Harvest Tips
Harvest fruits in fall when fully mature and yellow-green, typically September-October. Fruits can be left on plant into winter for ornamental effect. Pick fruits when they feel slightly soft to pressure. Use immediately or store in cool conditions. Wear gloves as branches are thorny. Cut rather than pull to avoid damaging branches.
Fun Facts
- 🌱 Japanese quince is one of the first shrubs to bloom in spring, often flowering before forsythia, and ancient cultures believed the fragrant blooms symbolized renewal and good fortune.
- 🌱 The fruits are so hard and astringent that they cannot be eaten raw, but they contain higher levels of pectin than most apples, making them ideal for jellies that set naturally without added pectin.
- 🌱 Japanese quince has been cultivated for over 1,500 years and is associated with early spring celebrations in Japan; some varieties are selected specifically for their ornamental form rather than fruit production.
