We are renting a flat with a nice garden in Leeds UK. It has a nice garden in the back yard and when we moved in in July 2014 there were 4 healthy ferns pleasing my eye.
Now, with winter having passed, they all seem to be dead and I do not know when exactly that happen.
I tried to search google for clues about why this might happen, but could not find anything.
Could anyone tell me if this is a normal thing or not (are ferns supposed to not survive English winter?). Could it be a disease?
I have no idea as to what kind of ferns they are, but maybe this picture would clarify this:
