How to Fertilize Plants Grown in Water

Plants grown in water are a popular form of indoor gardening since they require less maintenance than soil-grown plants. However, as plants are not receiving nutrients from soil, proper fertilization in water-grown plants is essential for their growth and health. In this article, we will cover the basics of fertilizing plants grown in water.

Preferred Fertilizers for Water-Grown Plants

Most liquid fertilizers can be used for water-grown plants, but it is important to select a type that is suitable for hydroponic or aquatic plants. These fertilizers are formulated to be water-soluble and have the necessary nutrients to ensure the plants grow healthy and strong. Some types of fertilizers that are commonly used for water-grown plants are:

Hydroponic nutrients

Aquatic plant fertilizers

Liquid seaweed

Fertilizing Water-Grown Plants

Before fertilizing water-grown plants, it is important to check if the water that is being used contains any nutrients. If the water is already rich in nutrients, then fertilizer may not be necessary. However, if the water is nutrient-deficient, then it is important to add fertilizer to help the plant grow.

The amount of fertilizer that should be used depends on the size of the container and the type of plant being grown. It is generally recommended to follow the instructions on the fertilizer packaging and use it as per the prescribed dosage. Over-fertilizing can cause more harm than under-fertilizing, resulting in stunted growth or even death to the plant.

Timing of Fertilization

The timing of fertilization is crucial for the growth of water-grown plants. It is recommended to fertilize the plant once a week or at least once every two weeks during the growing season. However, it is important to note that fertilizing during the dormant season is not necessary as the plant will not be growing actively.

It is important to check the pH level of the water regularly and make sure that it is within the preferred range for the plant being grown. If the pH level is too high or too low, the plant will not be able to absorb the nutrients from the fertilizer, resulting in stunted growth.

Final Thoughts

To summarize, fertilizing water-grown plants is crucial for their growth and health. It is important to use the preferred type of fertilizer and follow its instructions carefully. The timing of fertilization and checking the pH level of the water should also be taken into consideration to ensure the best results for water-grown plants.
