The best way to prepare homemade fertilizers is by creating your own concoction out of simple kitchen items. For example, you can use banana peels, coffee grounds, Epsom salt, etc. These are the most basic ingredients that are easy to obtain from any nearby store.

In this article, we will be going over the details of why homemade fertilizers are effective, what fundamentals you need to consider, and how you can make these on your own despite being a first-timer to the task.

So, without any further ado, let’s get started.

Natural Fertilizer Versus Synthetic Fertilizer

Natural fertilizer or Synthetic fertilizer, which one should you opt for? This debate has been there for ages.

Essentially, organic or natural fertilizers are produced from earthly substances such as mushroom manure, cow manure, bone meal, kelp meal, etc. On the other hand, Synthetic fertilizers are artificial fertilizers that contain manufactured materials, such as Ammonium Phosphate, Superphosphate, Potassium Sulfate, etc.

Here are some pros and cons of these two fertilizers:

Organic Fertilizers


  • Better infiltration and water holding capacity
  • No toxin buildup
  • It breaks contaminants down.
  • Improves soil fertilization
  • Fosters a sustainable ecosystem


  • Difficult application process
  • Slower results
  • Nutrients and microorganisms in the soil may vary

Synthetic Fertilizers


  • Affordable
  • Easy application process
  • Ensures rapid results


  • It doesn’t contain organic micronutrients
  • May add toxic elements in your plant food due to heavy use of the product
  • This may release the nutrients slowly or too quickly

Benefits of Using an Organic Fertilizer

Whether it is synthetic or organic fertilizers, both have their own benefits for the plants. Although organic fertilizer appears to be more useful in terms of providing the secondary and micronutrients plants need.

One may use natural substances like fresh grass clippings, coffee grounds, egg shells, etc., to make his own organic fertilizer for garden plants.

Organic fertilizers are one of the healthiest ways for plants to be fed. They are also considered safer for the environment, as synthetic fertilizers can potentially contaminate nearby water.

Why Composting Will Help

Composting is generally the process of decomposing organic materials such as grass clippings, organic waste, leaves, etc. You may even compost tea bags as they contain essential nutrients to feed the soils.

If you wonder how your own compost can help make fertilizers, it adds some crucial organic substances that help rapid plant growth. Also, this has a significant contribution to the soil structure as it keeps the soil healthy with proper moisture, nutrients, and air.

There are several types of homemade compost ideas available that you may try out. However, we suggest using the bokashi composting method as this helps upkeep a faster soil fermentation.

Healthy Soil in the Garden and Around the Farm is Key

Soil is an essential part of growing plants. Not only does the soil provides plants with the proper nutrients to grow, but it also gives them the foothold they need. Therefore, soil quality is vital to organic gardening and even farming.

Soil structure, along with soil nutrient density, is the foundation of a thriving organic garden. Healthy soil produces a bountiful harvest of healthy crops, as well as healthy plants like some acid-loving plants, with every growing season.

Understanding the Basics of N-P-K

Nitrogen, phosphorus, and potassium are three of the most important nutrients found in most fertilizers, and these are usually known as the “Big 3” or, in other words, N-P-K.

However, understanding the benefits of these nutrients – and how they work – is crucial to growing healthy plants. Here’s everything you need to know,

The Big 3, a.k.a N-P-K, significantly contributes to the plants’ growth. As plant roots reach down into the soil, they find these nutrients and absorb them to enrich their overall health.

For instance, Nitrogen in fertilizer is a slow-release product that is beneficial to the leaves. Phosphorus is known to help the roots grow and rapid fruit production in the plant. In contrast, Potassium is mainly used to support the plant, absorb moisture and grow better.
