Guide to 19-19-19 Fertilizer

A good fertilizer can make all the difference when it comes to plant growth. Therefore, it’s critical to know what kind of fertilizer you’ll use for your plants. So, let’s take a closer look at 19-19-19 fertilizers.

What Is 19-19-19 Fertilizer?

The 19-19-19 fertilizer, sometimes known as triple 19, is a fertilizer that you may use on any type of plant.

While the name may seem odd, the numerals refer to the NPK ratio. Nitrogen, phosphorus, and potassium are abbreviated as NPK.

The ratio indicates that the fertilizer consists of 19% nitrogen, 19% phosphorus, and 19% potassium. These ingredients are the essential nutrients that all plants need to be healthy and grow.

What Are the Ingredients in 19-19-19 Fertilizer?

Triple 19 fertilizer contains 19% nitrogen, 19% phosphorus, and 19% potassium. Each nutrient contributes to the plant’s well-being in some way.

Nitrogen encourages grass growth and gives plants a vibrant green hue. Phosphorus promotes the formation of roots in small growing grasses and encourages blooms.

Finally, potassium promotes the plant’s resistance to diseases, ensuring that it doesn’t become sick and die.

What Plants Benefit From 19-19-19 Fertilizer?

19-19-19 fertilizers can benefit almost any plant. Phosphorus promotes the blooming and fruiting of plants.

So, plants and trees that require extra phosphorus, such as orange trees, would benefit significantly from this fertilizer.

Triple 19 can also be applied to vegetable crops for better development and productivity and healthier growth.

19-19-19 Fertilizer Benefits

There are numerous advantages of using Triple 19 fertilizer. It aids in the overall growth of crops and boosts disease resistance due to its nutrients.

If your soil is particularly poor in quality, this type of fertilizer provides your plants with the nutrients they crave.

The triple 19 fertilizer can help avoid soil texture deterioration by replacing nutrients that are lost each growing season.

Because the majority of triple 19 fertilizers have low salt content, you won’t need to worry about excessive salt buildup, and your irrigation lines and nozzles shouldn’t clog either. 

When Is the Best Time To Apply 19-19-19 Fertilizer?

There is no set time as to when you should apply the fertilizer. It is, however, usually recommended to fertilize your plants in the spring or fall. You can even use it in both seasons if you like.

Because the weather is chilly in the spring and fall, you may use it about any time of day. If you opt to fertilize during the summer, do so in the early evening hours when the ground is dry.

19-19-19 Application Rates

When it comes to the rate at which NPK 19-19-19 is applied, it varies. The rate of application is determined by the brand as well as the size of the area you want to fertilize.

Foliar application is a method of fertilization in which fertilizer is applied directly to the leaves using a spray. Plants benefit from foliar spray because it helps them intake more water and nutrients. 

For foliar application (this triple 14 is designed exclusively for foliar use), dilute roughly 1 pound per gallon of water and apply 10 to 25 pounds per acre.

If you’re opting for soil application, it should be roughly 5 pounds for every 1,000 square feet, though rates will vary depending on the brand. 

On average, a 50-pound package of fertilizer will usually cover around 15,000 square feet.

Read the fertilizer’s directions beforehand to determine the exact application rate required.

How To Apply 19-19-19 Fertilizer

The process of applying 19-19-19 fertilizer is simple. The fertilizer can be applied in three different ways. The first choice is to rake, the second option is to use a spray, and the final option is to broadcast.


If you want to use the raking approach, the steps are easy.

First, place the required amount of fertilizer at the bottom of the plant near the roots. Then, massage the particles into the soil with a hand rake.


The spraying method is also very easy. All you need to do is combine water and fertilizer. The amounts necessary for the mix are usually specified on the fertilizer packages.

Spray the mixture straight on the plants with a sprayer until the foliage is soaked with water. If you’re going to spray a large area of plants, a backpack sprayer is a good option.

A backpack sprayer is essentially a tank that you wear as a backpack and spray the plants with the spray wand. It can cover a large area of plants.


With this method, you place the fertilizer into a handheld or push spreader, following the directions for application, and cover a large area relatively quickly.

Best 19-19-19 Fertilizer

There are many good 19-19-19 fertilizers that you can find on the market. However, you can never go wrong with the Grasshopper 19-19-19 Foliar Fertilizer.

This is a fertilizer that dissolves in water. Water-soluble fertilizers are excellent because their nutrients get absorbed immediately by the leaves and roots of the plants, so no unsightly granules are left behind.

The nutrients in the Grasshopper 19-19-19 Foliar Fertilizer ensure that your plants grow strong and stay healthy. The fertilizer is appropriate for a variety of plant environments.

Is Triple 19 Fertilizer Good for Your Lawn?

The 19-19-19 fertilizer can indeed be used on lawns, though it may not be the best option.

Most fertilizers made specifically for lawns have high nitrogen content and low phosphorous and potassium content.

This is intentional as established lawns simply do not need large amount of phosphorous or potassium. What the crave is nitrogen.

So, while triple 14 likely won’t hurt your lawn, using it is essentially wasting two of three nutrients. 

Is Triple 19 Good for Gardens?

19-19-19 fertilizer is great to use if you’re planting a vegetable garden. Your vegetables will grow healthy and strong since it includes the right levels of all the nutrients they require.

It’s best for cabbages, kale, lettuce, and spinach, among other leafy greens. However, it may be advisable to use vegetable-specific fertilizers for the greatest results.

Vegetable-specific fertilizers contain the exact amount of nutrients that the particular vegetable requires to thrive. Therefore, some vegetables will necessitate a different nutrient ratio than others. 

For example, if you’re growing tomatoes, you might require a fertilizer with a 1-4-4 ratio or choose to use a product such as Tomato-tone, specifically formulated for tomatoes.

On the other hand, if you’re growing lettuce, you’ll need a fertilizer with a lower concentration of phosphorous. 

In that situation, purchasing a vegetable-specific fertilizer may be the best option. It will ensure that all of your vegetables grow as healthy and strong as possible.

What’s the Difference Between NPK 19-19-19 and 20-20-20?

20-20-20 fertilizers are mainly used in gardens. The majority of those fertilizers may be used in the garden area at all phases of crop production. They contain equal amounts of 20% nitrogen, 20% phosphorus, and 20% potassium.

Some people, however, may find the fertilizer too powerful, so they opt to dilute it slightly before using it.

NPK 19-19-19 Fertilizer Price

The cost of 19-19-19 NPK fertilizers varies based on the brand and quantity. 19-19-19 fertilizers are available for as little as $25 and as much as $200.

Even though it seems that the fertilizer is expensive, it depends on the amount of the package. For example, if you purchase a 50lb bag, the price per pound will be lower than a 20lb bag.
