Yes, it was a good article to read. My poor little Meyer Lemon is nearly dead, there are a few signs of life at the bottom, but I'm not sure if they're the Meyer Lemon or the rootstock it was grafted onto.
I'm looking to order a new Meyer Lemon tree this spring, once warmer weather arrives so it can be shipped. It'll never rival Cindy's tree for production, but if I can get a couple dozen lemons from it, growing up on the 2nd floor in a south-facing window, I'll be happy.
