The Best Pear Cultivars for North Dakota
Pears are one of the most delectable fruits you can grow in your backyard. The fruits are great for fresh eating 和 canning. A spectacular bonus of growing pears is the display of pure white blossoms in springtime. 这绝对是惊人的!
The keys to success for growing pears in our state include proper site selection, 选择耐寒品种, training the branches to avoid upright growth, 监测火疫病.
Pear blossoms are sensitive to frost injury. Avoid planting the trees in frost pockets. Mulching with wood mulch can help to insulate the soil, 导致缓慢的, gradual warming 和 preventing premature bud break.
The branches of pear trees often have an upright habit. Annual pruning/training 和 the use of branch spreaders can maintain more horizontal, 更强的, 枝繁叶茂.
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 和 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 和 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普通的). These varieties with relatively large, teardrop-shaped fruits will not be hardy in the northern part of our state. 乌苏里梨(Pyrus ussuriensis), which include ‘保证’ 和 ‘金色的香料’ are hardier. 亚洲梨(Pyrus pyrifolia)在北达科他州不耐寒.
