Pollen comes from plants, weeds, and trees growing everywhere. Allergy sufferers may be allergic to one type or all types of pollen. That being said, if you suffer from tree allergies, it may make your summer uncomfortable.

You cannot control every tree planted in your neighborhood, but you can control your own yard. Moreover, from this article, you will know what trees are safe for you to be near during peak pollen times.

We consider trees hypoallergenic if they are free of allergy-causing pollen. Even trees with heavy pollen that will not drift in the wind are better for allergy sufferers.

On a tree, the male flowers produce pollen. Therefore, trees that support both male and female flowers and completely male trees will produce pollen. However, a completely female tree will not produce pollen.

Planting all female trees in your yard will reduce the pollen around your home dramatically. However, it is not supportive of our pollinator friends like bees.

Altogether, all-female trees may not be the most decorative trees for your yard, but they may reduce your allergy symptoms greatly. The growing season is tough on so many of us, and controlling your environment is your right. Even by controlling your home, you may have a better spring and summer.
