Guttation is the exudation of drops of xylem and phloem sap on the tips or edges of leaves of some vascular plants, such as grasses, and also a number of fungi. Ancient Latin gutta means "a drop of fluid", whence modern botany formed the word guttation to designate that a plant exudes drops of fluid onto the outer surface of the plant, when the ...
The worst time of day to water outdoor plants is in the middle of the afternoon during hot and sunny weather. "During this time, the heat and sun cause water to evaporate quickly, reducing the ...
The plants may recover during the night when evaporation is reduced as the stomata closes. [2] In woody plants, reduced water availability leads to cavitation of the xylem. Wilting occurs in plants such as balsam and holy basil，and other types of plants. Wilting is an effect of the plant growth-inhibiting hormone, abscisic acid.
Plant saucers are meant to keep water from dripping on your floor, but it's best to empty out your saucers after watering so your plants aren’t sitting in water for a prolonged amount of time. 4 ...

Dew is water in the form of droplets that appears on thin ...
Available water capacity is the amount of water held in a soil profile available to plants. As water content drops, plants have to work against increasing forces of adhesion and sorptivity to withdraw water. Irrigation scheduling avoids moisture stress by replenishing depleted water before stress is induced. [64] [65]
The maximum amount of water that a given soil can retain is called field capacity, whereas a soil so dry that plants cannot liberate the remaining moisture from the soil particles is said to be at wilting point. [2] Available water is that which the plants can utilize from the soil within the range between field capacity and wilting point.
Interception [1] refers to precipitation that does not reach the soil, but is instead intercepted by the leaves, branches of plants and the forest floor. It occurs in the canopy (i.e. canopy interception ), and in the forest floor or litter layer (i.e. forest floor interception [ 2 ] ).
