Kieffer Pear Trees are easy to grow for several reasons. The trees are tolerant of both very cold winters and hot summers, they can take brief stretches of drought, and they are resistant to many pests and diseases that can affect other fruit trees. Mature Kieffer Pear Trees grow to twenty-five feet tall and fifteen to twenty feet wide. Their fruit is large, yellow, crisp, and juicy. The Kieffer Pear is a high quality fruit that is good for eating fresh or cooking.

The recommended areas for growing a Kieffer Pear Tree are within USDA Zones 4 to 9. This makes them great for warm areas such as the southern U.S. Kieffer Pear Trees prefer direct sunlight, rich but well-drained soil, and periodic water. The trees bloom in spring and the delicious yellow pears are ripe in October.

Kieffer Pear Tree Care

Kieffer Pear Trees are fast growing and can often set fruit in their first year in the ground. They are cold hardy down to 20 degrees F. Plant your new Kieffer Pear Tree in a spot that receives at least 6 hours of direct sunlight per day in the spring and summer months. Dig a hole that is twice as wide and as deep as the potted tree’s container. Fill with rich soil and water well.

Water Kieffer Pear Trees when soil is dry to 2 or 3 inches deep. In most climates this means watering your Kieffer Pear Tree about once per week. It is important that the tree is never saturated to a point where the soil remains soggy. In hotter months Kieffer Pear Trees may need more frequent watering. However, stop watering your Kieffer Pear Trees after the first frost of fall occurs. Resume watering when all threat of frost has passed in spring.

Fruit & Harvesting

The shape of a Kieffer Pear is that of a classic pear with the stem top being narrow, and the bottom widening to a rounded bell. Kieffer Pear Trees bloom sweet-smelling, white flowers in spring and are pollinated by honeybees, moths, bats, and butterflies. The pears start to ripen in September and can be harvested throughout the fall. Ripe Kieffer Pears are yellow with red blush, have crisp juicy flesh, and taste sweet but mild.

To harvest Kieffer Pears grasp the ripe fruit and pull with a twist. You can also harvest Kieffer Pears with hand-held trimmers. Harvested Kieffer Pears will keep fresh for a month or more in a cool dry place. You can also refrigerate them for longer, or peel and freeze them for cooking later. Fresh pears are great for salads, desserts, or for making smoothies and other beverages. The ripe fruit can be canned, made into pie filling, or baked into savory tarts.


Kieffer Pear Trees are able to grow fruit as soon as one year in the ground. Since the trees can produce fruit so soon, pruning young trees can help them grow a balanced shape to support the fruit. Prune the central leading branch in the tree’s first winter. Doing so will stimulate the growth of side branches and help the tree create a sturdy shape. Prune your Kieffer Pear Trees once per year in winter when the trees are dormant.

Kieffer Pear Trees perform best when the ground beneath them is free from deep grass, weeds, or other undergrowth. Pull weeds by hand and mulch under the tree with shredded tree bark, raked leaves, grass clippings, or wood chips. Pull stacked mulch back from the tree base, and always remove any trimmed branches or fallen fruit from the immediate area to discourage mold, fungus, and pests.
