When you are buying through a bonsai sale, most of the goods being sold will be a year old, possibly several years old. This is not typically a problem with bonsai supplies, as high quality supplies are designed to last a lifetime. This means that gear that has been on the shelf for a year or more will come to no harm and work just as well as their newer models. This variety of bamboo is hardy, and can be grown indoors or outdoors, provided that the bamboo is protected against frost. Like most species of bamboo, the plant does not thrive well in places where frost occurs. Frost damages the bamboo and stops its growth, often shocking and killing the plant. It is for this reason that many bamboo species cannot thrive in northern climates unless they are kept indoors. As the trunks of the tree have a layered appearance from the aerial growth of roots, it is not uncommon that designers will use this characteristic of the plant as a fundamental part of the finished piece. The aerial root system, if properly controlled, can enhance the appearance of the bonsai without risk of spreading beyond the confines of its pot or causing root problems in the pot itself. As the tree loses its leaves in the winter season, this characteristic is predominate during this time. In nature, the Baobab is at risk of going extinct due to predation from animals like elephants. Domestically, many people try to grow at least one Baobab bonsai in their collection due to their odd appearance. If you are interested in starting to care for and grow your own bonsai tree, there are several ways you can start. You can start by purchasing a tree that has already been designed. These trees are typically five to seven years old and have had their basic shape already tended to by a bonsai tree artist. As more people are entering the bonsai hobby, there are more varieties of trees suitable for indoor growing coming into the market. Before you purchase any bonsai plants, you will want to find a line between ease of care and ease of styling the tree. This will ensure that you pick the right bonsai plants for you.
