Cows in garden
I have a small garden that backs onto a farmers field. The cows eat all the ivy that is growing on the wall bull every few months they push the wall down and start eating everthing including Pyrocantha and burberis although they do leave the fox gloves alone. Can anyone suggest something I can plant that gives a bit of colour but that the cows might leave? They do love all the herbs, nettles.blackberry, brambles even honeysuckle. The garden is north facing and only get sun from may to end of sepember, I'm also in the peak district park over 1000ft. Help please? ps am considering moving but the views are beautiful.
