You’ve tried to place it in a sunny or shade area but things don’t get any better? You’ve tried watering it properly too? Well, check it out you may forget to put your organic garden fertilizer in it!

According to Oxford dictionaries, fertilizer is a chemical or natural substance added to soil or land to increase its fertility. So, putting fertilizer on your garden is important since you want the best place for your plants to grow. Your garden’s soil could be in an unbalanced environment, especially when you’ve been growing the same plant over and over. You need to restock your plant’s food with fertilizer. For starters, you can test the soil pH levels and the soil acidity. Remember to balance, not putting too much element in your soil.

When you put too much element from the fertilizer, for example, phosphorus, you could end up killing your plants. And even damaged your environment. When your soil was washed away in rains it could also pollute waterways nearby!

As mentioned earlier, your plants need nourishment. The food they should get from the soil is nitrogen (N), phosphorus (P), and potassium (K). This element is also commonly found in fertilizers. If your soil is deficient in these materials, using fertilizers, your plants will still get their food portions.

Synthetic Fertilizers

Your plants cannot recognize the type of fertilizer you are applying, whether synthetic or organic. Synthetic fertilizers usually offer faster results and you may be tempted by them. But remember, synthetic fertilizers are made for plants only. This can make the quality of your soil degrade and you must continue to apply the fertilizer in more intensity. Also, synthetic fertilizers are made from unsustainable materials so that organisms and earthworms die.

Organic Fertilizers

Meanwhile, the function of organic fertilizers is to improve the soil where your plants grow. Using organic fertilizers for your garden can make the soil lighter. This will help the plant breathe because there is air in the soil. Unlike inorganic fertilizers, organic fertilizers do not use excessive nutrients that are wasted when used all at once. Organic fertilizers also do not contain a lot of salt so that earthworms can live and help plant growth in your garden.

If you are a professional gardener, you must realize that the ingredients in organic fertilizers are the active ingredients. This means that the material can change over time because it meets other materials and its components can change in each batch.

On buying organic fertilizer, you must also pay attention to the use of the word organic in the fertilizer you want to buy. Some sellers keep putting the word ‘organic’ on their fertilizers when in fact they don’t. To see its accuracy you have to look at the ingredients it uses and check it out from the Organic Materials Review Institute.

Types of Organic Fertilizers


This type of dry fertilizer is probably the most common fertilizer you will encounter on the market. This fertilizer is usually then mixed in the planting medium or soil where your plants grow. This fertilizer can be used in anything, whether you plant it directly, plants in the yard, even crops in the fields.


Liquid fertilizers are generally used so that the composition they contain is absorbed more quickly. This liquid fertilizer can be applied to the roots by sprinkling it on the ground or spraying on the leaves. A liquid fertilizer sprayed on the leaves is generally used during the growing period, especially for plants with the most prominent leaves. For plants that require liquid fertilizer for their leaves, at least regular watering is required every two weeks.

Growth Enhancers

Growth enhancers, just like the name, are fertilizers that collect all the good substances that are there for your plants. This good substance, for example, is seaweed, which can increase the flow of air into the soil and smooth the passage of minerals and substances that plants need. However, this substance is also too much because the soil should already contain all the substances your plants need, namely microbes, enzymes, and humic acid. So spending your money on growth enhancers is a money-consuming decision.

How to Use Organic Fertilizer

Use the organic fertilizer that you bought according to the instructions. Some fertilizers take a long time before they show results. If you didn’t follow the instructions, you could end up burning or healing sensitive plants. For indoor plants or areas that you frequently visit, you should avoid fertilizers with strong aromas such as fish emulsion fertilizers.
