PROBLEM TO BE SOLVED: To provide a plant management apparatus intended for promoting appropriate cultivation management through informing a user of a cultivation condition according to a raising environment of every plant. SOLUTION: This plant management apparatus 1a has a temperature detecting part 16, a humidity detecting part 17, and an illumination detecting part 18 which detect each kind of a detected value indicating the peripheral environment of a plant, a first memory part 11 which memorizes each kind of a detected value detected from the temperature detecting part 16, humidity detecting part 17, and illumination detecting part 18, and a CPU (Central Processing Unit) 10 which discriminates existence or nonexistence of abnormality in the cultivation condition of a plant and a problem tendency, based on each kind of a detected value detected from the temperature detecting part 16, humidity detecting part 17, and illumination detecting part 18, and previously fixed discrimination standard information. Furthermore, the apparatus has an indicating lamp 14 which informs the cultivation condition of a plant according to the discriminated result of the cultivation condition of a plant with the CPU 10, a rumbling part 15, and a first communication part 12 which sends each kind of a detected value memorized in the first memory part 11 to an external apparatus 2a, according to power supply generated by inductive electromagnetic field or electric wave supplied from the external apparatus 2a.
