Chinese Elm lost most foliage was created by Rodrigo

Posted 8 years 2 months ago #27389
Hello guys, first I must say I am a complete newbie; this is my first bonsai.
It is a Chinese Elm bonsai and it lost its foliage from the time of purchase (June) until now (November). Images attached.
Roots seem fine (i.e. not rotten). Image attached.
Is there something I can do (e.g. re-potting, pruning, feeding, wiring, etc.) to bring back its foliage?
The loss of foliage could have been due to overwatering in the past months.
Answers or any general advice based on the pictures are much appreciated!
About the bonsai: 7 years old (according to retailer (Amazon)); now it takes about 1 week to re-water (the necessary time for a chopstick to come out completely dry); it stays by a well lit window in my kitchen, where it's constantly 20C; humidity in the flat stays around 60%. I'm in Scotland, so days are getting shorter quickly.

Thanks AUK. I saw a bunch of Chinese Elm posts (here and elsewhere) before I posted my question, but I'm still not sure what I could have done wrong. Perhaps if I tell you about how I've been handling it (as well as inspecting the pics), you'll spot a mistake:
- Initially watered it every second day; since last week, I've been using the chopstick method and not watered it. I'm waiting for the chopstick to come out completely dry. The soil came to the point of building a white layer of mould, which I scraped off last week and it hasn't come back since.
- I fed it with a 4-6-6 feed every fortnight until last month; I haven't fed it for a month and Im planning to feed it monthly.
- I pruned it twice during summer; gradually during summer, it lost leaves and the thiner branches are quite fragile. this week I removed all branches that had no leaves or only 1 or 2 leaves on the tip.
- It's still in the same pot it came in.

Actually, it looks good, should have left it in the pot until spring . It will need a bigger pot to start the training, though. It's not not a bad start though.
you know they like being kept outside all year right? How far up north are you?

The best place for Chinese Elm is outside. They are tough so will survive for a while inside but you have found that they do not last long. It looks in reasonable condition, but the soil does sound as if it is not good. If you are planning on keeping it in then I would consider re potting now, but if you are able to put it out then I would leave it until spring. Have a look at bonsai4me.com for spcies guides and also some very good books.

Thanks. When you say "it looks good", even after losing >50% of the foliage, does that mean the loss of foliage is expected? Is it because of Autumn?
I am almost as north as North can be ;-) Aberdeen, Scotland. The problem is I live in a flat and I won't be able to place it outside.

Ok, well, then you will have to put up with it not living long. Next time get something that will survive inside. You need to get the watering right. Do not water to a schedule, check every day and water when almost dry. You could re pot now as it is going to remain in. Losing leaves would be ok if it was not inside, but it should not lose many. The conditions are not helping. Fertiliser is not doing any good either.

I'm confused... I did look up online and many websites say Chinese Elms do well indoors... Anyway, which species would you recommend for indoors?

Ok, this is what I'm doing now.

Ok, will try that. Does that include pruning roots and crown?

Ok. Sad to know I messed up somewhere, but good to know what to aim for from now on.

I read a low N fertiliser is best for indoor (could be wrong again). What NPK ratio do you recommend?
