I found a really good idea! I have problems with my cats digging in my pots. Thanks to the Dollar Tree who had some cat videos for a $1 a piece I found that cats highly sensitive noses hate the smell of mothballs.
I found them in the loundery section of wall mart with the iron bord covers( wich was no easy find). It seems to work. Moth balls are poisonus though if eaten so I put some in a little organza bag and tied it to the pot.
Suposedly you can put them whearever you dont want your little ones to be. all i can say is My plant is finally growing agen.
