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.
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:

Hi. Have a really small pond that I take all the water out before the cold winter hits in New Jersey. I have one marginal plant in it. It is in a pot. Can I over winter plant, pot and all in our vegetable garden ? Jim
If the plant is hardy to zone 6 you can plant the whole pot in your garden and dig it up next spring.
If the plant is not hardy, you can overwinter it indoors or in a garage where it does not freeze.

We don't recommend places to purchase, But I can offer an article on how to care for it. It will be treated like most aquatic plants:

Hi, Can I grow water/pond plants in water indoors? Thanks!
Yes, but change the water occasionally or it will get an odor. Circulating the water will help, too. And if the plant needs sun, be sure to site it near a window or in a sunroom. This publication has a lot of plant information.
Will yellow iris or water lilies tolerate 0.3% salinity?
No, both are freshwater species and will not tolerate that.
