do not tolerate rapid changes in temperature and exposure. Quinces bloom
rather late, providing them some frost protection.
Pollination.
Some quince varieties are reported to be entirely self-fruitful,
others partially self-fruitful, and others not self-fruitful. Recommendations
also vary from one authority to another. If you are unsure as to whether the
variety you select is self-fruitful, plant another variety within 50 feet to en-
sure fruit set.
Pests and diseases.
The greatest challenges in quince culture involve pests
and diseases. Cornell University reports that quinces were once widely
grown in New York, but flower bud injury due to winter temperatures, fire
blight, borers, codling moth, plum curculio, scale, and tent caterpillars led to
cutbacks in production.
Quinces can be grown organically, but they are more challenging than
some other tree fruits. It is very important to manage tree vigor by main-
taining low to moderate growth. Too much nitrogen or pruning can stimulate
lush, fire blight-susceptible foliage. Because quinces bloom rather late in
spring, weather at that time tends to be warm and humid, favoring fire blight.
Plan to use an aggressive pest and disease control program that may include
applications of antibiotics and beneficial bacteria during bloom.
Consumer demand.
Although quinces can be rather expensive in food mar-
kets, remember that consumer demand for these fruits is also low in most
parts of Canada and the United States. Washington State University reports
some commercial producers are having success marketing to niche ethnic
markets that favor Mediterranean cuisine. Markets in and near Mexico might
also provide opportunities, as quince (membrillo) is popular there.
Be sure you have thoroughly evaluated your market before moving heav-
ily into commercial quince culture. Customer education will be an important
part of your marketing, as relatively few people are familiar with the fruits
