Nutshells as pest defence?

Hi All,

We have plenty nutshells going spare at this time of year with a bowl of nuts and the nutcracker permanently to hand. I wouldn't consider putting them in the compost as I'm sure they would take far too long to break down, so we normally throw them onto the fire while its burning (as it is every evening). I wondered if anyone uses them as slug defence around plants or border edges, much like crushed eggshell? Or has anyone any other clever uses that they wish to share?

Crushed nutshells are good for topping off potting compost on indoor arrangements  / plants rather than just seeing bare compost. Also mix them with the compost if you need more drainage. Must admit, I usually just throw them on the fire as well.  :happy:

I had visions of walnut shells in a catapult as a defence against rats .....   

Bit disappointed now ..   

Nah! That would be a Ratapult

And I was just thinking of an old blunderpuss full of shells blasting a few slugs     

I don't think anything can top this for ingenuity.

Thanks Ice, I'll have to show no.6 son this 

The more we know, the more we know we don't know.  :blink:

That's the wonderful thing about life, everyday you can learn something new and still be clueless 

 

Thanks all, for your useful and erm.... unusual ideas for uses of nutshells!
