The old 2012 map, seen here, isn't as detailed or regional as the new plant hardiness map, in large part to the 2023 map including data from many more weather stations.
For example, we checked the report for Indianapolis and were told the spring window to plant tomatoes was from April 27 through May 11, while the report for Phoenix told us to plant them from Feb ...
For practical purposes, Canada has adopted the American hardiness zone classification system. The 1990 version of the USDA Plant Hardiness Zone Map included Canada and Mexico, but they were removed with the 2012 update to focus on the United States and Puerto Rico. [8] The Canadian government publishes both Canadian and USDA-style zone maps. [37]
According to the Köppen climate classification system, Towamencin is located in zone Dfa, indicating a humid continental climate with hot summers. [25] [26] Its USDA plant hardiness zone is 6b, except in some lower areas where it is 7a. [27] The warmest month is typically July, with an average maximum temperature of 85.7 °F (29.8 °C). [28]
Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand.
In the United States, the EPA and the United States Geological Survey (USGS) are the principal federal agencies working with the CEC to define and map ecoregions. Ecoregions may be identified by similarities in geology , physiography , vegetation , climate , soils , land use , wildlife distributions, and hydrology .
Zoning is a law that divides a jurisdiction's land into districts, or zones, and limits how land in each district can be used. [1] [2] In the United States, zoning includes various land use laws enforced through the police power rights of state governments and local governments to exercise authority over privately owned real property.
