The squirrels regularly attack the other bulbs in my garden but I don't find they touch the nerines. So I suspect you will be ok.

I have mine in a pot sheltered in a SW angle of the house wall so no probs with squirrels there. If they do bother you that may be a solution

Thank you so much -both of you That's a relief - I find hat the bulbs are quite expensive to keep buying when they disappear -so have put these near front door and labelled so that I don't lose them .....Ha Ha
