Why? Under low transpiration and high soil moisture conditions, high root pressure of plants can secret water drops at the margin or tips of plant leaves through hydathodes, which is called guttation [15]. The formation of such droplets is called guttation. It isn’t dew, which tends to occur mostly outdoors when the air is humid and the night is cool. Only then guttation takes place.

How do you choose the right capillary mats? How to establish a nutritional feeding schedule? Increasing the root-bomb pressure increased the evaporation rate slightly when xylem pressure was negative and increased water flow rate through the shoots dramatically when xylem pressure was positive and guttation was observed. At worst, as the drop of sap dries, it may leave behind a white deposit (coming from minerals and sugars exuded along with the water) or a particle of dried black sap. The negative pressure exerts a pulling force on the water in the plant’s xylem and draws the water upward (just like you draw water upward when you suck on a straw). It’s unsightly, but not really harmful to the plant … and unless the damage occurs over and over, killing too many cells, in which case the leaf may be of little use to the plant, so it will shed it. Xylem sap will exude from the cut stem for hours or days due to root pressure. If you regularly see guttation, it’s possibly because you water too generously or something is keeping the soil’s moisture from draining away. This creates a pressure inside the plant, and the water is forced out through the hydathodes. Tomato, grasses, colochasia, cucurbita members, balsam, etc. Root pressure provides the impetus for this flow, rather than transpirational pull.
