My white lilac tree has flowered but produced no leaves this year! It didn't seem to be doing too well last year either, but is worse this year. Once the blooms have died, the whole tree will look like it does in winter with no leaves! What is happening please and is there anything I can do to cure the problem? Up till now, the tree has been beautiful....I've had it for around 12-14 years now. Thanks.
