Aquatic Plants and Planted Aquariums 101

I admit it, plant friends; I was totally unaware of a total subsect of the plant community: the planted aquarium world. There is a whole corner of the plant world dedicated to elevating our common fishtanks to living, growing underwater worlds that look like art. Aquatic gardeners are using aquatic plants to aquascape insanely beautiful aquariums. It is biophilia in the highest sense because you have so many aspects of the natural world indoors, and you even get to keep cute fishies! I had many of you request this episode but, to be frank, I've only health with above-ground houseplants so I was totally out of my depths. I figured I’d turn to Karen, an avid aquatic gardener who has written a step-by-step tutorial on how to assemble planted aquariums for a chat about the basics of aquatic plants. Get ready to dive into the wild world of aquatic plants and gardening!
