Hello Jackie,

It sounds to me like you are experiencing a common fact about bonsai.....you are going to read a lot of contradicting facts about Bonsai! Everyone is going to give you a different answer about the same subject. Thank God that bonsai has a basic truth about it's cultivation. Here is what you need to know.

About repotting: Everytime you repot a tree you shock it. If you did any root pruning then the level of shock was more intense. If you recently transplanted the elm, then leave it alone for a while and be careful to only water when it is slightly dry. You can observe this by sticking a toothpick into the soil and checking every other day or so. When the pick is drying out then it is time to water. For now, let the tree rest and you will see it producing new growth sooner or later. Also, since the roots have been disturbed, they will not be absorbing as much water. This is why it is best to mist the elm so that it can obtain the water it needs through the leaves.

About the soil: I have never heard of "bonsai compost". In fact, i would think traditional bonsai soil mixes and compost contradict each other. Bonsai soils tend to be fast draining while compost retain much more water for longer periods of time. The ficus can grow in many different soils, but the elm might not like so much water retention. The next time you repot, use more of an inorganic mix. I use a mix of equal parts turface, lava rock, and pine bark.

About location: As soon as the temps warm up you need to place the tree outside if you can. Sure elms can be semi-deciduous, but even indoor bonsai benefit a lot from staying outside during the warmer months. Especially in your elms condition, it will need a more natural enviroment to get well faster.

Hope this was some help.
