'''Wilting''' refers to the loss of rigidity of non-woody parts of [[plant]]s. This occurs when the [[turgor pressure]] in non-[[lignin|lignified]] plant [[plant cells|cells]] falls towards [[zero]], as a result of diminished [[water]] in the [[cell]]s. The [[process]] of wilting modifies the [[leaf angle distribution]] of the plant (or [[canopy]]) towards more erectophile conditions.
Lower water availability may result from:
* [[drought]] conditions, where the [[soil moisture]] drops below conditions most favorable for plant functioning;
* high [[salinity]], which causes water to diffuse from the plant cells and induce shrinkage;
* saturated soil conditions, where [[root|roots]] are unable to obtain sufficient [[oxygen]] for [[cellular respiration]], and so are unable to transport water into the plant; or
* [[bacteria]] or [[fungi]] that clog the plant's [[vascular plants|vascular]] system.
Wilting diminishes the plant's ability to [[transpiration|transpire]] and grow. Permanent wilting leads to [[plant death]]. Symptoms of wilting and [[blight]]s resemble one another.
In [[woody plant]]s, reduced water availability leads to [[cavitation]] of the [[xylem]].
Wilting occurs in plants such as [[Balsam]] and [[tulasi]].

'''
Keep the wilted flowers in hot water of about 115-120 F temperature.Do not keep them in more hotter water as they may die.Do not keep the flowers which are not wilted in hot water.
