Aquatic Plant Fertilizing

Question

Hello, I am growing the plant “Egeria densa” and I am confused on how to fertilize this plant. I am doing an experimentation utilizing liquid fertilizers and would like some advice on how to fertilize submerged aquatic plants like this one.

Answer 1

Aquatic plants get their nutrition through the leaves from the water, instead of their roots like above-ground plants. Depending on the plant there are three types: liquid, tablet and granular. A slow release form is generally recommended. Here is more info:
