How to Eliminate Thistle: Persistence Is Key

Thistle's deep, extensive root system makes it tough to eradicate, especially if neighbors have it and seeds blow in yearly. The secret is persistence: every time you see regrowth, spray, dig, or cut and cover. Repeatedly starving the roots eventually exhausts them.

A 2-inch mulch layer (pine needles, shredded wood, pecan hulls) isn't a cure-all but significantly reduces seed germination and weakens existing roots. Maintain it consistently.
