[IBC] Winterizing Chinese Elm.
Standard Chinese elm is hardy in the ground in Zone 5, so it and 'Seiju'
should not be a problem in the Philadelphia area. However, 'Seiju' and probably other Chinese elm cultivars may not actually drop their dead leaves until January. If you are going to pack them up in a box or plastic for the winter, you need to remove all the dead leaves by hand first. My 'Seiju' winters in an unheated sun porch, so I can let the dead leaves alone.

Michael is totally right here. It is not worth risking ramification that
one has worked years to develop, or even the total loss of a tree, by skimping on winter protection. And, as we all know, USDA zone temps are averages, it can occasionally get much colder than the published numbers. Also, I am willing to bet that many, if not most, of us are growing bonsai that would not be hardy in our particular zones if they were out in the ground. For these trees good winter protection is essential. My main winter storage area is a cold frame. I have a temperature sensor in it, and it never gets colder than 25 deg. F, even when the outside air temp has dropped to -10 or -15 F. This allows me to confidently keep material that would never survive here without protection. A decent cold frame is not that hard to construct, and is well worth the effort when you consider the time and money we all invest in our trees. Regards, Roger Snipes Spokane, WA. Zone 5-ish ----- Original Message ----- From: "Michael Persiano" : There is no such thing as a "standard" when it comes to wintering trees. The question is: how much are you will to risk to the whimsicality of winter? For me, the answer is a resounding. "Not Much." ************************************************** ****************************** ++++Sponsored, in part, by Bob Pastorio++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?
