[IBC] Chinese Elm "Dwarf"
Hi Everybody
About three years ago I and some other members of or Club acquired some Dwarf Chinese Elms. The leaves of this species are similar to those of the Chinese elm expect they are tiny only 3 to 5 mm long. One variety has yellow margins and is sold as variegated. The plants are easy to propagate from cuttings. But when we transplant the rooted cuttings, most of them do not survive. Despite best efforts we could save hardly 5 percent. Same problem is encountered when its Bonsai is repotted. On the other hand, regular Chinese elm is very hardy and can tolerate all rigors. If anybody has some remedy please inform. Please also tell whether it is a hybrid and if so who are the parents or if it is a natural species.

The leaves of this species are similar to those of the Chinese elm expect
they are tiny only 3 to 5 mm long. What you probably have there is Ulmus parvifolia 'Hokkaido.' It is not a hybrid; it is a very dwarf cultivar. One variety has yellow margins and is sold as variegated. There are two or three variegated cultivars of Chinese elm. You would have to give us more information before we can determine which one. However, they all get about the same care. But when we transplant the rooted cuttings, most of them do not survive. Same problem is encountered when its Bonsai is repotted. Some of these cultivars are very fussy. If you want a dwarf Chinese elm that is easier to care for, try to get hold of 'Seiju.' Meanwhile, leave your rooted cuttings in the original bed longer before you transplant them, and try not to disturb the roots of the cuttings or bonsai when transplanting. I gave up on 'Hokkaido' because it is just too much trouble, but I love my 'Seiju.' After only a few years of training it looks like a real old tree. Another dwarf elm that appears to be foolproof is Ulmus xhollandica 'Jacqueline Hillier.' You will probably have to get both of these from US or Europe. I don't know if they are available from China or Japan. Iris, Central NY, Zone 5a, Sunset Zone 40 "If we see light at the end of the tunnel, It's the light of the oncoming train."

Anil: I cannot identify the cultivar, but I can give you advice. If you are repotting in extreme heat, you are going to constantly face this challenge. This particular Elm may not like to have its roots disturbed. You need to attempt to acquire a rooting hormone with gel. Such products are sold in the US, particular, Transplant 1- Step by Roots. If your club needs to acquire this product, let me know and I will help you find a source.

I have generic ulmus parifolia, Seiju, Hokkaido,
varigated, etc. I do cuttings like crazy and have little problems. One method I have tried for rooting cuttings and having them sit for a while is to root in a seed starting medium cut with pearlite or pumice. I recycle a glass jar from jam or pickles. I find a pot slightly bigger than the jar and use the jar as a glass bell. This way I can root the cuttings, take of th jar to harden off and wait a while to transplant (like a couple of years). Id do have my best luck though from root cuttings rather than top cuttings. A nice piece of Hokkaido broke off one of my trees. It is about 3/4' in diameter. It rooted with no problem. Now what I do have a problem with is getting cuttings of Hime Shara (stewartia) Repotted without dieing.

"The plants are easy to propagate from cuttings. But when we transplant the

" I transplant Chinese Elms in the spring, just before its growing season starts. Cutting that root are repotted at this time. I work with a few different varieties of ems. THe only variegated I work with is called Frosty. I also work with Seiju ,Yatsabutza, Cedar Elms, one more I received as a Seiju but is of another variety I am not sure of. I also try Catlins. to me catlins are touchy. There is a dwarf Elm called Niri. as well I guess you have to know when your trees go into a dormant period, if you have one in India. There is one Variegated Elm that I have great difficulty finding. It 's called Yuzin. In the spring the entire leaf is cream color almost yellow with white edges, it retains this color for about 3 weeks then the leave turns green with white edges. In the spring it is the most striking tree. even among some of the most colorful maples. I have seen it in a greenhouse among beautiful bonsai , but the Yuzin stood out every spring.
