FAQ
What dilution ratio should I use for general weed control?+
For general weed control in a sunny area, we recommend diluting 25ml per 5 litres of water. Always test on a small area first to assess the product's effect and ensure it doesn’t harm desirable plants.
Can I use this concentrate on vegetables?+
Yes, you can, but with caution. Dilute at a lower rate – around 12.5ml per 5 litres of water – and test on a small area first to ensure it doesn’t affect your vegetable growth.
How often should I apply this product?+
The frequency of application depends on the severity of the infestation. For light weeds, apply every 7-10 days. For heavier infestations, you may need to apply more frequently – up to twice weekly initially – until the problem is under control.
Is this concentrate safe for use around pets?+
While formulated with relatively low toxicity, it’s always best to exercise caution. Keep pets away from treated areas until they are dry and ensure thorough rinsing of any exposed skin or fur.
What does this product do specifically against pests?+
This concentrate contains ingredients designed to disrupt the nervous systems of common garden pests like aphids, caterpillars, and slugs, leading to paralysis and eventual death. It's effective on a range of insects that damage plants.
How long will it take to see results?+
You should typically start seeing visible results within 24-48 hours after application, as the active ingredients begin to work. However, complete eradication may require multiple applications over several weeks.
Can I use this concentrate with other garden products?+
We recommend avoiding combining this concentrate with other pesticides or herbicides unless specifically advised by a qualified horticultural professional. Combining chemicals can increase the risk of harm to plants and the environment.
What surfaces is this safe to apply on?+
This concentrate is generally safe for use on soil, gravel paths, patios, and paved areas. However, avoid applying directly onto delicate plant foliage or near water sources where runoff could occur.
How should I store the unopened bottle?+
Store the unopened bottle in a cool, dry place away from direct sunlight and out of reach of children and pets. Avoid storing it in areas with extreme temperatures as this can affect the product's stability.
What if I accidentally spill some concentrate on my lawn?+
If you accidentally spill some concentrate, immediately flush the area thoroughly with water. Monitor the affected grass for any signs of discoloration or damage and contact us if you have concerns.
