tree people use a leaf blower, dont get an electric one, waste of time, some even suck up the leaves..check this link for more info.. http://www.abbeygardensales.co.uk/su...s-0000124.aspx

As for the advice to ingore a tree preservation order, don't do it, the person cutting down the tree can be liable for a fine of thousands of pounds, walnut trees are rare and lovely...keep it and adapt to it..give it the respect it deserves....
