Quince is a relative of apples and pears with lumpy, fuzzy yellow fruit whose strong perfume can scent a room. Slow cooking turns it into membrillo (quince paste), jelly and poached fruit. Its big pale pink spring flowers make it an ornamental tree too.

An old-fashioned small tree with big, fragrant yellow fruit that's too hard to eat raw but turns pink and perfumed when cooked. It's self-fertile, so one tree is enough. Leaf blight is the main trouble in wet west-side springs.

How to grow quince trees

  1. Pick a sunny spot with soil that drains well, and mix in an inch or two of compost.
  2. Plant quince trees on your city's dates, 12 to 15 feet apart. Same depth as in the pot or nursery.
  3. Water deeply through the first two summers. Prune lightly in late winter to open up the center.
  4. Harvest: Pick in October when the fruit turns from green to fully yellow and smells strongly fragrant. Handle gently; they bruise easily. Cook them into jelly, paste or poached fruit.

Growing quince trees in your part of the Northwest

The same plant behaves differently on the wet west side, the foggy coast and the dry, colder east side.

West-side valleys

Willamette Valley, Puget Sound, southern Oregon

Quince is easy in west-side gardens. Fire blight and leaf blight are the main diseases in wet springs.

How much to grow

How many to plant

One tree is enough; quince is self-fertile.

What to expect

A mature tree gives roughly 30 to 60 pounds.

Storing the harvest

Keep in a cool, dark place for two to three months. The scent fills a room.

Key numbers

Top care tip: Rake up and remove fallen leaves each autumn to cut down on leaf blight.

Growing notes

What makes the difference in Northwest gardens, in plain language.

What quince is

Fruiting quince, Cydonia oblonga, is a small tree related to apples and pears, with big pink-white spring flowers and golden, fragrant fruit in fall. It's not the same as flowering quince, an ornamental shrub with small, hard fruit.

Most varieties are too hard and sour to eat raw. Cooked slowly, the flesh turns pink and perfumed, which is why quince is prized for jelly, paste and poached fruit. Aromatnaya is one of the few soft enough to eat fresh when fully ripe.

Planting and care

Quince is self-fertile, so one tree is enough. Plant in full sun in soil that drains reasonably well. It blooms late, after most frosts, and it's very cold-hardy.

Trees grow 12 to 15 feet and need only light pruning in late winter to remove crossing branches and open the center.

Diseases

Quince leaf blight is the main problem in wet west-side springs: brown spots on leaves and fruit and early leaf drop. Rake and remove fallen leaves in autumn and prune for good airflow.

Quince can also get fire blight. Cut blackened shoots well below the damage on a dry day.
