Is there a good article with pictures on how to properly plant the different species of plants in the substrate? I purchased two Amazon swords and some good substrate with tablets for them, but want to make sure I'm doing it right. A picture pointing out the various parts of it would be nice too, such as the rhizome and such. I believe I read the the rhizome needs to be above the substrate for rosetta type plants? What is the rhizome exactly? Sorry for my lack of knowledge, took physics instead of biology in school.
Also, what is the correct way to prune these when leaves go bad or any other situation?
