Apparatuses and methods for collecting and irrigating water for plant growth in dry regions. Exemplary apparatus has appearance of a plant having leaves and stems, and operates same way plants grow and irrigate rain water and/or dew. Includes at least one water harvesting device for condensing moisture in air and collecting yield water. Device includes: a) at least one device- body having a hydrophobic shell, and an internal-body-core surrounded by and enclosed within the hydrophobic shell； and b) plurality of condensation-protrusions disposed on the hydrophobic shell, each having internal-core and hydrophilic-shell surrounding and enclosing internal core. Device-body internal-body-core, in an integral manner, continuously extends to device-body hydrophobic shell and into (within) hydrophilic shell of each condensation-protrusion. When condensation-protrusions are cooler than moist air, hydrophilic-shell condenses and extracts moisture from air, becoming harvested water. When hydrophilic-shell is saturated, water flows on hydrophobic shell surface, and irrigates flowing water towards at least one target location.
