Hey Jeanne - sorry to read about your Bonsai loss! They need daily watering, is this how he killed them? Anyway, perhaps you will gather those you have and start againish, often Bonsai trees are forgiving and a lot tougher than we think. Time consuming though and another real joy in life I find. They are perfect patio plants and not really for indoors for decoration. Greenhouse indoors for protection yes but not as indoor plants. Well that's what I have found.
Remember the Karate Kid movie and Mr Miyagi's bonsai they replanted on the mountainside? I loved that scene. Anyway cheers for the nonce, Lestie
