Information on a Keifer Pear Tree's Growth


Rate of growth refers to vertical increase, according to the Arbor Day Foundation. Rate and size are influenced by numerous variables such as soil, water, drainage, fertility, light and weather.

Rates of Growth

There are three rates of growth: slow, medium and fast. These rates are determined by the number of inches that a tree grows within a year: slow is 12 inches or less; medium, 13 to 24 inches; and fast, 25 inches or more.

Kieffer Pear

The Kieffer pear is designated as a fast grower. This means that it will grow 25 inches or more within a year.

Mature Size

A mature Kieffer pear tree generally grows 15 to 30 feet in height. The spread of a mature tree will be 12 to 20 feet.

Growing Conditions

A Kieffer pear tree requires full sun and prefers soil that is minimally acidic, heavy and well drained.


The large, yellow fruit of the Kieffer pear is produced in late September to October. This pear tree is one of the few that self pollinate and is hardy in zones 4 through 9.
