PROBLEM TO BE SOLVED: To improve the dry spot of lawn grasses. SOLUTION: A water-retaining polymer pack (18) in which a water-absorbed, packed, water-retaining polymer is packed is set to a receiving cylinder (6). A manual handle (28) is operated to extrude the water-retaining polymer from an extrusion port and further spurt out the water-retaining polymer from a nozzle (3) connected to the extrusion port. The nozzle (3) is inserted into an underground water-repelling soil portion developing a dry spot (2), and the water-absorbed, gelled, water-retaining polymer is pressed into the water- repelling soil portion to directly supply the water to the portion. |
