All seems well. A question has come up. Of my five Chinese Elms, two still have green leaves on them. Are there different types of Ulmus Par. that will keep their leaves green through the dormancy? Are these trees not dormant? The trees in question are in an unheated garage with temps between the low 20's and high 30's. They are near a north facing window. Everything looks fine but this confuses me! thanks Jay __________________ A Bonsai student living with his trees at N 44.37 W 77.49...

Jay,
There are indeed some varieties that hold their leaves. On this type of elm I clean all old leaves off in Jan. (So-CAl) What happens if you don't is you will get a new leaves on top of old and the old stands out as older, greener. and tattered,etc.
No big deal. The only thing is if you defoiliate to early you might trigger a new set of leaves too early. Now should be fine for you, I would think.

The trees that still have leaves may be cultivars or may have just decided to hang on to a few leaves for whatever reason. If they were outside the wind would have probably blown them off by now. You can clip them off as BN said or just let them fall on their own after the new leaves come in. All chinese elms will hold there leaves in warmer climates. Tony
