FAQs

Is this safe for pets and wildlife?

Yes, as the product is 100% natural, it is safe for pets, birds, and other garden wildlife.

Can I use this on edible crops?

Absolutely. It is an excellent choice for vegetable gardens as it contains no synthetic chemicals or toxins.

How often should I reapply the granules?

For best results, reapply every 3-4 weeks or sooner if heavy rainfall has disturbed the barrier.

Does it work in heavy rain?

While the product is effective, heavy rain can soften the granules and wash them away; monitor the barrier after storms and replace as needed.

Will this alter the soil pH?

While seaweed can have minor effects on soil chemistry, when used as a surface barrier, it primarily serves as an organic amendment that adds beneficial nutrients as it breaks down.

Troubleshooting

Slugs are still crossing the barrier

Ensure the barrier is at least 50mm wide and that there are no gaps or debris bridges that slugs can use to climb over.

Granules are disappearing quickly

If the granules are washing away due to rain, consider reapplying a fresh layer once the soil has slightly dried to maintain the barrier's texture.

Pros and Cons

Pros

  • Completely natural and chemical-free
  • Adds nutrients to the soil as it decomposes
  • Safe for use around food crops and ornamental plants
  • Easy to apply as a dry granular barrier
  • Sustainable and eco-friendly harvesting process

Cons

  • Requires reapplication every 3-4 weeks
  • Effectiveness may diminish after heavy or persistent rainfall
  • Needs a specific application width to be truly effective

Setup, Compatibility & Care

To achieve the best results, clear the area around your plants of weeds and debris before application to ensure the granules sit directly on the soil surface. Sprinkle a layer approximately 2-3mm deep in a 50mm wide ring around the stems. Once placed, water the area well; this helps settle the granules into the soil profile and stabilizes the barrier.

When working in containers or pots, ensure the barrier reaches the edge of the pot rim to prevent slugs from climbing the sides. Store the remaining granules in a cool, dry location away from direct sunlight to maintain their integrity. Since the product is organic, no special handling precautions are necessary, but it is standard practice to wash your hands after gardening activities.
