Bad Fruit: Removing Bradford Pears from the Garden

The Flowers of Evil has been described as beautifully morbid, juxtaposed against the rotting sewage of the masses. The flowers of Callery pears, though not visibly malefic, are an entire heaping of bad news. 

The Bradford pear’s growth pattern can best be likened to that of a feral cat who likes to piss on others’ territory. Also known as Callery pear, this unsavory specimen can be deceiving, its branches glaringly conspicuous when covered in blizzards of white blossoms. However, its cloying scent, akin to a dead fish, its tendency to sprout piercing thorns that can shred tires, and its invasive nature—all makes it highly undesirable. With a reputation as one of the most hated plants in the nation, this is one tree to avoid at all costs, or as the saying goes, off with its stump. 

 

A History of Good Intentions Gone Wrong

The Callery pear (Pyrus calleryana) wasn't always the villain of the American landscape. Introduced from China in the early 20th century, it was initially hailed as a miracle of horticulture. It was resistant to fire blight, grew rapidly in almost any soil, and offered a perfectly symmetrical lollipop shape that made them desirable to suburban developers.

For decades, Callery pears were thought to be sterile, until they started cross-pollinating with cultivars that had been planted in proximity to one another. The most famous of these, the 'Bradford', was marketed as the ultimate urban tree. However, as nurseries developed newer cultivars like 'Aristocrat' and 'Cleveland Select' to fix its notorious structural weakness, the sterile promise evaporated.

Cross-pollinated by bees, with fruits eaten by birds, the seeds were readily dispersed far and wide. By the 2000s, Callery pear trees have inundated urban landscapes with their foul stink, aggressively invading prairies and other natural areas.

The Environmental Toll

As seen above, good intentions don’t always translate to winning solutions. Bradford pears are deeply problematic because their aggressive spread and thorny thickets quickly crowd out native plants and alter ecosystems. Unlike the manicured versions in your neighbor’s yard, wild Bradford pears often revert to their ancestral form, sporting four-inch thorns capable of puncturing tractor tires and mangling lawnmowers.

They tend to form dense monocultures, crowding out native species and destroying local biodiversity. When these trees take over a meadow, they don’t just replace one plant; they collapse an entire food web. Worse than a dried granola bar left behind in the car, the leaves offer zero nutritional value to native caterpillars. What looks like a lush green forest to the untrained eye is, in reality, a biological desert.

Why the Tide is Turning

Across the United States, the legal landscape is shifting. Now that their harm has become apparent, a growing number of states and cities are banning these trees, and even paying people to get rid of them.

States like Ohio, Pennsylvania, and South Carolina have enacted bans on the sale and distribution of the tree. Many municipalities have even launched elimination programs, offering homeowners a free native replacement tree—a serviceberry or a flowering dogwood—in exchange for a photo of a cut-down Bradford pear in their yard.

How to Get Rid of a Callery Pear Tree

If you have one of these “evil flowers” in your yard, the best time to act is now. However, removing a Bradford pear is a burden—devilishly complex. These trees are survivalists, designed to sprout back with a vengeance if the job isn’t finished.

1. Timing the Execution

The first step is to cut them down, preferably in late winter or early spring before the tree starts to bloom. This prevents it from eventually producing seed-filled fruit that birds will carry into nearby woods. Cutting them before they leaf out also makes the cleanup process significantly less messy.

2. Stump Treatment

If you simply cut the tree and walk away, you will have a dozen revenant saplings growing from the stump by mid-summer. Dig up the stump and/or apply herbicide to keep it from re-sprouting. A systemic herbicide (like triclopyr or glyphosate) applied directly to the freshly cut outer ring of the stump (the cambium layer) is often the most effective way to kill the root system.

Experts recommend having this done by certified professionals, to avoid harming surrounding plants. A professional can ensure the herbicide is applied precisely, preventing runoff or environmental drift that could spoil your lawn.

3. Long-term Surveillance

After the tree is gone, it’s also important to monitor the area for new seedlings. Seeds can remain viable in the soil for several years, so keep a sharp eye out for those distinctive heart-shaped, shiny leaves emerging in the spring.

Better Alternatives for Your Landscape

Removing a tree leaves a literal hole in your landscape, but it’s an opportunity for a renovation. Instead of a brittle, smelly invasive, consider planting native species that offer better aesthetics and actual ecological value:

Serviceberry: Beautiful white spring blooms and edible berries that birds love.

Eastern Redbud: Stunning purple flowers and heart-shaped leaves without the smell.

Flowering Dogwood: A classic, elegant tree with high wildlife value.

Magnolia Tree: Provides a cloud of pink flowers, notable for their heavenly fragrance. 

The Bradford pear is a testament to the fact that not everything that glitters—or blossoms—is gold. While it may provide a fleeting moment of white beauty in April, the year-round cost to people’s noses and native ecosystems is simply too high. Hopefully, with dedication, gardeners and environmentalists can band together and make Callery pear a thing of the past.
