How to Grow a Pear Tree Indoors for Perfectly Sweet and Juicy Fruit

Pear trees are a wonderful addition to your garden. Their fruits are an excellent source of dietary fiber and other nutrients, and they can be baked, grilled, or eaten fresh. However, not everyone is fortunate enough to live in an ideal growing zone for these trees.

Fortunately, there's a solution—they can be grown indoors. If you select the right variety and grow it carefully, a pear tree can thrive even in a living room. Here, we spoke to experts about how exactly to do it.

Best Indoor Varieties

If you want to grow a pear tree that produces fruit indoors, then it’s best to choose dwarf varieties. “Avoid cultivars that aren't self-fertile, as they’re more labor intensive,” says Nastya Vasylchyshyna, resident botany expert at Plantum. “They require pollen from a different pear cultivar that blooms at the same time in order to produce fruit."

Vasylchyshyna recommends the following varieties for indoor growing:

• Conference: You can prune this self-fertile cultivar to a height of 6.5 to eight feet, and it will produce large, juicy, sweet fruit.
• Williams: A self-fertile cultivar that remains compact with regular pruning. It yields delicious fruit with a slightly musky flavor.
• Durondeau: A partially self-fertile cultivar, meaning it can produce a few sweet fruits on its own. However, it needs a pollination partner to produce heavily.

How to Plant

Start by purchasing a healthy young tree—preferably on a dwarf rootstock—from a nursery. “Plant it in late winter or early spring while it's still dormant,” Vasylchyshyna says. “Choose a container that’s twice as deep and wide as the plant’s root system, and make sure the container has drainage holes to avoid waterlogging.” 

Place a layer of drainage material at the bottom of the pot, then fill the container with high-quality, loose, nutrient-rich and well-draining soil that has a pH level of about 6.0 to 7.0. 

“Move the tree to a cool, well-lit area—a balcony should work,” Vasylchyshyna says. “Protect the plant from cold drafts and freezing temperatures.” 

Dormant Periods

Fruit trees grown in a container still need a dormant period. However, your pear tree might not go dormant indoors, which may affect its overall health and its fruit production.

“Place your pear tree outdoors for a period of time to allow it to go dormant if it's failing to thrive,” advises Lisa Tadewalt, an ISA-certified arborist and co-founder of Urban Forest Pro

Care Instructions

An indoor pear tree requires more attention than a typical houseplant, especially if you want it to yield fruit. “You'll need to put in some extra effort and create the right conditions based on the tree’s growth stage,” says Vasylchyshyna.

Temperature

Having a spacious balcony or outdoor space is an important factor, as it needs a rest period in a cool place. “Otherwise, the plant won’t be able to form flower buds,” says Vasylchyshyna. “Keep in mind that you’ll need to provide the tree with a temperature around 30 to 42 degrees Fahrenheit for at least two to six weeks, depending on the cultivar.”

Sunlight

Pear trees prefer bright light, so it’s best to place yours on a south, southeast, or southwest-facing balcony. “In summer, move the container outside to a sunny spot that isn’t exposed to drafts, if possible,” says Vasylchyshyna.

Pruning

Don’t forget to prune the pear tree annually during winter dormancy to keep its goblet-like shape in check. “Remove any old shoots, along with weak, crossing, or inward-growing branches,” Vasylchyshyna says. “Leave only four or five strong scaffold limbs, which will produce fruit next season.”

When pruning the tree, use clean pruning shears. “Remember to disinfect the tool with rubbing alcohol or a bleach solution before and after using it,” she says. “Keep the shears sharp to avoid damaging the branches.”

Fertilizer

During active growth, feed the plant with a fertilizer formulated for fruit trees. “When applying the product, strictly follow the instructions on the packaging, without exceeding the recommended dose,” Vasylchyshyna says.

Other Conditions

Pay attention to the following conditions too: 

• Pot size: Use a pot that's at least 18 inches wide and has drainage holes, says Tammy Sons, founder and CEO at TN Nursery.
• Soil: Fill it with a loamy, nutrient-rich, well-draining potting soil, then mix in some compost. Plant the tree at the same depth it's currently growing in its nursery pot.
• Watering: Water when the top inch of soil is dry to the touch, and fertilize monthly in the spring and summer. When the tree is dormant in winter, water sparingly and infrequently. Be careful not to overwater, as this may cause rot and fungal diseases.

Fruit Production

To speed up fruiting, it’s a good idea to buy a healthy young tree from a nursery. “However, even with a strong sapling, it can take anywhere from four to 10 years before the first flowers and fruit appear,” Vasylchyshyna says. “This depends on the cultivar, the sapling’s age, and its growing conditions. So be prepared to wait, and allow the tree time to mature naturally.”

Harvesting

Ripe pears have a relatively short shelf life, especially those that ripen in late summer or early fall. “Once harvested, it’s a good idea to keep ripe fruit in the fridge and eat it within one to two weeks, or process it into sauce or jam,” Vasylchyshyna says.  

Some pear cultivars continue to ripen and sweeten after being picked. “Consider asking a specialist at the nursery about the best harvesting time for your cultivar so you can enjoy your fruit to the fullest,” she says.
