trees can spruce up your home landscape, but choosing
the wrong tree can cause some major headaches. Here are
five species you might want to avoid when planting
Black walnut tree
walnuts are often grown for their shade and edible nuts,
but their buds, roots and nut hulls release significant
levels of juglone, a chemical that robs sensitive plants
of needed energy.
vegetables planted in close proximity to black walnut
trees are highly prone to wilting and eventual death.
Vulnerable vegetables include tomatoes, peppers,
asparagus, cabbage, eggplant, potatoes and rhubarb.
affected by black walnuts include apple, pear,
crabapple, and pine. Lilies, petunias and some
chrysanthemums are also vulnerable, as are blackberry
and raspberry bushes. Planting a tree is an easy job,
but it takes more skill than you might think. The
following tree-planting tips can help ensure you plant a
tree that thrives.
Bradford pear tree
Bradford pear tree is sensitive to leaf scorch and fire
blight, but branch splitting remains the biggest
problem. Bradford pears are top heavy and have a
v-shaped crotch, which makes them prone to splitting. It’s
not uncommon for the Bradford pear tree to split in
half, especially during sever weather.
ash tree is a target of the emerald ash borer (EAB), a
beetle once native to East Asia. Initially found in
Michigan in 2002, EABs likely arrived via packing
materials made of ash wood.
threaten the more than 8 billion ash trees in the United
States, where they’ve often been planted in
residential settings due to their resistance to severe
weather, diseases and pests. While nibbling by mature
EABs can hurt foliage, the worst damage comes from their
larvae, which feed on inner bark, thus disrupting water
and nutrient transport.
bark, heavy woodpecker activity, leaf loss and water
sprouts at the trunk are all signs of EAB
on five continents, slow-growing gingko (biloba) trees
can reach 115 feet and are popular residential trees
because of their durability.
problem comes in late fall, when female trees produce a
putrid-smelling "fruit," which sticks to shoes
and can get tracked indoors. Because there’s no
way to distinguish male and female varieties at the
seedling stage, the ginkgo tree is plagued by the
you really want a stink-free ginkgo tree, seek out
Autumn Gold and Lakeview varieties, which are male-only.
it can be beautiful, especially in the fall, the
sweetgum’s spiny brown balls, which come down by the
thousand, are a major drawback.
are many ways the "gumballs" might cause
injury. You can slip and land on them as they roll. Shot
out of a lawnmower, they become a hazardous projectile.
They also don’t rake easily, so you have to pick them
up by hand, an unenviable task.
