From an earlier post:
The book that I found extremely helpful and had suggested on an earlier post is Month-by-Month Gardening in Florida, Revised Edition (book) by Tom McCubbin. You can purchase it at Barnes & Noble right here in TV.
The other resource which is free to all of us is the Florida cooperative extension office, located right in the building on Morse and 466, where the sheriff's office is. You can arrange for a consultation with one of their representatives.
