The Asian pear tree (Pyrus pyrifolia) is part of the Rosaceae family, which includes fruit trees such as plums and peaches. The Asian pear produces copper-colored, rounded fruits that are a few inches long. The fruits are juicy like a pear but crunchy like an apple—hence the reason they are sometimes referred to as “papples.” They can be eaten raw or cooked. The tree features dense green foliage in a pyramidal or rounded shape. The foliage turns a red or burgundy color in the fall. And showy cup-shaped flowers appear in the spring that stretch around one to three inches across. This tree has a fairly quick growth rate and is best planted in the spring after any danger of frost has passed.

How to Plant Asian Pear Trees
About one week before planting, remove weeds, grass, and rocks from the site. Pull apart any soil clumps. If you're planting more than one tree, space them at least 15 feet apart. Before planting, soak the tree's roots in a large container of water for about one hour. Dig a hole twice as deep and wide as the root ball, so the roots will fit and spread freely in the ground. Mix a four-inch layer of compost into the soil.
Cut any damaged roots off the root ball and loosen the roots. Place the tree in the hole at the same level as it was in the original pot. Backfill with two-thirds of the soil, and then gently tamp the soil. Before backfilling with the last third of the soil, soak the soil with a garden hose. Let the hose trickle water slowly, so the soil can absorb the moisture.
Make sure there's no soil depression around the base because in winter water can accumulate there, freeze, and damage the tree. Establish a 10-foot-tall stake two feet deep into the ground and four inches away from the trunk. Tie the tree to the stake to keep it growing straight.
Asian Pear Tree Care
The Asian pear tree grows best in full sun, meaning at least six hours of direct sunlight on most days. Find the most open and sunny area of your garden where there's good airflow.
These trees prefer rich soils with good drainage. Loam or a sandy loam is best, though they also can tolerate clay if it's not too dense to drain. A slightly acidic to neutral soil pH is ideal. One year before planting, test the soil pH. If it needs to be increased, add lime into the top seven inches of soil. If it needs to be decreased, add sulfur. Contact your local county extension service about conducting a soil sample.
Lightly moist but not soggy soil is ideal for Asian pears. Water the tree deeply to maintain even soil moisture after planting. Water established trees when the top inch or two of soil have dried out. Adjust watering times based on rainfall and hot weather.
Temperature and Humidity
Asian pear trees are cold-hardy, and they need a chill period over the winter where temperatures are below 45 degrees Fahrenheit for at least 50 to 70 days. Otherwise, they won’t produce blossoms and fruits as profusely. They also require summer heat to develop their fruits. However, make sure their moisture needs are being met, especially in very hot weather. A moderate humidity level is ideal.
Wait a month after planting before fertilizing. Then give the tree a half-pound of 10-10-10 fertilizer. If the tree ends up growing more than one foot per year, refrain from fertilizing it. Nitrogen encourages growth, but too much can prevent optimal fruiting or encourage diseases. If the tree grows slowly (fewer than eight inches each year), feed it a third to a half cup of 10-10-10 fertilizer per every year of the tree's age.
Spread a four-inch layer of bark mulch over the tree's root zone starting four inches away from the trunk. Add part of the layer in the spring before new growth appears and the second portion when the tree begins fruiting. Maintain a two to four-inch layer of mulch to keep weeds down and retain soil moisture. Adding compost or farm manure in spring and summer can also promote healthy growth. Before winter starts, mulch again with straw or grass.
Asian Pear Tree Varieties
There are many varieties of Asian pear trees, including some dwarf cultivars that reach only around eight to 15 feet tall. Popular varieties include:
- 'Chojuro': This cultivar produces fruits that have somewhat of a butterscotch flavor.
- 'Niitaka': This tree features yellow fruits that resemble apples.
- 'Shinseiki': This cultivar is known for bearing a high volume of fruit.
- 'Hosui': This cultivar produces golden fruits and is known for being one of the best-tasting Asian pears.
Expect your first Asian pear harvest in the tree's second or third year. Harvest when the fruit color changes to yellow or copper-green with tiny caramel-colored flecks. This will occur in the late summer to fall, depending on variety and climate. Some fallen fruits around the tree are also a sign that the pears are ripe and ready for harvesting. Ripe pears will come off the branches easily.
You can keep the pears at room temperature for about a week or in the refrigerator for roughly two to three weeks. Handle them with care, as they bruise easily.
Prune your tree over the winter while it’s dormant. Young Asian pears will likely need pruning to encourage a good shape. And mature trees will need pruning to remove any dead, damaged, or overgrown branches. Thin the canopy by about 10 to 20 percent, removing branches that are crossing or growing at odd angles. This will improve air circulation and allow sunlight to hit all parts of the tree. Remove diseased branches as they arise.
Common Pests and Diseases
Protect fruits with nets to prevent birds and wasps from eating them as they develop. Also, keep an eye out for common garden pests, including aphids and caterpillars. Asian pear trees can also suffer from fungal pear rust and other diseases common to apples and pears.
