What task does an interior decorator not typically perform?

An interior decorator does not typically engage in the task of collecting soil samples. This activity is more aligned with fields such as landscaping or environmental science, where understanding the ground composition is essential for making informed decisions about plant selection and site preparation. In contrast, interior decorators focus on enhancing indoor spaces through design elements, color schemes, furniture selection, and decor that align with a client's vision. They are experts in creating aesthetically pleasing and functional environments, which involves tasks like designing interior layouts, choosing furniture and decor, and consulting with clients to understand their needs and preferences. Therefore, collecting soil samples is outside the purview of an interior decorator's responsibilities.
