Thistle

In Lawns

• Apply a selective herbicide like LawnPro Turfclean Ultra or LawnPro Turfclean. This will effectively control thistles but will leave lawn grasses unaffected.
• Because of the large rosette habit of thistles in lawns they can be easily spot treated with Weed Weapon Invade Gel.
• In Tall Fescue and Turf Ryegrass lawns treat with LawnPro Ultra Poa Lawn Weed Control in spring or autumn.
  • Dilute 40mL of product in 2L of water and spray the area.
  • Re–apply 21 - 28 days later for optimum results.
  • Once the weeds have completely browned and died back (usually after about a week), it means the herbicide has done its job right down to the roots. At this stage, give the area a gentle rake or a light dethatch to clear away the dead foliage, this helps the soil breathe and gives your grass a better chance to bounce back. Try not to pull the weeds out by hand though, as this can stir up the soil and create the perfect spot for new weeds to pop up.
  • In the event of large gaps, rake the soil lightly and re–seed with LawnPro Smart Patch Mix or LawnPro Smart Lawn Seed.

NOTE: Do not use LawnPro Ultra Poa Lawn Weed Control on your tall fescue lawn if it is showing signs of stress or poor growth.

• For best results use in Spring and Autumn when weeds and turf are growing.

In Garden Beds

• Knock down weeds quickly with Weed Weapon Extra Strength, Weed Weapon Rapid Action or Weed Weapon Woody Weeds. It is biodegradable in the soil so planting can be carried out 7 days after treatment.
• For best results, use in spring and autumn when weeds and turf are growing.
• For a fast–acting organic solution on young thistles, use Weed Weapon Natural Power.

On Paths and Driveways

• Knock down weeds quickly with Weed Weapon Extra Strength or Weed Weapon Rapid Action. Then for long term control on paths and driveways, use Weed Weapon Long Term. This will kill a wide range of weeds and prevent re–growth for up to 12 months.
• For best results, use in spring and autumn when weeds and turf are growing.
• For a fast–acting organic solution on young thistles, use Weed Weapon Natural Power.
