When to plant pear trees

Plant in the garden: Portland and Seattle Mar 1 – Apr 26; Spokane Apr 1 – May 27; Boise Mar 20 – May 15; Bend Apr 28 – Jun 23.

Pear trees are long-lived fruit trees grown for buttery European pears like Bartlett, Bosc and Comice, eaten fresh, baked or canned. They bloom earlier in spring than apples. Oregon's Hood River Valley and Washington's Wenatchee and Yakima valleys are among the country's main pear-growing areas.

How to grow pear trees

  1. Pick a sunny spot with soil that drains well, and mix in an inch or two of compost.
  2. Plant pear trees on your city's dates, 12 to 15 feet apart for dwarf trees, 18 to 20 feet for standard. Graft union 2 to 3 inches above the soil.
  3. Water deeply through the first two summers. Pears need little pruning; take out crossing branches in late winter and keep the center open.
  4. Harvest: Pick European pears when they're full size and lift off easily but are still hard, then ripen them at room temperature. Asian pears ripen on the tree; pick when sweet and crisp.

Growing pear 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

Pear scab and fire blight are the main diseases in wet, mild springs. Cut fire-blighted shoots well below the dead wood in dry weather.

East of the Cascades

Columbia Basin, Yakima, Boise, Spokane, north Idaho

Hood River and the Wenatchee valley are major pear regions. Pear psylla and fire blight are the main problems; fire blight spreads fastest when warm spring rain falls during bloom.

High desert and mountain towns

Central Oregon, high eastern Oregon valleys, McCall, Salmon

Pears bloom early, so late frosts often take the crop. European pears are generally hardier than Asian pears here.

More pear varieties

More widely sold picks that do well somewhere in the Northwest. The tag says which part of the Northwest suits each one best.

Bartlett

European, best with partner · Ripens late August

The classic juicy, buttery yellow pear for eating fresh and canning. Pick it full size but firm and ripen indoors; it sets better crops with another pear variety nearby.

Both sides

Comice

European, needs partner · Ripens late September

Considered the finest-flavored pear, with sweet, melting, aromatic flesh. It needs a pollinator such as Bartlett and benefits from a few weeks of cold storage before ripening.

Both sides

Seckel

Small European dessert pear · Ripens September

Small, russeted pears with spicy, intensely sweet flavor, ideal for snacking and preserving. The tree is compact and has good resistance to fire blight.

Both sides

Shinseiki

Asian pear, partly self-fertile · Ripens August

Round, crisp, juicy yellow fruit that ripens on the tree. It bears young and heavily, and it also pollinates other Asian and many European pears.

Both sides

Bosc

European, russeted · Ripens September to October

Long-necked brown pears with dense, sweet, spicy flesh that holds its shape when baked or poached. It needs another pear for pollination and stores well.

Both sides

D'Anjou

European, long-storing · Ripens late September

Mild, sweet and juicy, with fruit that keeps in cold storage for months. Plant it with another pear variety for good crops.

Both sides

Chojuro

Asian pear, russeted · Ripens late August to September

Golden-brown Asian pears with a rich, almost butterscotch flavor and crisp texture. It stores well for an Asian pear and needs another Asian or European pear for pollination.

Both sides

How much to grow

How many to plant

Most European pears need a second variety that blooms at the same time. Asian pears can pollinate many European varieties.

What to expect

A mature semi-dwarf tree gives about 2 to 4 bushels.

Storing the harvest

Pick hard and keep in the fridge. Bartlett keeps one to two months; d'Anjou and Bosc three to five. Ripen at room temperature for a few days before eating.

Key numbers

Top care tip: Pick European pears when mature but still hard, then ripen them indoors at room temperature.

Growing notes

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

Choosing varieties that pollinate each other

Pears are some of the most forgiving fruit trees for west-side gardens: they tolerate heavy, damp soil better than most fruit trees and need little spraying. Most European pears need a second variety that blooms at the same time. Bartlett, Comice and Seckel can pollinate each other, though Bartlett and Seckel are a poor match. Asian pears like Shinseiki bloom early, but they often overlap enough with early European pears to help with pollination as well.

Choose a rootstock suited to your space. Dwarfing pear rootstocks still make fairly large trees, so leave room as guide spacing suggests.

Why European pears ripen off the tree

A European pear left on the tree ripens from the inside out and turns gritty or mushy at the core. Pick them when they reach full size and the stem snaps off with a gentle lift, while the flesh is still firm. Bartlett ripens at room temperature in about a week. Comice and Anjou-type pears ripen better after a few weeks in the refrigerator, then a few days on the counter. Check ripeness by pressing gently near the stem: when it gives, it's ready.

Pests and diseases in the Northwest

Pear scab works like apple scab and spreads from fallen leaves in wet springs, so rake leaves each fall. Fire blight is a bacterial disease that thrives in warm, humid weather during bloom; it's more common east of the Cascades. Prune out blackened shoots in dry weather, cutting 8 to 12 inches below the damage and wiping your shears with disinfectant between cuts.

West of the Cascades, pear trellis rust causes bright orange spots on leaves. It spends part of its life on junipers, so it's worse near juniper hedges, and it's mostly cosmetic.

  • Another pear variety. Cross-pollination.

  • Junipers close by. They host pear trellis rust, which spots pear leaves orange.

Pests and problems

What most often goes wrong with pear trees in Northwest gardens, how to spot it and what to do.

Pear scab

Signs: Dark spots on leaves and cracked fruit.

What to do: Rake up fallen leaves and choose resistant varieties.

Fire blight

Signs: Shoot tips blacken and curl like a shepherd's crook.

What to do: Cut 8 to 12 inches below the damage on a dry day and clean pruners between cuts.

Pear slug

Signs: Slimy, dark larvae skeletonizing leaves in summer.

What to do: Hose them off or dust leaves with fine soil or ash.

Common questions about growing pear trees

When should I plant pear trees in Oregon, Washington and Idaho?

Plant in the garden: Mar 1 – Apr 26 in Portland and Seattle, Apr 1 – May 27 in Spokane, Mar 20 – May 15 in Boise and Apr 28 – Jun 23 in Bend. Pick your town at the top of the page for your own dates.

Why are my pears gritty or brown in the middle?

They were left on the tree too long. European pears should be picked while still hard and ripened indoors. Pick when the fruit reaches full size and lifts off the branch easily.

Do I need two pear trees?

For most European pears, yes. Plant two varieties that bloom at the same time, such as Bartlett and Comice. A neighbor's pear tree nearby can also do the job.

How long can you store homegrown pears?

Bartlett keeps for a few weeks in the refrigerator, while Comice and other winter pears can keep for a couple of months. Bring them out a few days before you want to eat them so they can soften.
