The invention relates to a method, as well as to an apparatus, for separating bulbous or tuberous plants from loose pollutants which are present between the plants after harvesting. To this end, the bulbous or tuberous plants are brought in a trough with a liquid mixture or suspension, whose density is between that of the bulbous or tuberous plants and the pollutants to be separated. The bulbous or tuberous plants will keep floating on or near the surface, and the pollutants, at least the most part thereof, will settle within a relatively short time. The liquid mixture or suspension is preferably formed by mixing water prior to and during use with a part of the pollutants to be separated. The settled pollutants are removed from the trough via discharge means provided for that purpose and preferably dumped back onto the site where the bulbous or tuberous plants have been harvested.
