Quince (Cydonia oblonga) trees grow best in U.S. Department of Agriculture zones 5 through 9. They produce an aromatic, golden-yellow fruit that is good for making jellies.
Quince trees thrive when planted in fertile soils in sites where they will receive full sun. Although they can withstand wet soils to some degree, they produce better in locations with good drainage. They also don't respond well to rapid changes in temperature and should therefore be planted in protected areas such as southern exposures next to wind breaks.
Fruiting quince trees rely on cross-pollination for fruit production, which means that more than one plant must be present for fruiting to occur. Fruit is ready for harvesting when it turns a bright golden yellow.
