1. Complete Fertilizer

Three of the most important fertilizer elements are nitrogen, phosphorus, and potassium, and these are present in this type of fertilizer and other elements. A flower fertilizer contains a considerable amount of phosphorus compared to the other nutrients since this element is responsible for improving the root system of a flower. Phosphate also helps in enhancing the growth of your flower. Complete fertilizer constraints the three essential elements, also known as NPK.

2. Chemical Fertilizer

Chemical fertilizer contains artificial and inorganic chemical components like magnesium sulfate or ammonium nitrate. Chemical fertilizers are much cheaper compared to other types of fertilizers that you will find in the market. You will find different forms of chemical fertilizer, such as pellets, powders, and concentrated liquids.

These fertilizers can help speed up your plant’s growth process, for it quickly absorbs the nutrients that the fertilizer provides. However, if you overuse your chemical fertilizer application, this may lead to harming your plants, and the quality of its soil will no longer improve.

3. Organic Fertilizer

The advantage of using an organic fertilizer is that its components have limited formulation and these fertilizers are more expensive. Organic fertilizers can’t fix your plant’s problems, such as nutrient deficiencies in a fast period.

  • Slow-Release Fertilizer

All organic fertilizers are slow-release since it will take a period before it decomposes together with other soil microorganisms. This type of fertilizer has insoluble minerals and rock-like potash. If you only want to use your fertilizer once, you may opt for this type of fertilizer.

4. Foliar Fertilizer

Foliar fertilizers have a liquid form, and it is applied through the leaves of the plants and can easily absorb the nutrients it gives. Not all flower plants can absorb all the nutrients through its leaves; however, potassium is the nutrient that can mostly be absorbed when it was sprayed. If you notice that your plants’ leaves are turning yellow, there is a possibility that it is suffering from potassium or iron deficiency.

If this is the case of your plant, you can spray a foliar fertilizer to its leaves to improve its condition.

5. Simple Fertilizer

A simple fertilizer only contains the essential nutrients a plant needs: nitrogen, phosphorus, and potassium elements. This type of fertilizer is sold both in the form of organic or chemical.
