Really? Not free draining bonsai stuff?
Quinces tolerate a range of soils, but grow best in a deep, fertile, moisture-retentive soil. They grow particularly well when planted near a pond or stream, but dislike waterlogging in winter. In light or shallow chalky soils, add plenty of organic matter before planting and mulch well afterwards.
