Thanks for all your comments
. Have to say I'm surprised that generally that there is a consensus of agreement for the landlord on this case. The garden was part of the national garden scheme of which the landlord knew about and actively promoted, even tarted up the property for the tv cameras. It just seems crazy to me that a wild life haven that was created at no cost to the landowners was either ripped up or gravelled over at the cost of the previous tenants. The property hasn't been advertised as vacant or available for let yet.
I would have to correct you BB that this estate is not a public effort......far from from it. They are a private rural estate/landowners who have been renting out for 100s of years. I have no idea who "our lovely granny is" so wasn't trying to make any comparisons.
My final point would be that this landlord passes on the cost of maintenance and insurance on to their tenants.It's them that pays.
I do appreciate your comments, thank you
