A system for identifying and displaying one or more optimal locations within a lot for a garden in which to plant and grow suggested plant varieties is discussed. The system includes a robotic device positioned and configured to scan the lot and to generate at least one lot parameter. The system also includes a soil sensor positionable in soil in the lot and configured to generate at least one soil parameter. The system further includes a computing system configured to execute a location optimization module that determines varieties of suggested plants based on the soil parameter and the lot parameter. Based on a user selection from the varieties of suggested plants, the computing system identifies optimal locations for a garden within the lot for the one or more selected plants. The computing system transmits the optimal locations for the garden to a user computing device for display.
