Aha, the easy way to disencumber yourself from fallen leaves is to order the gardener to mow the rolling pastures of the estate. This is what happened to me yesterday
, but owing to the gale which blew all night long I now have short grass and a fresh crop of identical leaves
Your rowan problem is the opposite of mine - which spookily I was going to raise on another topic - my pyrawotsits have been surgically stripped in a fashion never seen previously (blackies and speugs) but the over-burdened rowan remains untouched and intact.
In normal years, apart from holly berries, the rowan is the beeline favourite, but not this year.
