Predictive dormancy occurs when an organism enters a dormant phase before the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase after adverse conditions have arisen. This is commonly found in ...
Winter rest (from the German term Winterruhe) is a state of reduced activity of plants and warm-blooded animals living in extratropical regions of the world during the more hostile environmental conditions of winter. In this state, they save energy during cold weather while they have limited access to food sources.
They’re just dormant. “Dormant plants are alive,” said Sharon Yiesla, plant knowledge specialist at The Morton Arboretum in Lisle. “They’re just inactive.” Dormancy is a tactical ...
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous.

While houseplants do react to indoor conditions in your home in winter, they don’t actually go dormant. While growth may slow due to lower light levels in winter, that’s not universally true.
However, slowed growth isn’t always problematic and plants naturally grow slower in winter. Root rot. If your plant’s roots or stems are mushy and smelly, your plant may be affected by root rot .
The worst season to water outdoor plants is during freezing winter weather when temperatures can be below freezing. "Watering at this time can lead to water freezing around the roots or on leaves ...
Growing degree days (GDD), also called growing degree units (GDUs), are a heuristic tool in phenology.GDD are a measure of heat accumulation used by horticulturists, gardeners, and farmers to predict plant and animal development rates such as the date that a flower will bloom, an insect will emerge from dormancy, or a crop will reach maturity.
