Meyer Lemon Tree

So, I'm venturing waaaaaay out of my comfort zone.  I have planted a Meyer Lemon Twig (soon to be tree, I hope). I cooked with Meyer Lemons once only because I haven't been able to find any since the Spring time when I made Martha Stewarts, Meyer Lemon Pound Cake.  Meyer Lemons are gourmet lemons that look almost like small oranges, their aroma is ten times stronger than the normal lemon.  I found them at, of all places, Walmart but I haven't been able to find them since, nowhere!  I was so frustrated so I did some research online and come to find out they are harvested in the Spring.  That's the bad news, the good news is that in my research I found out that I can grow a lemon tree . . . . . , in my house!!  As long as it's in a sunny spot and kept warm, I can have Meyer Lemons year round?!!!  WOW!!  I just hope I don't kill it because I do tend to have a "brown" thumb.  The window ledge above my kitchen sink is called, "Death Row" by my daughter.  That's how bad I am with plants so, I'm hoping and praying and hoping and praying that I don't botch this one.  Hubby planted it in a giant pot and placed it in our "sunroom".  If you have any tips for me, please feel free leave me some, I need all the help I can get with my new baby.  Thanks!
