When to Use Water Soluble Fertilizer

DIY Lawn Care with these organic fertilizersA water soluble fertilizer is one that may be dissolved in water and then added to the soil in a liquid form. These fertilizers are very convenient because it can be much easier to control the amount of nutrients that each plant needs due to the fact that they are in a measureable liquid form.


Most water soluble fertilizer solutions that are available on the market today will have a particular set of numbers listed on their label. These are known as the N-P-K numbers. N-P-K numbers are an indication of the smallest percentage the water soluble fertilizer has of each element listed. The reason why these numbers appear on many fertilizer labels in this fashion is so that the company’s competitors will not know the exact amount of each element that is in the fertilizer. This prevents fertilizer companies from copying an exact formula from one another.

When to Fertilize?

The very best time to use a water soluble fertilizer is when you first place your plant into the ground. The top three elements that are inside of most water soluble fertilizer products are Nitrogen, Phosphorus, Potassium or Potash. These are the three most important elements when it comes to healthy plant growth. Other elements that can be found in various fertilizers include Calcium, Magnesium, Iron, Sulfur, Manganese, Boron, Molybdenum, Zinc and Copper.

The reason why you should use fertilizer during the earliest stages of your plant’s life is because it is in need of the elements that fertilizer contains at this crucial time of growth.

What Nutrients Are in Fertilizer?

Nitrogen is the most important nutrient that a plant can receive. It helps to control the production and the amount of protein that is made available to the protoplasm inside the plant; this allows new cells to be made. Nitrogen also helps to produce chlorophyll which will make your plants look greener and healthier. It is also an element that aides in overall growth and strength.

Phosphorus is vital at the beginning of a plant’s life because it is necessary for photosynthesis to begin. It also allows energy to transfer freely within the plant to provide more strength and promote healthy germination. The flowering stages of the plant’s growth and seeding abilities also greatly benefit by the amount of Phosphorus that it receives.

Potassium, which may also be listed as Potash, can provide your plants with the healthy distribution of sugars and starches along with promoting growth by enhancing cell division. Potassium can also help to add to your plant’s chlorophyll levels and improve a plant’s stomata, which is responsible for helping your plants make more use of the light and air that is around them. While Potassium is important during the early stages of a plant’s life, it is also equally important all throughout the life of a plant in order to help increase plant growth.

Obviously the best time to use a water soluble fertilizer that has a high N-P-K percentage would be at the earliest stages of your plant’s life. By applying the fertilizer then, you will help to ensure that it reaches its optimal growth, stays green and healthy-looking much longer with boosted photosynthesis. Be sure to add fertilizer throughout the plant’s life so that its Potassium levels can stay high and continue to improve the plant’s growth.
