We have a lovely big old tree - approx 12metres tall. Has been neglected for many a long year (previous owners) and also has a lot of apple sawflys. I had someone quote for sorting out the tree - he recommended cutting off 6ft all round to make it a tidier shape, said it had to be done now before the sap rises as if done later tree could die - but the tree has a few buds already so has the sap not already risen so to speak! He also said to block up the holes the sawflies are in with cement which sounds a bit mental to us. incidentally all for £160 which seems quite a good price but is this the right thing to do? It's a lovely old tree that produces ooodles of wormy crappy apples but we love it and would hate to see it go unloved.
