We have to take a series of actions on the plants we grow before we can harvest them. Firstly, we have to feed them fertilizers to make the stem grow faster and bigger. Working together with some of the daily workers, we, the teachers and students, always carry out this process. Not only the fertilizers we need to feed the plants, we also need to use insecticide and pesticide on the plants. Usually, students’ parents help us in spreading pesticide and insecticide on the plants.
