These, in turn, affect transcription, translation, intermediate metabolism, and photosynthesis, leading to an energy imbalance. This energy imbalance is thought to be one of the ways the plant detects low temperature. Experiments on arabidopsis show that the plant detects the change in temperature, rather than the absolute temperature. [2]
An early light frost can wipe out your garden harvest for the season. When a light frost is expected, water your garden to wet the plants. So, a light water layer on your plants will help protect ...
Black frost (or "killing frost") is not strictly speaking frost at all, because it is the condition seen in crops when the humidity is too low for frost to form, but the temperature falls so low that plant tissues freeze and die, becoming blackened, hence the term "black frost".
Photograph taken 21 March 2010 in Norwich, Vermont. Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface, upwards from the depth in the soil where freezing temperatures have penetrated into the soil (the freezing front or freezing boundary).
Use a frost blanket: Cover plants, trees, and shrubs with frost blanket when temperatures drop. These blankets, available in materials like UV-resistant polypropylene fabric and natural burlap ...

Depending on the plant species, maximum freezing tolerance can be reached after only two weeks of exposure to low temperatures. [2] The ability to control intercellular ice formation during freezing is critical to the survival of freeze-tolerant plants. [3]
An individual tree can transpire hundreds of liters of water per day. For every 100 liters of water transpired, the tree then cools by 70 kWh. [2] [3] Urban heat island effects can be attributed to the replacement of vegetation by constructed surfaces. Deforested areas reveal a higher temperature than adjacent intact forest.
