Characteristics of Mississippi’s Planting Region
Mississippi has a humid subtropical climate, defined by long, hot summers, mild winters, and abundant rainfall year-round. Its proximity to the Gulf of Mexico influences the state’s weather patterns, leading to a longer-than-average growing season and fewer temperature extremes than interior states.
What to expect as a Mississippi gardener:
- Summer highs range from 88°F to 92°F (31°C to 33°C)
- Winter lows typically stay above 30°F (-1°C) in the southern zones, and rarely drop below 20°F (-6°C) even in the northern areas
- Annual rainfall of 50–65 inches (127–165 cm), with most precipitation occurring in late winter and spring
- Growing season: typically 240 to 300 days, with the longest seasons along the Gulf Coast
- Soil types vary widely, from loamy Delta soils in the west to sandy coastal soils in the south and clay-rich soils in the northeast
With this long season and ample rain, Mississippi is one of the most versatile states for gardeners.
Challenges of Growing in Mississippi
High Humidity & Heat
Excessive moisture and high temperatures can promote fungal diseases such as powdery mildew, blight, and root rot. Many plants struggle without proper airflow or shade.
Heavy Rainfall & Poor Drainage
Some regions suffer from overly saturated soils, especially clay-heavy areas. Raised beds and proper drainage are important to prevent root diseases and waterlogged crops.
Pests
Mississippi’s warmth is great for plants—but also for insects. Common garden pests include: aphids, tomato hornworms, squash bugs, fire ants, and whiteflies. Organic pest control methods and crop rotation are essential here.
The Benefits of Using a Greenhouse in Mississippi
A greenhouse isn’t just for northern climates—it can be a game-changer in the Deep South, too.
1. Extend Your Growing Season
- Without a Greenhouse: Summer heat can overwhelm tender crops, and spring rains can rot early seedlings. Outdoor planting typically begins in early March and ends in late November in southern Mississippi.
- With a Greenhouse: You can ventilate, shade, and control watering to create the perfect environment, even in July. Start seedlings as early as January and grow cool-season crops well into December.
