My fukien bansai had to be left as I had a trip. When I returned 5 days later it appeared completely dead. I had read on a blog about checking the soil of a new plant, but had been afraid to tamper with it. Now I felt I had nothing to lose. I removed the tree and the soil was rock hard. I scraped all of it out of the pot and put some gravel in the bottom, trimmed the ragged parts off the roots and replaced the soil with sand, soil, and mulch. I soaked it with water. The leaves are starting to come back out. I am going to start feeding it and hope for the best. If this works I can thank your blogs, as I am completely clueless.
