Allergy-Free Gardening: The Best and Worst Trees for Allergies

Best and Worst Trees for Allergies

Loving the outdoors and having allergies is a cruel mixture, especially when you have problems sitting out in your own backyard. Now that the days are warm, and the sun is out, who can resist? But when your allergy symptoms start, it can quickly put a damper on your day. However, there are ways to help prevent this by incorporating particular plants in your yard to help reduce your exposure to pollen. While it is not easy to create a backyard that is allergen-free, there are avenues you can take to help minimize your exposure, and to do so, knowing the best and worst trees for allergies is essential.

If you want to have an “allergy-free garden,” half of the battle is selecting hypoallergenic trees. Keep asthmatics and allergy sufferers in mind with this helpful list of the best and worst trees for allergies.


When you are looking to incorporate trees into your outdoor garden, you should avoid using monoecious trees. Monoecious trees have both female and male parts, and because of this, they produce pollen. If you have asthma or allergies, avoiding these species are best since they all produce pollen that can trigger a reaction.

The examples of monoecious trees include:

• Oak trees
• Cottonwood trees
• Spruce trees
• Birch trees
• Pine trees
• Aspen trees
• Elm trees
• Hickory trees
• Beech trees


Dioecious trees are either all male or all female, never both. The male tree produces plenty of pollen, where the female tree does not. When choosing dioecious trees, make sure you select a female tree (not a male) to help reduce your pollen exposure. Just note that female dioecious trees are seed and fruit bearers, so additional yard maintenance and cleanup may be needed.

The examples of dioecious trees include:

• Female red cedar trees (AKA juniper trees)
• Female mulberry trees
• Female red maple trees
• Female ash trees
• Female silver maple trees
• Female poplar trees
• Female willow trees
• Female ginkgo trees
• Female holly trees
• Female fir trees
