10 Trees You Should Never Grow in Your Yard 

If you put the right kind of tree in the right place, it can make your yard look better and gain value. You DON'T want to plant these 10 trees around your house. 

The Callery Pear (Pyrus calleryana) has spring white blossoms and fall red foliage. Naturally weak, the expanding structure breaks in wind, snow, and ice. Many states consider the callery pear and its most prevalent variant, Bradford, invasive trees.

In all kinds of harsh environments, Siberian elm (Ulmus pumila) grows quickly and aggressively. It's dirty, seeds everywhere, and isn't the prettiest tree. Weak-wooded Siberian elm is susceptible to storm and ice damage.  

2. Siberian Elm

The imported pest Tree of Heaven (Ailanthus altissima) is filthy, invasive, and unsuitable for household landscapes. It seeds everywhere and releases a toxin that kills competing flora, making landscaping difficult. 

3. Tree of Heaven

Lombardy poplar (Populus nigra) was a popular fast-growing screen tree. It was the ideal tree, growing four to five feet a year in an upright shape for many backyards.  

4. Lombardy Poplar

Silver maple (Acer saccharinum) is the ugly duckling of maples. Some put on some fall color, but sugar, black, and Japanese maples do better. Silver maple grows quickly and has numerous trunks. 

5. Silver Maple

Weeping willow (Salix babylonica) by the coast is pretty but too big and disorderly for most dwellings. This one should stay near water and away from your yard because its roots explore everywhere for water, especially near septic systems and sewer pipes 

6. Weeping Willow

Many people have allergic reactions to staghorn sumac (Rhus typhina), a poison ivy relative. It looks beautiful in fall, but its roots keep sprouting, so you soon have a colony of staghorn sumacs giving your skin the willies. 

7. Staghorn Sumac

Mulberry (Morus spp.) is a filthy tree that shouldn't be near your road, sidewalk, porch, deck, patio, pool, or yard. Fruit stains everything. Though bland, the fruit is edible. Birds eat most of it and deposit droppings on your car.  

8. Mulberry

Yards benefit from male Ginkgo (Ginkgo biloba) trees. It has pretty buildings, fall foliage, and a dinosaur-era ancestry and grows slowly to moderately. Female ginkgos produce vomit-smelling fall fruit, so avoid planting them. 

9. Ginkgo

Ash trees (Fraxinus spp.) have many benefits. Strong, fast-growing plant with stunning fall color. Unless you're willing to pay to inoculate your tree every two years, the emerald ash borer is decimating ash tree populations, so choose a less endangered variety.  

10. Ash
