Hi,
I have this bonsai for four years now. I keep it indoors, but by a huge eastern window (4.5 meters wide, 2 meters high), 20-25 degrees Celsius. I keep it's soil wet. I spray it with water every day. I feed it with a proper bonsai fertilizer, according to the elm's needs. During the winter (December - February) I keep it in a low-temperature basement (about 5 degrees Celsius, but never 0), when it loses its leaves. By the end of this resting period, my elm awakes by itself with new leaf shoots and then I take it back to my eastern window. Bonsai quickly went full green and during March and April this year it was beautiful as never:

I have replanted the elm in early March to a bigger pot and a special mix of soil prepared especially for elms. It grew perfectly. In May, however, leaves started to go yellow and new offshoots (while still growing rapidly) started getting curled, brown and eventually dead:



I did spray the elm two times with synthetic anti-pest. I thought that I burned the shoots, but ones which hadn't existed at all back then are dying now, and it was like 2-3 weeks ago. Bonsai was "washed' with water many times since then. I occasionally see a sciaridaes flying around (I see like one-two a week and I kill them), but I heard that small amount of them is not dangerous. So, any chances someone knows what happens to my elm? It looks like it is dying now, despite it is full spring here.
