Propagate quince through seed sowing, cuttings, or rootstock grafting. For seeds, stratify before planting in fertile, well-drained soil. Cuttings, preferably semi-hardwood, root in a shaded, humid environment. Grafting is effective for cultivar consistency. Optimal temperature is 20°C-25°C, with partial to full sunlight. Grafting can be intricate and requires skill. Steps: 1. Choose propagation method; 2. Prepare materials; 3. Plant seeds post-stratification or insert cuttings into rooting medium; 4. For grafting, join scion to rootstock; 5. Maintain appropriate moisture and light exposure; 6. Allow for establishment and acclimatization.
