I am devastated!! I had a Ginseng Bonsai for about 4 years that my husband bought me. it has been beautiful for years. lots of leaves, lots of growth. Two weeks ago the leaves started turning yellow and then brown and all the leaves have died. in the space of 2 weeks. I have no idea why. Its in a window but not in direct sun. it gets watered about every 3 weeks, and it had orchids and african violets around it. that has been the same for years. Funny thing is all of the plants on that window are dying. any ideas or help would be appreciated.
