Growing in Lakeland's Climate
Lakeland's subtropical climate offers a long growing season, but it also brings challenges such as intense summer heat, heavy rainfall, humidity, and pest pressure. Commercial growers around Polk County produce tomatoes, peppers, cucumbers, melons, and sweet corn, while home gardeners grow everything from herbs and greens to tropical fruits.
Choosing seed varieties bred for heat tolerance and disease resistance is essential. Many Florida gardeners plant cool-season crops in fall and winter and switch to heat-loving varieties in spring and summer.

Tips for Choosing Seeds in Lakeland
Check planting calendars from University of Florida IFAS Extension resources to time your plantings correctly. Look for heat and humidity tolerance, disease resistance codes, and days to maturity. Start small with new varieties, keep records of performance, and consider succession planting to extend harvests.
Storing and Saving Seeds
Proper storage keeps seeds viable for future seasons. In Lakeland's humid climate, moisture is the biggest enemy, so store seed packets in airtight containers with silica gel packets and keep them in a cool, dark location such as a refrigerator. Label containers with the variety and date. Gardeners who save seeds from open-pollinated and heirloom plants should allow fruits to fully mature, clean and dry seeds thoroughly, and keep records of which plants performed best. Over time, saved seeds can become better adapted to local growing conditions.
Gardening Calendar Highlights for Lakeland
Central Florida gardeners often follow a calendar that differs from much of the country. Fall and winter are ideal for lettuce, broccoli, carrots, kale, and herbs like cilantro and parsley. Spring is a prime time for tomatoes, peppers, beans, and squash before the intense summer heat arrives. During the hottest months, many gardeners switch to heat-tolerant crops such as okra, southern peas, sweet potatoes, and tropical greens, or use the season to improve soil with cover crops.
