A chilling unit in agriculture is a metric of a plant's exposure to chilling temperatures. Chilling temperatures extend from freezing point to, depending on the model, 7 °C (45 °F) or even 16 °C (60 °F). [3] Stone fruit trees and certain other plants of temperate climate develop next year's buds in the summer.
As with outdoor plants, overwatering in winter can lead to drowning the plant or root rot and fungal issues. Tips for Watering Plants the Right Way Keep these tips in mind when watering your plants.
Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.
In 2012 the USDA updated their plant hardiness map based on 1976–2005 weather data, using a longer period of data to smooth out year-to-year weather fluctuations. [7] Two new zones (12 and 13) were added to better define and improve information sharing on tropical and semitropical plants, they also appear on the maps of Hawaii and Puerto Rico.

World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
Plant growth has been observed to be correlated to the number of degree days. Many plants will fruit after a certain number of degree days. Common examples are strawberries and raspberries. In contrast, deterministic plants will fruit based on the time of year, which the plant determines from the number of consecutive hours of dark. Examples of ...
