Where are you posting from? Your frequent use of 'yard' suggests it
might not be the UK, in which case our advice will not be of much use to
you.

You may take that view of your own advice if you wish Kay, but many non
UK gardeners have been very grateful for help given to them by urglers,
and long may they continue to do so. Gardening is a global activity and
the Internet is a global means of communication. Any mailing about UK
recreational gardening is welcome here.
