Hi, first time I'v 'posted', and i need your help! Moved into our new house three weeks ago, has a large established garden, and we dont know anything about gardening, so i will be picking your brains quite often. But the thing i am worried about at the moment is, we have a pear tree and all of its leaves are coverd with rust spots. does this mean that the tree has to come down? should i call a tree surgen? can they be trusted to give me the correct advice? The pear tree is close to other trees, hedges & rose bushes which are not affected. Any advice? Thanks
