I am a proud owner of what seems to be a 30 year old or so Serissa
Japonica
in slight semi-cascade / slanting style.

I won't comment too much on the age of the tree, but what makes you think
it is
30 years old? What is the trunk caliper? The correct name is Serissa
foetida.
The species originated in China.

I probably overestimated its age. Its probably only 20 to 22 years. I can
post a picture in the gallery if you are interested.

Currently the tree is in a plastic pot with a good amount of healthy
white
roots wrapped all around. The root mass does not seem to be too
overcrowded
yet. The tree is about 15" tall and it lives in a 10" pot. Upon watering
the
tree it took a good amount of time for the water to appear in the drainage
tray.

From your description, I would say the pot is about the right size, but
the
tree is badly in need of repotting in a better draining soil.

I plan to mist the tree in the morning for added humidity.

This will not help significantly. You need a humidity gauge, and possibly
a
humidifier.

Thanx for your suggestion. It actually happens that I do have one. I am
assuming that I can pick up a humidity gauge in the local Radio Shack.
What's the recommended humidity percentage for this species?

inside it will stay until I buy a house. I do have ample amount of
sunlight in the apartment. But I have read conflicting opinions on the
type of
sunlight the Serissa desires. Most seem to suggest that it likes medium
and
indirect sunlight.

You should try to make arrangements to keep the tree outdoors in the
summer.
Outdoors, Serissa likes just a little shade. Indoors it should get full
sun.
Under fluorescent lights is even better. What is more important, try to
keep it
cool.

Does anyone residing in the Northeastern part of US have experience
with
this tree?

I have killed more than my share.

would it be safe to transplant and root-prune the tree in a few weeks?


Wait until the weather is warmer & it is acclimated to your conditions.

Oh, and how bad is the "wretched" smell produced by root-pruning?

It smells like a slightly spoiled radish. I have smelled worse.

Thank you very much for all your suggestions. I will definitely wait to
transplant and prune the tree until it becomes more acclimated to its new
environment.
