Marie, welcome to the sultry south. I'm sure you'll learn to love it.

I'd like to invite you to visit the Citrus Forum, which stays busy with people from all over. You'll find many answers to your questions just by reading old threads and many regulars who will jump in and help with specific questions.

As far as your lime (or other citrus) goes, no one can help you with the limited information given. When did you purchase the plants? Are they inside or outside? If the latter, what kind of light and/or lighting do they receive? An excellent potting medium is essential to successful citrus culture....what kind are you using? All citrus are pretty heavy 'feeders ' and will require fertilization.

Be sure to give information about your current USDA climate zone, too, when you post any questions in the forum.

I'll see you in the Citrus Forum!
