Elm

Elm trees are a type of deciduous tree that are native to North America, Europe, and Asia. They are known for their strong wood, which is why it was used in shipbuilding and for making furniture. Elm trees can grow to be over 100 feet tall and have a lifespan of around 200 years.

There are many different types of elm trees, but they all share some common features. Their leaves are simple and alternate, and they have a distinctive v-shaped notch at the base of the leaf. Elm trees are also known for their winged seeds, which are produced in pairs and are dispersed by the wind.

Elm trees are tolerant of a wide range of soils and climates, but they prefer moist, well-drained soils. They are also tolerant of urban conditions and can be found growing in cities all over the world.

Unfortunately, elm trees are susceptible to a number of diseases, including Dutch elm disease and elm yellows. These diseases can kill an elm tree within a few years. Dutch elm disease is caused by a fungus that is spread by a type of beetle. Elm yellows are caused by a phytoplasma, which is a type of bacteria.

Pollen from elm trees is a common allergen for many people

Pollen from elm trees is a common allergen for many people. The pollen is released into the air during the tree's flowering season, which typically lasts from late winter to early spring. If you're allergic to elm tree pollen, you may experience symptoms such as sneezing, runny nose, and watery eyes.

There are several species of elm trees, but the most common ones in North America are the American elm (Ulmus americana) and the European elm (Ulmus glabra). Elm trees are characterized by their large, oval-shaped leaves. They can grow to be quite tall, reaching heights of up to 100 feet.

If you're allergic to elm tree pollen, the best way to avoid your symptoms is to stay indoors when the pollen count is high. You can also try wearing a dust mask or using an air purifier to filter out the pollen. If your symptoms are severe, you may need to see an allergist for treatment.
