Can I Make a Successful Liquid Fertilizer From Granular?

Posted on June 09 2023

There are various ways of converting granular into liquid fertilizer.

But what is liquid fertilizer?

Liquid fertilizer is a concentrated solution usually mixed with water and sprayed on the foliage and soil of your plants.

Liquid fertilizers are typically fast-acting, easy to apply, and effective - even in cold weather.

On the other hand, granular fertilizers can be more cost-efficient and easier to store.

Generally, these fertilizers feature a synthetic chemical mix of crucial plant nutrients, including nitrogen, phosphorus, and potassium.

This article will guide you through the question of whether you can make a liquid fertilizer from a granular one and how to use liquid fertilizer to enhance the growth and productivity of your plants.

What is a Granular Fertilizer?

Granular fertilizer is typically dry and available in the form of pellets or solid granules.

Most of them are slow-release fertilizers releasing nutrients to the plants over a long period.

However, you can also find quick-release granular products.

The Best Way to Make Liquid Fertilizer From Granular

Making liquid fertilizer from granular dry fertilizer is easy, and you can do it in your home.

You can make your liquid fertilizer using store-bought dry inorganic fertilizer or homemade organic manure, including compost, poultry, and cow manure or you can get the best of both worlds and purchase a water soluble fertilizer that comes in dry, powder form and dissolves instantly in water to become a liquid fertilizer. 

If you prefer the latter option, we have a large collection of water soluble fertilizers you can choose from in our shop.

However, if you prefer to make liquid fertilizer from a non-water soluble granular fertilizer, you can try the following:

  • Use one cup of fertilizer for every gallon of water (378l )

  • Dissolve your granular fertilizer in water and leave it for twenty-four hours. Remember to stir it regularly.

  • After 24 hours, sieve out the solids. You can then use your liquid manure at 1-2 cups for every perennial, 2-4 cups for every shrub, and 6-8 cups per tree.

  • The solids can be used as low-powered fertilizers and applied in established fields with plants requiring mild boosting.

If you want to make the best liquid fertilizer, you can use Greenway Biotech's top-quality, highly soluble organic fertilizers.

    Liquid fertilizer has been found to have numerous perks over granular fertilizer. These include:

    • Every drop of the fertilizer has the same ratio of nutrients creating an even availability and distribution of plant nutrients

    • They are easy to handle and apply than the granular fertilizers

    • Since they provide nutrients immediately, liquid fertilizers are the best choice for starting and dying lawns

      Yes, you can use both fertilizers at the same time.

      However, the two fertilizers should be compatible and applied in good measures.

      If not done carefully and correctly, it can damage your crops.

      When to Apply Granular Fertilizer and Liquid Fertilizer

      While granular fertilizers are slow acting, they tend to last longer than their liquid counterparts.

      This way, your soil stays fertilized for longer, and your crops will have sufficient nutrients throughout the season.

      Granular fertilizer is a perfect option for farmers or home gardeners searching for cost-effective, environmentally friendly, and longer-lasting solutions.

      On the other hand, liquid fertilizer is a great option if you are looking for a fast-releasing solution for a new or dying lawn or for vegetable plants that need an immediate pick me up so you don't lose your produce.
