Quinces are seldom grown for their fruit these days, the chief use being as a stock for grafting pear trees ; for this purpose they are raised in vast quantities by nurserymen.
A light soil with an ample supply of moisture is best for quinces, and a full-grown tree 15 ft. to zo ft. high is a lovely sight in flower.
The fruit should be left to ripen late on the trees : they do not keep very long and are easily bruised. November is the usual time for gathering the fruit.
Some varieties of quince are called apple-shaped : these have large golden yellow fruits rather like an apple. Champion is an American variety of this type and is a vigorous grower.
The pear-shaped quince is another type which is usually grown as an ornamental tree ; it produces a large crop, but the flavour is inferior to the apple-shaped variety.
Portugal quince produces a smaller crop than the others, but the fruits are larger and have a better flavour ;it is particularly suitable for culinary purposes and turns red when cooked.
