The growing season is that portion of the year in which local conditions (i.e. rainfall, temperature, daylight) permit normal plant growth. While each plant or crop has a specific growing season that depends on its genetic adaptation , growing seasons can generally be grouped into macro-environmental classes.
Classification into spring wheat versus winter wheat is common and traditionally refers to the season during which the crop is grown. For winter wheat, the physiological stage of heading (when the ear first emerges) is delayed until the plant experiences vernalization , a period of 30 to 60 days of cold winter temperatures (0 to 5 °C; 32 to 41 ...
The agricultural growing season has also expanded by 10–20 days over the last few decades. [20] The effects of season creep have been noted by non-scientists as well, including gardeners who have advanced their spring planting times, [21] and experimented with plantings of less hardy warmer climate varieties of non-native plants.

Season extension in agriculture is any method that allows a crop to be grown beyond its normal outdoor growing season and harvesting time frame, or the extra time thus achieved. To extend the growing season into the colder months, one can use unheated techniques such as floating row covers , low tunnels, caterpillar tunnels, or hoophouses .
The chilling requirement of a fruit is the minimum period of cold weather after which a fruit-bearing tree will blossom. It is often expressed in chill hours, which can be calculated in different ways, all of which essentially involve adding up the total amount of time in a winter spent at certain temperatures. [1] [2]
With squishy black dirt from a relatively snowless winter, Minnesota farmers could have planted corn crops last month — but didn't. They wouldn't dare sow seeds before April 10, no matter how ...
Low pressure systems moving up the East Coast and through the Great Lakes, bring cold season precipitation to from the Midwest to New England, as well as Great Salt Lake. The snow to liquid ratio across the contiguous United States averages 13:1, meaning 13 inches (330 mm) of snow melts down to 1 inch (25 mm) of water. [1]
