This is due to guttation.
Guttation is the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses/ banana leaves.
At night, transpiration usually does not occur, because most plants have their stomata closed. When there is a high soil moisture level, water will enter plant roots, because the water potential of the roots is lower than in the soil solution. The water will accumulate in the plant, creating a slight root pressure. The plant gets rid of excess water through water stomata called hydathodes.
Hydathodes are structurally modified portions of leaf which are meant to send out excess amount of water in a liquid form. . The process can be noticed early in the morning when one sees waterdroplets present at the tips or margins of leaves of plants that grow mostly in moist places.
. Guttation is not to be confused with dew, which condenses from the atmosphere onto the plant surface.
