Hello I have several queries. Firstly, has anyone heard of sycamore trees being split in half by parasites? We have two trees in our garden that have been attacked by something and the trunk has halved in depth. I don't know whether they will survive or whether I should get them removed. Secondly, can anyone recommend decking installers in London or Surrey? Lastly, looking for someone to do light garden maintenance (weeding, treating lawn etc)and don't want to pay loads - any ideas? Thank you (in advance).
