"stop watching that plant?' Could someone explain what that means please, I had a notification saying just that.
I believe it's the same as "stop watching a post". If you click on that option, you won't receive email notifications when it's been updated or commented on.
Chocolate, since you have been adding photos, etc to some of the plant pages you are receiving notifications anytime someone else adds to that plant page. So like Cheryl said if you don't need to keep track of a particular plant, just click on Stop Watching This Plant and you won't receive them any more.
