Missouri Climate Overview
Missouri’s weather requires growers to adapt to fluctuating temperatures and precipitation patterns. Understanding the climate’s impact on agriculture helps gardeners and farmers make the most of their growing efforts.
Winters
Missouri’s winters can be cold, with average lows in January around 20°F. Snowfall varies, averaging 13 inches annually, and ice storms occasionally cause significant damage.
Summers
Summers in Missouri are hot and humid, with highs averaging 88°F in July. Heatwaves and sudden storms often impact outdoor growing conditions.
Precipitation
The state receives an average of 43 inches of rainfall annually, ranging from 35 inches in the northwest to 55 inches in the southeast. Heavy rains can lead to flooding in low-lying areas.
Growing Season
The frost-free growing season lasts about 170 to 200 days, depending on location. Late spring frosts and early fall frosts shorten the effective growing window for many crops.
Challenges of Growing in Missouri
Missouri’s diverse weather patterns can complicate outdoor gardening. Each season presents unique hurdles that require strategic planning and adaptability.
1
Short Growing Seasons
Frosts in spring and fall limit the planting and harvesting periods, especially in northern regions.
2
Heavy Rain and Drought
Intense rain events can cause soil erosion, while summer droughts often stress plants and reduce yields.
3
Pest and Disease Pressure
Warm, humid conditions foster pests like aphids and diseases such as powdery mildew, increasing the need for protective measures.
Benefits of Greenhouses in Missouri
Greenhouses offer a reliable way to navigate Missouri’s challenging climate. These structures empower growers to overcome seasonal limitations and optimize crop production:
- Extending the growing season from early spring through late fall or year-round with proper heating.
- Protecting crops from frost, hail, heavy rains, and high winds.
- Providing controlled irrigation to conserve water and manage drought conditions.
- Shielding plants from pests and wildlife.
Key features for Missouri greenhouses include durable, snow-resistant greenhouse frames, UV-protected panels, and efficient ventilation systems to combat summer humidity.
Best Greenhouse Designs for Missouri
Selecting the right greenhouse design is essential for success in Missouri’s unpredictable climate. The structure must withstand temperature fluctuations and seasonal extremes.
Structural Features
Missouri greenhouses must withstand variable weather. Steel or aluminum frames offer durability against snow and storms, while UV-resistant polycarbonate panels provide insulation as well as light deprivation and light diffusion according to your crop and harvesting needs.
Roof Designs
Using a Gothic Arch greenhouse can be smart in places with cold, wet winters and lots of snow. They prevent snow buildup. Semi-gable roofs can also work well in regions of the state where they experience less snow compared to higher rainfall.
Temperature Controls
Passive solar heating designs combined with supplemental options like propane or geothermal systems ensure year-round use. Wet wall cooling systems and shade cloths help regulate summer temperatures.
