PROBLEM TO BE SOLVED: To provide an apparatus and a method for plant cultivation carrying out a local cooling to facilitate plant growth and fruit coloring with suppressed capital investment. SOLUTION: The invention relates to the plant cultivating apparatus supplying air with conditioned temperature and humidity from a tip of pipe fitting 11 into a bag 6 for fruit, for scattering the air to heat or cool the local point of the plant, wherein the conditioned air is obtained by introducing compressed air from a pipe fitting 9 to a vortex tube 10 and feeding warm wind and cool wind obtained by the vortex tube 10 into each flowing pipe fitting 17, 18 and adjusting the feeding rate of the warm wind and the cool wind and then mixing with a three-way valve 19, the apparatus inexpensively feeds the air with conditioned temperature and humidity to the local point of plant by the simple apparatus without necessitating heat-exchanger, etc., and facilitates coloring of grapes, etc., promote growth of plants, preventing disease, realizing a high quality cultivation of the plant in a district with more genial climate, and expansion of growing season to summer in plants cultured in winter in addition to the improvement of quality in cultivating in a district suitable for cultivating.
