What is the mixing ratio for Ortho Ground Clear?

The mixing ratio for Ortho Ground Clear varies depending on the specific product version (e.g., Weedkiller path & patio vs. heavy duty). Always check the back of the bottle for the exact dosage, but a common ratio is around 20ml to 50ml of concentrate per litre of water, or as directed by the cap measure for your sprayer's capacity.

How much Ortho Ground Clear do I need for my garden?

To determine how much you need, calculate the total area you want to treat in square metres. Multiply this by the water coverage rate (usually around 0.5 litres of mixed solution per square metre) to find your total water volume. Then, multiply the total water volume by the concentrate dosage rate stated on the bottle.

Can I mix Ortho Ground Clear in any garden sprayer?

Yes, you can use any standard pressurised garden sprayer. However, it is highly recommended to use a sprayer dedicated solely to weedkillers to avoid accidentally damaging desirable plants with residual chemicals. Make sure to rinse the sprayer thoroughly after use.

How long does it take for Ortho Ground Clear to work?

Ortho Ground Clear is a systemic and contact weedkiller. You should typically see visible results (yellowing and browning of leaves) within 2 to 4 hours on a sunny day. Complete kill of the weed down to the root usually takes 1 to 3 weeks depending on the weed type and weather conditions.

Is Ortho Ground Clear safe for pets and children?

You should keep children and pets off the treated area while you are spraying and until the solution has completely dried. Once dry, it is generally safe for them to walk on, but it is always best to follow the specific safety instructions and warning symbols on the product packaging.
