, the nutrients will be distributed with every watering.

This process allows the root systems to soak up all of the nutrition they need over an extended period.

Slow-release formulas are also ideal for helping lessen the time it takes to maintain your gardens.

You’ll only have to worry about feeding your plants every three to four months instead of weekly.

  • Indoor/Outdoor Formula

This feature is particularly beneficial for apartment gardeners, as it can be used with indoor and outdoor plants.

Some types of plant food are only recommended for in-ground garden beds.

Fortunately, there’s the perfect number of nutrients for all of the plants in your home with this product.

After finding the accurate dosage for your plants, you’ll want to spread the plant food throughout the soil.

Ensure that you thoroughly water the soil so that the granules can begin to release the nutrients to your plants.
