What to plant each month in Port St. Lucie

The vegetable season is reversed from most of the U.S.: the main planting window is September through February, with tomatoes, peppers and squash growing through the mild, dry winter. By March the season winds down. Summer brings heat, heavy rain and pests, so summer planting is limited to tropical crops such as sweet potatoes, pineapple, ginger and heat-tolerant herbs.
