Snails and slugs ... a gardeners enemy!
They attack many kinds of plants, especially young plants and the soft, succulent growth of herbaceous perennials and vegetables. Slugs provide a useful function by eating dead plant tissue and they are more prevalent on soils with high organic matter where manure and compost have been applied. They are more active in wet years.
Don't the thoughts of them slimming their way over your plants make your skin crawl! Personally, I wouldn't mind if they had an odd nibble, but they never seem content unless causing havoc and inviting all their relations and friends over for a good feed until they have damaged the plant.
I think the term snails pace does not do justice to the speed at which they can demolish a young plant after a lovely rain shower!
There are many ways of dealing with them ... here is a link to how to deal with them organically. With some of the ingredients of slug pellets being banned shortly, we must look to new methods and or course for our environment.
New Method - using recycled glass
I tried a new method on a few plants this year. I was lucky enough to be given a bag of crushed glass ( the type they use mixed with sand for sand blasting) from my friend Donal. See below for some before and after pictures of how successful it was. It would have been more successful if my cat didn't like digging in the bark around the beds! This trial was done over approx 4 weeks.
Crushed glass:

The glass is very fine - there are different sizes you can order. I didn't need any special protection and didn't get cut handling it without gloves. See below for contact details if interested in trying it.
The before and after photos:
Lemon Thyme ( 2 plants)
Before:
Note - more glass was applied after this photo, but I didn't take a more up to date photo
After:
As you can see there is a huge difference in the improvement. It would have been even better, but I didn't notice for the first week that there was a slug hiding within the barrier. Lesson learnt for future to check the inner circle for these pests!
Lupin:
For some reason the slugs/snails were only attacking one of the plants - think they were keeping the other plant for the following week. Here you can see how deep the glass was applied - and this was the depth for the others, I just forgot to take the photos again!
Before:

| Including the lupin that was untouched. |

| A close up of the slug/snail damage. |
After:
 |
| Much more healthy leaves |
 |
| Even a beautiful Lupin flower! |
Summer bedding
Before:
After:
 |
| After 4 weeks - most of the glass still intact in this bed |
Even some beautiful flowers off plants I had given up for dead which they would have been without the glass protecting them. Here you can see the cat wasn't as active at this bed!
Result:
The trial was a huge success as you can see from the above pictures. I found in cat busy areas, I would need to reapply about every 2 weeks, but in the less cat traveled areas, I would only need to apply or touch up every 4 weeks. I believe that if I wasn't using bark for ground cover, this could even be elongated - perhaps even yearly!!!
The product is pet friendly as it didn't bother my cat around those areas!
