This is such a great idea! I have never seen them in stores before this year, and of course I HAD to buy myself one. Then, I found out my mother got one for her birthday in November :) Unfortunately, mine died shortly after bringing it home. Does anyone happen to know how to keep them alive?
I bought three this year. The first one I bought pretty early and accidentally let it get pretty dry. That had the most brown needles by Christmas. The next two I was more careful to give them frequent waterings. They did better.
My guess would be to give frequent small drinks of water, or sit them in a dish to soak up water briefly, to keep the root mass moist. I think mine got dried out and being so compacted, never really got re-wetted properly.
