AUBURN, May 10---Despite their standing as
one of the most popular landscape trees in the Southeast, Bradford
pears aren’t what they’re cracked up to be.
For
despite all the beauty they lend to thousands of landscapes
throughout the region, the trees are plagued with one fatal flaw:
due to their combination of vigorous growth, weak wood and poor
branch structure, they often begin falling apart after only 20
years.
Experts say homeowners and others would be far
better off buying other trees – trees that lend beauty to the
landscape and last longer.
Mary Beth Musgrove, an Alabama Cooperative Extension
System horticulturist, says homeowners can choose from a variety of
alternatives that lend both beauty and hardiness to the landscape.
"Chinese Elms are an excellent choice, although
consumers should be careful not to confuse these with Siberian Elms,
which are often passed off as a poor substitute for Chinese
Elms," Musgrove says.
To ensure you’re buying the right elm, Musgrove
says consumers should look for "small, reddish-brown, pointed
leaf buds and beautiful cinnamon patches of bark."
Siberian Elms, by contrast, have round, black leaf
buds.
In addition to being long-lived, Chinese Elms, are
resistant to Dutch elm disease and do not have the pest and dieback
problems associated with Siberian Elms.
Other fast-growing alternatives include the Chinese
Pistache and Japanese Zelkova.
Crab apples and Japanese cherries are also good
alternative flowering ornamental trees, although homeowners should
remember fruit can cause branch stress on some cultivars.
Red maples also are a good choice.
In the meantime, Musgrove offers advice for
homeowners who insist on sticking with Bradford pears.
First, mulch around the trees and fertilize no more
than you would the rest of the landscape.
If you insist on buying Bradford pear trees, you can
minimize the risk of your trees eventually collapsing by picking
trees with a strong single leader and eliminating branches that
intersect with the trunk at sharp angles.
Nevertheless, she believes homeowners would be much
better off choosing another tree.
Bradford pear trees first gained a toehold in the
American horticultural scene in the 1950s, when researchers with the
Agriculture Research Service in Glenn Dale, Maryland, noticed an
especially promising tree grown from seed collected in China more
than a half-century earlier.
"It took another couple of decades for the tree
to gain in popularity in the Southeast," Musgrove says,
"but by then plantings could be detected all over the place --
on home landscapes, along roads and in highway medians."
While many homeowner associations and local
municipalities have quit planting the trees after learning of their
weaknesses, Bradford pear trees remain a hot seller.
Last February, however, Bradford pears trees were
removed from the parking lot of the U.S. National Arboretum after
being displayed for decades – a telltale sign of the trees
declining popularity among horticultural experts.
