My Daughter and Son-in-Law came up from Florida for Christmas amd they brought something different with them for me to try my hand at...
A Persian Lime Tree.
After reading about it for a short time, I can grow citrus trees here in Pennsylvania, if I do it in a pot and put it in a southern exposure window.
The challenge begins with finding a 30 or 36" pot, the right soil and fertilizer, and honing my pruning skills.
I think I can do it. We shall see.
The tree is about 2 feet tall and is loaded with blooms and tiny Limes already.
If things don't work out, I will take to Florida with me next time and plant it in their yard.
