Worst trees in Houston, Katy, San Antonio, Austin, and Dallas (for pollen allergies)

In Texas, several tree species are known for producing significant amounts of pollen. While the specific ranking may vary depending on the region and environmental conditions, some of the trees that tend to produce the most pollen in Texas include:

Cedar (Juniper) Trees: Ashe juniper (Juniperus ashei), commonly referred to as "cedar" in Texas, is notorious for producing large quantities of pollen, especially in central and western parts of the state. Cedar pollen is a well-known allergen, and its release typically peaks in the winter months. Houston government does not measure cedar due to its location, as Houston is east coastal, but if you live elsewhere you may experience issues with cedar.

Oak Trees: Oak trees, including species like the live oak (Quercus virginiana) and post oak (Quercus stellata), are prolific pollen producers in Texas. They are common throughout the state and can release substantial amounts of pollen, particularly during the spring and early summer months.

Mulberry Trees: Various mulberry species are found in the area and can produce pollen in the spring. Although not as notorious for pollen production as some other trees, they can still affect allergy sufferers.
