What Hardiness Zone is Kansas City Mo In: Understanding Plant Hardiness Zones

What Hardiness Zone is Kansas City Mo In

A hardiness zone map is a standard guide developed by the United States Department of Agriculture. The map divides different areas of the country into 10-degree Fahrenheit zones based on the average minimum winter temperature. Typically, the lower the zone number, the lower the temperatures in the zone. Therefore zone 1 is the coldest, whereas zone 13 is the hottest. This information is vital to growers and gardeners as it helps them identify plants that are most likely to thrive in their area.

Hardiness zones are subject to change. Currently, trends indicate that hardiness zones in the U. S. are moving towards the north at 13 miles every decade. This means that the average minimum temperatures in winter shift by half a zone warmer since the last review in 1990.

Difference between plant hardiness zones and climate zones.

Both hardiness zones and climate zones geographically divide areas according to the climate. However, hardiness zones help in determining where certain plants will thrive. On the other hand, climate zones divide the earth according to climate, average temperature, vegetation, and air pressure. These four main zones are; temperate, tropical, subtropical, and arctic.

Kansas City Hardiness Zone

Kansas City is known to experience pretty warm temperatures in the summer and lows of up to 0 to 10 degrees in the winter. Although the area is considered zone 6, some gardeners and horticulturists remain somewhat reserved on the type of plants to go for and prefer to work with zone 5 plants instead. There is an undeniable controversy over whether Kansas City lies on either zone 5 or 6, causing a disparity between the USDA map and current maps such as the Arbor Day Foundation map. The differences are attributed to the age of data used; the USDA still uses decades of data, whereas today’s mappers use more short-term and recent data.

Additionally, winters in the area appear to grow colder, pushing Kansas City closer and closer to zone 5. The weather also takes a swift shift from hot to cold-causing wild transitions in temperature, which often results in winter plant damage in the area. This means farmers and gardeners have a lot of homework to do with regard to identifying resilient plants to withstand swift changes.
