5 Reasons Why Bradford Pear Trees Smell Bad
Bradford pear trees are commonly planted in residential and commercial landscapes for their attractive blooms and low maintenance requirements.
However, many people are turned off by the strong, unpleasant odor emitted by the trees, described as fishy, musty, or even resembling the scent of $emen. Here are five reasons why Bradford pear trees smell bad:
Chemical Compounds in Flowers
The main culprit behind the Bradford pear tree’s intense pungent smell is the chemical compound found in their flowers. It would be best if you tried to give proper care and maintenance to your tree to keep the smell less intense and unpleasant.
When the tree flower starts to wilt and decompose, they release compounds known as trimethylamine, which are responsible for emitting an unpleasant odor.
A study published in this Journal found that the Bradford pear tree flower contains a high level of trimethylamine, usually found in decaying fish and other organic matter.
This is why you should always pay attention to the maintenance of your yard and areas where this Bradford pear tree is grown. You must regularly clean the debris leaves and other parts of the tree, especially in the spring season.
Overuse in Landscapes
Another reason Bradford pear trees may smell bad is their overuse in landscapes. Many cities and developers have planted these trees extensively due to their fast growth & attractive blooms.
This undoubtedly contributes to large concentrations of Bradford pear trees in some areas, which can result in a stronger and more pervasive odor, especially during peak bloom periods.
Hybridization with Other Trees
I hope you know that Bradford pear trees are a hybrid of two pear species. They have been crossed with other pear varieties to create new cultivars with different characteristics.
Many of these hybrid trees may have inherited the unpleasant odor from one or both of their parent trees during the process. You should always thoroughly examine the plant before purchasing one from any nursery.
Few of these hybrids may not be as disease-resistant as the original Bradford pear, making it more susceptible to fungal infections that can contribute to a bad smell.
Environmental Factors
Environmental factors such as temperature, humidity, and air pollution can also affect the odor emitted by Bradford pear trees. You might know that Higher temperatures & humidity levels can cause the flowers to decompose more quickly, releasing more trimethylamine into the air.
Additionally, areas with high air pollution can exacerbate this odor by interacting with the chemicals emitted by the trees. Lastly, the soil quality & its type can also affect the odor of a Bradford pear tree.
As per my hours & hours of research, trees grown in alkaline soils with high nutrient levels & water availability are likely to emit stronger odors than those growing in acidic soils with lower nutrient levels & water availability.
