A tempory remedy I was tot by a pest control person. Spread moth balls or crystalls around base of plant. The squirrels cannot stand the odors. However when it rains or you water the moth balls dissolves. Plus be careful not to have kids around or toddlers,
They also get attracted to moth balls thinking it maybe candy.
So, Becareful follow direction for kid proff. Then if thats not a problem keep in mind other pets can get sick also from Moth
balls. So, Good Luck:
