PROBLEM TO BE SOLVED: To provide a planting kit comprising natural turf, with which natural turf can be easily planted on the building rooftop or the like, and to provide a method for planting the turf. SOLUTION: This planting kit comprises a planting tray 2 having ventilation clearance 5 formed below its bottom surface because of having legs 4, and multiple drainage/ventilation openings 7 at the bottom part, a clearance-forming member 12 made by joining a water-permeable sheet 14 on a rugged plate having multiple projections 13b on a base plate 13a, and laid on the inner bottom of the planting tray 2 to form clearance for water-flow and air-ventilation on the whole surface of the inner bottom part of the planting tray 2, a root- proofing sheet 16 put on the clearance-forming member 12 to let water pass therethrough but inhibit the roots of turf from getting therein, a raising base material 17 to be put on the roof-proofing sheet so as to plant the natural turf, and a net-like plate 20 laid together with the raising base material to disperse load given by the planted turf.
