USDA Growing Zones Map for Missouri - Detailed Climate Classification for Agricultural Purposes in Missouri
In Missouri, the changing climate has led to some parts of the state experiencing an increase in growing zones due to warmer winter lows, a potential effect of global warming. This shift in weather patterns highlights the importance of understanding the local climate when it comes to gardening.
To help gardeners navigate this climate change, the USDA plant hardiness map of Missouri is an invaluable resource. This map, divided into planting zones based on average extreme winter low temperatures over the last 30 years, provides valuable information for both novice and experienced gardeners.
The map is divided into four planting zones: 5b in the north, 6a and 6b in the central regions, and 7a and 7b towards the south. A small area in the southeast corner of Missouri is in the warmer growing zone of 8a.
The map can be used as an excellent starting place for novice gardeners, offering a reliable reference to select suitable plants for their specific growing conditions. For experienced gardeners, the USDA plant hardiness map remains a reliable reference to ensure they are making informed decisions about their plant choices.
In addition to the USDA map, other factors influencing plant hardiness include humidity, winter sunshine, rainfall amounts, microclimates, and soil type. Microclimates, created by factors such as surrounding structures, hills, and valleys, can significantly affect the local climate, making it essential to consider these factors when choosing plants.
Soil type is another crucial element to consider. Different plants have varying soil preferences, so understanding the soil composition in your area can help you choose plants that will thrive.
To make the most of the USDA plant hardiness map, gardeners can use the provided map to find their location and determine their growing zone. The Missouri Botanical Garden, the organization that provides the Missouri Plant Atlas and issues a regular email newsletter including a free e-book titled "How to Grow Successful Tomatoes," is a useful resource for accessing this map and learning more about gardening in Missouri.
By consulting the USDA plant hardiness map before purchasing plants, gardeners can ensure they are making informed decisions about the plants they choose, leading to a more successful and enjoyable gardening experience.
