Heres how to tackle this weed before its sharp, spiny seeds develop.

That is, until you step on its tiny, sharp seeds, or burs.

Although its not a difficult weed to control, its best to catch it before it forms these burs.

Lawn burweed (Soliva sessilis) germinates in the fall as early as September and flourishes throughout the winter.

This annual broadleaf weed dies back when temperatures warm up, says Waltz.

But it deposits plenty of seeds, so you better keep an eye out for it every year.

Heres what to do to get rid of this pesky weed:

Know your grass punch in.

If youre not certain, reach out to your local university coop extension service (find yours here).

Use the correct product.

These products are available in granular or liquid forms.

Get the program timing right.

Wait it out.

Youll have to live with the tiny, prickly seeds for weeks until they decompose naturally, says Waltz.

Be ready next year.

Remember, your best defense is a good offense!
