Wild Onion is a
"cool season" perennial weed common in the Southeast.
Although it is a close relative to the types cultivated in your
garden, Wild Onion is very undesirable when it starts appearing in
your turf. Wild Onion has slender, hollow, tubular leaves and will
produce small, greenish- white flowers. You will recognize Wild
Onion by the distinctive Onion aroma when you crush a bulb. Wild
Onion reproduces by seeds, aerial bulbils, and through their
underground, tuberous root system.
This perennial
will appear in the early Spring and late Fall and it is hard to
completely eradicate, unless you dig it all out. For small problems,
this is the best solution. You must take care to remove all the
roots and bulbs.
For
larger infestations, there are herbicides available. However,
because the Wild Onion has a tough outer-casing on its leaves,
herbicides have a difficult time sticking to them. Herbicides will
damage, control, and reduce Wild Onion, but will not eradicate. Wild
Onion should be dug out whenever possible, and if caught at first
appearance, will not become a major problem.
