How to Use

  1. Shake the bottle well before use.
  2. Ensure that weeds are dry and not wet from rain or watering.
  3. Adjust the nozzle to a fine spray setting for best results.
  4. Spray the targeted weeds thoroughly, ensuring all plant parts are covered. Be cautious around desirable plants, as spray drift can cause damage.
  5. Allow the spray to dry before pets return to the treated area.

Notes from Aqua Gardening

  • Do not apply to wet weeds or if rain is anticipated, as moisture will dilute the spray's effectiveness.

  • Keep pets off treated areas until the spray has dried.
  • Do not spray on porous surfaces without spot testing first, as Slasher Weedkiller may cause discolouration on porous hard surfaces like pavers and bricks.
