I received a bonsai grape vine from my daughter for my birthday. I would like to accept the challenge/adventure. The instructions that came from Harry & David were very sketchy about watering frequency and fertilizing. As the plant arrived, there was a carpet of green moss on top of the soil. The moss has apparently died off. At first the plant was going great, then suddenly the leaves began to die off. I fertilized it with 2 "Miracle Grow" plant spikes and now it seems that there is new growth. Could you recommend a watering/feeding cycle? How about a good book, possibly taylored to grape vine bonsai?
