Chinese Elm - normal leaf drop or tree in trouble?
After much deliberation, we planted a Chinese Elm as the focal point of our patio. It came in a 24" box, and since we planted it in March it has put out a lot of new green growth, upwards and outwards. I know that this is considered a semi-deciduous tree, and I'm trying not to get too alarmed as more and more leaves are turning yellow and falling to the ground. However, there are several Chinese Elms in our neighborhood that started off with the same leaf drop pattern, and are now almost completely devoid of leaves!
Is this normal for this tree? I love the quality of movement and dappled shade that it brings to our sitting area, and needless to say would be very sad to lose it. The leaves that have grown since the Spring seem to be hanging on (for now), but the ones that were on the tree when we planted it are yellowing.
Thanks so much for all and any advice and reassurance.
