We are still encouraging people to plant trees, including fruit trees, medicinal plants. Planting trees is the best protection for the environment, and therefore, whatever trees we plant, we must take care of them. Malagasy trees are green, humid all year round and suitable for maintaining the environment. The maintenance of the planted trees begins with fire protection, then the addition of fertilizer, without forgetting to water as much as possible, using a perforated "plastic" bottle, so that it is the drip that moistens it.
