Pears for North Dakota

Tips and cultivars for growing pears in North Dakota.

Pears are one of the most delectable fruits you can grow in your backyard. The fruits are great for fresh eating and canning. A spectacular bonus of growing pears is the display of pure white blossoms in springtime. It is absolutely stunning!

The keys to success for growing pears in our state include proper site selection, selecting hardy cultivars, training the branches to avoid upright growth, and monitoring for fire blight.

Pear blossoms are sensitive to frost injury. Avoid planting the trees in frost pockets. Mulching with wood mulch can help to insulate the soil, leading to a slow, gradual warming and preventing premature bud break.

The branches of pear trees often have an upright habit. Annual pruning/training and the use of branch spreaders can maintain more horizontal, stronger, more fruitful branches.

Fire blight is the leading killer of pears. This bacterial disease is introduced into the tree through wounds; often created by hailstorms or improper pruning. The initial symptoms will be scorched branch tips. Keep your eyes open for this disease and prune it out when you see it. The “ugly stub” treatment is often used for removing fire blight-infected branches.

Pears are best harvested before they are mature but not yet fully ripe. Mature pears are firm and will easily come off the branch when they are twisted upwards. Harvested pears will ripen fully off the tree when stored during a week of temperatures in the 60s.

The species of pears you select is important. Many of us are familiar with the ‘Bartlett’ pear (Pyrus communis). These varieties with relatively large, teardrop-shaped fruits will not be hardy in the northern part of our state. Ussurian pears (Pyrus ussuriensis), which include ‘Ure’ and ‘Golden Spice’ are hardier. Asian pears (Pyrus pyrifolia) are not hardy in North Dakota.

The varieties listed below are hardy only in Zone 4 unless noted otherwise. They are listed in order of ripening. Two compatible varieties are needed for good yields.
