Citrus plants are so easy to grow. Yes...you can have fresh citrus fruits in the South. I had a Lime tree for 8 years in a big pot that produced tons of limes. All I did was bring the pot in the garage for the winter. They also make great house plants.
Citrus require minimum care. Just keep moist, fertilizer with a citrus fertilizer per directions, and spray with Triple Action Plus to control diseases and insects. Now you can make that perfect Key Lime pie...Yum
