I am growing the plant shown below. The plant is dying, and I do not know how to reverse it. Does anyone know what kind of plant I am growing here? It looks like a cactus, but I am stuck with that.
That looks like an aloe (or something along those lines). I have one out on my porch here in Vegas and never water it. It loves the dry desert-like atmosphere. I suggest not to over-water it. Put it outside when it starts warming up. Try a new pot and new soil.
The plant is an Aloe Vera. Here are a few links on how to take care of it. My mom has had one for years and any time I have a skin irritation or anything We cut a small branch off and then splice it in half and use the pure aloe to sooth it. It's the best. Here are a few links on how to care for it and what it needs. Putting it outside is a first step. http://www.ehow.com/how_2086446_keep-aloe-alive.html http://www.recipegoldmine.com/gardengary/aloe-vera.html
I used to grow those in our backyard, awesome for skin. Don't over water them, they love HOT and dry atmospheres. I grew mine in Saudi Arabia, where they thrived in the summer. Try re potting it to make sure the soil isn't too damp.
