Before applying a weed killer you should first mow your lawn and cut the top of the thistle weeds. A perfect mowing is recommended to see the progress early. Mowing includes cutting the top of the weed, uncovering the stem, and depleting its capacity to grow. After mowing, a first-working weed killer works like a charm. Applying weed killer during the active growth of weeds is recommended.

Thistle, an active-growing intensive weed often becomes intolerable. Some weed killers are effective to deal with thistles including-

Glyphosate, such as:

  • Clean the area and the tools youre using thoroughly before and afterward to avoid cross-contamination.
  • Dont use weed killers on windy days or near water. This can spread the product around, and it can get into waterways which can kill aquatic life.
  • Always use protective equipment such as gloves, masks, and clothing that covers your arms and legs.
  • Keep children and pets away from the area. If the product isnt pet-safe, keep the pets away until the packaging suggests.
  • Reserve products used for measuring and mixing the herbicides for outside use only. Do not bring them back into the kitchen.
  • Dont dump the excess mixture into the sink or a trash can. Save it for later and use it only on your plants.
  • Aim to kill weeds on a warm day. This will ensure better and faster results.
  • Lightly dampen the weeds before applying weed killers, but not after. You should aim to keep the area dry for two days, if possible, after application.
