While the domestic pear is hardly missing in an orchard, the Nashi pear is still a true exotic there. The fast-growing and robust Asian pear is easy to cultivate and, with appropriate care, consistently high yields can be expected. Under the mostly thin skin of the small, spherical fruits there is a juicy and aromatic pulp. The taste of the small vitamin bombs is reminiscent of pears, apples and melons.

Asian pears taste raw and can also be used to make jams or bake fruit pies. If you feel like bringing this little exotic into the orchard, you can find out everything you need to know about caring for the apple and pear here.

Pour the nashi pear properly

Nashi pears are quite robust and do not need to be watered continuously. Water and nutrient requirements are usually higher during the growing season. So that strong fruit can develop, the Nashi pear should be watered regularly, especially during longer periods of drought. Rainwater can preferably be used for this. Tap water is less suitable because it often contains too much lime.

" Tip: During the cold season, the Asian pear sheds its leaves and requires very little water.

In short:

  • Irrigation advisable during dry periods
  • water regularly during the growing season
  • Soil should not dry out
  • preferably use rainwater

How to fertilize properly

It is generally not a must to regularly fertilize the Nashi pear. If the trees are planted outdoors, the hobby gardener can meet the nutrient requirements of the plants by loosening the soil and adding compost or horn shavings. During flowering, fertilizers can help increase crop yield. Liquid fertilizer can be dosed well. Watch out for an overdose that could harm the plant. From August at the latest, fertilizers should no longer be administered, and then the plant prepares for hibernation. If fertilization continued, the new shoots would not develop sufficiently until winter and frost damage would result.

In short:

  • Enrich potting soil with organic fertilizer
  • use fertilizer sparingly during the growth phase
  • completely stop fertilizing from late summer

Cut the nashi pear

Various cutting measures are included in the care of the apple and pear, which will now be explained in detail.

❍ Cut back for higher yields

In order for the inflorescences to develop well and nothing stands in the way of a rich harvest, regular pruning is necessary. Young plants are already cut in their first year of use. For this purpose, all fresh shoots are shortened to a length of about one meter. With older plants, all shoots should be cut to about half each year. This promotes new shoots and flower formation. Pruning can be done in spring and autumn.

❍ Care cut for regular beauty treatments

So that the tree keeps its shape and remains an eye-catcher in the orchard, you should occasionally use scissors and shorten long and hanging shoots.

" Tip: Also remove the fruits, they stay very small anyway and taste less sweet.

A maintenance cut can be done all year round. Nashi pears tolerate pruning without problems. With a maintenance cut, you not only ensure an attractive appearance of the plants, the goal should also be to provide the inflorescences with as much sun as possible.

❍ Top cut for that special look

A tree is not a tree. The nashi pear can also be turned into a special eye-catcher when you use the scissors. If the shape cut is to be aimed for, the cut can be started in the first year of standing. Popular shapes are the hollow crown or the pyramid.

Detect diseases and pests in the Nashi pear

Parallels with the native pear fruit can also be seen in terms of pest infestation and the occurrence of diseases. However, the Nashi pear turns out to be far more robust than our common pears in the orchard.

Diseases can occasionally occur:

  • Pear rust
  • Canker
  • fire blight

The following was observed in pest infestation:

  • Birnengallmücke
  • Birnblattsauger

❍ Pear grid

The fear spreads in the orchard when the wind in spring carries the mushroom spores from the frequently infested juniper and deposits them on the leaves of the pear trees. Infestation is shown by reddish spots on the leaves. Later, the fungus works its way through the entire leaf and, if left untreated, the entire tree can shed the leaves. There is hardly any infection on the apple-pear. The sturdy Asians seem almost immune to pear grids.

❍ fruit tree cancer

The Nashi pear is less robust against fruit tree cancer. The fungus first appears in the form of a brownish-colored and dry tree bark. Round reddish spore deposits can still be seen on the trunk. Younger plants whose stem is not yet sufficiently developed are particularly at risk. If the fruit tree cancer is noticed, all affected parts of the plant must be cut back generously.

Fruit tree cancer is considered aggressive and can only be combated using chemical pesticides.

" Tip: Infested parts of plants that have been cut off must not be disposed of in the compost, as the fungus can spread there.

❍ fire blight

Fire blight is a bacterial disease often found in pear trees. At first the leaves and flowers wither, later they take on a black-brown color and appear as if burned. Young plants are also particularly at risk here and if left untreated, the nashi pear shrinks completely after about three weeks. If older plants are infected, they can survive for several years. If fire blight is noticed, you should react quickly and cut back all infected parts of the plant generously and down to the healthy wood.

❍ Pest attack on the Nashi pear

Pests are also extremely rare in the Asian pear. An infestation with the pear gall mosquito was observed. This lays its eggs on the fruit and the maggots of the gall mosquito feed on the pulp. Affected fruits must be disposed of.

The pear-leaf sucker is targeting the shoot tips. The eggs are laid directly in the shoot tips. A sooty dew reminiscent of honey is excreted from the larvae. This forms the basis for fungal diseases. If you notice an infestation, all affected shoots should be generously cut back and burned or disposed of with household waste.

What should be considered when wintering the Nashi pear?

Nashi pears have an exotic name, but are almost perfectly adapted to our climate. Trees cultivated in the open are not affected by severe frosts of -20 degrees. No winter protection is required.

Restrictions have to be made for young plants. The sensitive root system can be protected by a mulch layer in the first years of standing. When it comes to keeping pots, the roots are less robust and are easier to attack. It is advisable to cover the ground with leaves or brushwood, to place the tub on a wooden or polystyrene support and to assign the tub plant a protected location, for example on a house wall.
