How to Spot Spray Thistle With Glyphosate

Overview

When ugly thistles grow among your desired plantings, remove them to restore your beautiful landscaping. Glyphosate is a powerful chemical contained in non-selective herbicides. Select an herbicide containing glyphosate as the active ingredient and use this herbicide to remove thistles. Spot spray the glyphosate at the beginning and end of the growing season for effective thistle eradication, taking care not to apply the glyphosate to any desired plants in the process.

Step 1

Cut a 4- to 5-inch diameter hole in the center of the tarp with the scissors. Fit the hole in the tarp down around the thistle.

Step 2

Wear the plastic gloves and the eye protection whenever you handle glyphosate to protect yourself from this chemical. Wear long sleeves and long pants. Choose a sunny and windless day with temperatures above 60 degrees F.

Step 3

Spot spray the glyphosate spray carefully onto the thistle to saturate the foliage thoroughly. The tarp will protect surrounding grass and plants from over spray.

Step 4

Wait two to three days and then assess the condition of the thistle. Reapply the glyphosate if the thistles do not seem to be visibly dying.

Step 5

Reapply the glyphosate again at the end of the growing season if any new thistles appear over the summer. Use the same technique.

Step 6

Dig up the remaining foliage and root systems of the dead thistles with the weeding fork after the glyphosate kills them.

Tips and Warnings

  • Keep children and pets away from the treated thistles until the glyphosate dries completely.
