Garden Basics 1L Weed Kill Concentrate is the workhorse bottle for the parts of a garden where weeds keep winning. It is non-selective and non-residual, so it kills weeds down to the root, then breaks down in the soil rather than leaving the ground sterile.
Why you'll love it
-
It gets the roots, not just the top. It moves through the plant, so perennial weeds and running grasses do not reshoot.
-
Non-residual, so you can replant. Plant out a treated bed once the weeds have died and the label interval has passed.
-
Concentrate economics. One litre makes a lot of spray, far cheaper per square metre than ready to use bottles.
How to use it
Mixing. Dilute to the label rate table, which differs for annual weeds, established perennials and woody regrowth. Half fill the sprayer, add the concentrate, top up and agitate. Mix only what you will use that day.
Application and timing. Spray actively growing weeds on a still, mild morning, wetting foliage evenly to runoff. Drought stressed or freshly mown weeds take up very little. Avoid wind, hot sun and rain within the label rainfast period. Expect yellowing in about a week and full brown off in two to three.
Care around desirable plants. It damages anything green it touches, including lawn and the green bark of young trees. Use a shielded nozzle or cardboard along garden edges and keep pressure low so the spray does not drift.
What it suits
Driveways, paths, paved joints, gravel, fencelines and the perimeter of sheds, tanks and buildings. It is not a lawn weeder: for weeds through turf you want a selective product.
What to expect when it arrives
Supplied as a 1L bottle of concentrate. Store it upright and sealed, out of direct sun and away from children and pets. Always read the full label and follow the stated protective equipment, rates and withholding periods. Delivered Australia wide, with delivery from $29.95.
