Choosing the right trees for your yard is a big decision, and especially if you or your family members suffer from seasonal allergies, you need to know what are the worst trees to plant if you have allergies … so that you can avoid them and choose safer alternatives.

Many trees produce large amounts of pollen, which can cause sneezing, itchy eyes, and other uncomfortable symptoms. For homeowners in Fresno and surrounding areas, where pollen season can last longer due to the mild climate, selecting low-allergy trees is especially important.

Here are some of the worst trees to plant if you have allergies, and some tips for choosing allergy-friendly options instead.

8 of the Worst Trees to Plant if You Have Allergies

Of course, every individual has specific things that trigger an allergic reaction. In general, though, pollen is a common culprit. The amount of pollen produced by the trees on this list place them among the trees to avoid planting if you or your family members have allergies.

1. Oak Trees

Oak trees are a common source of airborne pollen that can trigger significant allergy symptoms. These trees release pollen over an extended period in the spring, making it difficult for allergy sufferers to get a break.

Valley Oak is a common variety in Fresno, and while they’re great shade trees, they’re not the best choice for allergy-prone yards.

2. Ash Trees

Ash trees produce pollen that is highly allergenic, causing common hay fever symptoms. These trees are often chosen for their sturdy growth and shade potential, but they can lead to increased pollen levels around the home.

Modesto Ash is a popular choice in Central California landscapes, but they can release significant amounts of pollen.

3. Juniper and Cedar Trees

Junipers and cedars release fine pollen that can spread easily and trigger allergic reactions, particularly during the late winter and early spring. These trees are known for creating clouds of pollen that travel long distances.

Many Fresno-area homes and landscapes feature California Juniper and Eastern Red Cedar, which, while drought-tolerant, can be problematic for those with allergies.

4. Mulberry Trees

Mulberry trees are prolific pollen producers and can aggravate allergies, especially during peak pollen seasons in the spring. Their pollen can be particularly irritating to the respiratory system.

The Fruitless Mulberry a popular tree choice in the Central Valley due to its shade. However, it is notorious for causing allergy issues and has even been restricted in some regions.

5. Pine Trees

Pine trees release significant amounts of pollen, though their large pollen grains are not as easily airborne as others. For those with sensitivities, even slight exposure to pine pollen can be a trigger.

Monterey Pine and Ponderosa Pine are common in Central Valley landscapes but can cause issues for allergy-prone homeowners.

6. Olive Trees

Olive trees are notorious for producing large amounts of pollen, which can significantly impact those with respiratory allergies. The allergenic potential of olive pollen is so high that some cities regulate olive tree planting to reduce pollen levels.

European Olive is a popular variety, but it’s often avoided in newer landscaping due to their allergenic impact.

7. Sycamore Trees

Sycamore trees release fine, hair-like seeds and pollen that can irritate the respiratory system. Additionally, the small fibers on sycamore bark shed in spring, aggravating allergies further.

California Sycamore is a variety commonly planted in Fresno for shade and landscaping, but these trees can cause substantial allergy issues in the area.

8. Elm Trees

Elm trees, especially during the spring, can release heavy amounts of pollen into the air. Their long pollination period contributes to prolonged allergy symptoms.

Chinese Elm is commonly found in Central Valley landscapes, offering ample shade but not without pollen drawbacks.

Tips for Choosing Allergy-Friendly Trees

For allergy-prone households, you should avoid the trees listed above and choose trees that are low-pollen or pollen-free instead. Here are a few allergy-friendly trees to consider for your Fresno landscape:

  • Female Ginkgo Trees – Ginkgos do not produce significant pollen and are a great low-allergy choice.
  • Crepe Myrtle – This beautiful flowering tree produces little pollen and adds vibrant color to the yard.
  • Redbud – Known for its stunning spring blooms, Redbuds are relatively low in pollen and can add visual interest.
  • Magnolia – These trees produce large, showy flowers and minimal pollen, making them ideal for allergy sufferers.
