USDA's Plant Hardiness Zone Map Updated for the First Time in Over a Decade: The updated USDA plant hardiness zone map reflects climate changes, bringing new gardening possibilities for some regions
The USDA's plant hardiness zone map, a widely used tool for gardeners, has been updated for the first time in over a decade. This update is significant as it indicates which plants will survive in specific locations based on climate conditions. Daniel Wood, a graphics reporter at NPR and an avid gardener, explores the changes in this episode of Life Kit. The map's update is essential due to climate change causing shifts in temperature patterns. These changes may bring new gardening possibilities for some regions, making it an exciting time for gardeners. Support for this NPR podcast comes from various sponsors, including Whole Foods Market, Amgen, Bluehost, Atlassian, and BritBox. These sponsors offer products and services that cater to various needs, from hosting plans to collaboration software and biotechnology solutions.
Determining Survivability of Plants with USDA's Plant Hardiness Zone Map: The USDA's Plant Hardiness Zone Map helps gardeners choose plants likely to survive their winter based on historical average low temperatures. Gardeners should use it as a guide to inform decisions about potential plant success in their garden, particularly for perennials.
The USDA's Plant Hardiness Zone Map, produced by the United States Department of Agriculture, is a useful tool for home gardeners to determine which plants are likely to survive the winter in their specific location based on historical average low temperatures. The map is divided into 13 zones, with 1 being the coldest and 13 being the warmest. Recently, about a quarter of the country has moved into a new zone due to climate change and an increase in weather stations, making it essential for gardeners to consult the updated map for accurate plant selection. The map is not a definitive guide, but rather a risk assessment tool to help gardeners make informed decisions about the potential success of various plants in their garden, particularly perennials, which are plants that survive for multiple years. Gardeners should consider the cold tolerance of their perennials in relation to their zone to increase the chances of a successful garden.
USDA Hardiness Zones: A Useful but Limited Tool: While the USDA Hardiness Zone map helps gardeners choose plants that can survive winter temperatures, it has limitations. It's based on historical data, can't predict future climate conditions, and doesn't account for microclimates or water/sunlight. Stay informed about local climate trends to select plants wisely.
While the USDA hardiness zone map is a useful tool for determining the minimum winter temperatures that a plant can survive in a given area, it has its limitations. The map is based on historical data and cannot predict future climate conditions or provide information on when to plant or sow seeds. It also does not account for microclimates or the amount of water or sunlight a particular area receives. So, while it can help gardeners choose plants that are likely to thrive in their region, it should not be the only factor considered when planning a garden. Additionally, as climate change brings more extreme weather, the map may not accurately reflect the full range of temperatures a plant may experience in a given area. Therefore, it's important for gardeners to consider multiple factors when selecting plants and to stay informed about local climate trends.
Considering Factors Beyond Hardiness Zones for Perennial Success: When selecting and caring for perennials, consider factors like sunlight, water availability, wind exposure, and the duration of cold in addition to hardiness zones.
While the hardiness zone map is a useful tool for understanding a plant's ability to survive winter temperatures, it does not provide information about summer heat. When planning and planting perennials, other factors such as sunlight, water availability, wind exposure, and the duration of cold should also be considered. For instance, plants in pots are more susceptible to extreme temperatures and wind, while those in the ground with deeper roots are better protected. Additionally, some plants require a cold period to set fruit, and warmer areas may allow for the growth of citrus instead of apples. It's important to consider these factors in addition to the hardiness zone when choosing and caring for perennials.
Choosing Plants for Your Garden: Consider Local Climate and Hardiness Zone: Research local climate and hardiness zone, consult experts, and choose plants well-suited to your area and experience level.
When it comes to gardening and choosing plants for your garden, it's important to consider the local climate and hardiness zone. Established plants may be able to survive brief exposure to cold weather, but it's crucial to ensure that the plants you purchase from reputable sources, such as local garden centers or nurseries, are suitable for your area to minimize the risk of failure. For beginners, it's recommended to start with tried and true varieties to build confidence and success in gardening. However, for those feeling more adventurous, consulting local botanic gardens and nurseries can provide valuable insights into what plants may thrive in unique situations, as experts and nursery owners are often experimenting with new varieties to offer the widest possible selection. Ultimately, the key is to do your research, consult local experts, and choose plants that are well-suited to your climate and gardening experience level.
Local botanic gardens and nurseries: valuable resources for home gardeners: Home gardeners can expand their plant selection by utilizing local botanic gardens and nurseries for expertise on plant hardiness zones and climate adaptations.
Local botanic gardens and nurseries have extensive knowledge about various plant species due to their extensive plant-killing experience. This knowledge is crucial for home gardeners looking to experiment with new plants based on their hardiness zones. The USDA hardiness map is a valuable tool to help determine which plants may survive the winter in a specific area, but it's essential to note that hardiness zones can change, potentially allowing for a wider range of plant options. Gardeners can mitigate the risk of trying new plants by taking precautions such as bringing potted plants inside or wrapping them in blankets during unseasonably cold winter nights. Overall, local botanic gardens and nurseries serve as valuable resources for home gardeners looking to expand their plant selection and adapt to climate change.
Supporting local journalism for a healthy democracy: By donating to organizations like NPR, we can help preserve local journalism and ensure access to accurate, unbiased news coverage, strengthening our democracy.
The health of local journalism in the United States has been declining over the past few decades, with about a third of newspapers disappearing and thousands of local journalists losing their jobs. This trend is concerning because a functioning democracy and a vibrant local news media are closely interconnected. NPR's Consider This podcast encourages listeners to support local journalism and keep the NPR network strong. By doing so, we can ensure that we continue to have access to accurate, unbiased, and essential news coverage that keeps us informed and engaged in our communities.
