FAQs
Are these granules safe for pets and wildlife?
Yes, they are made from natural seaweed and are non-toxic, making them safe for use in gardens visited by pets or wild animals.
Can I use this on edible crops?
Absolutely. Because it is a natural product, it is perfectly safe to use around vegetables, herbs, and fruits.
How often should I reapply?
We recommend reapplying every 3-4 weeks, or sooner if the barrier becomes thin, disturbed, or washed away by heavy rain.
Does this product work on all types of slugs?
Yes, the spiky physical barrier is effective against common garden slugs and snails that crawl across the surface.
Do I need to mix these into the soil?
No, you should apply them on the surface as a barrier, but they will naturally incorporate into the soil over time as they break down, providing nutrients.
Troubleshooting
Slugs are still reaching the plants
Check that the application band is at least 50mm wide and that there are no gaps in the perimeter where slugs could crawl through.
Granules are washing away during rain
Apply a slightly thicker base layer and ensure the soil is lightly damp when spreading so the granules settle firmly.

Setup, Compatibility & Care
Preparation: Ensure the area surrounding your plants is relatively clear of weeds and debris before applying the seaweed layer to ensure a continuous barrier.
Compatibility: These granules are compatible with all soil types and most plant varieties, including edibles and ornamentals. They are safe to use in containers, raised beds, and traditional garden borders.
Maintenance: Check the barrier every 3-4 weeks. If you notice gaps or if the granules have been integrated into the soil by earthworms or foot traffic, apply a top-up layer. There is no specific expiration date, but store the remaining contents of the 7.5kg bag in a cool, dry place to prevent premature decomposition.
