Japanese maples tend to be used, as this species of tree is traditionally associated with bonsai growing. However, as the art of bonsai growth has evolved, other forms of maple bonsai have come to the forefront, especially in the United States and Canada. When caring for a maple bonsai, you need to learn about maple trees in general. These are fired clays that hold their shape and absorb moisture well, which the roots can then feed off of. This is important as these soils have good drainage, which prevents root rot from occurring. As high quality fired clay tends to be absorbent, there is enough moisture to allow the roots to get what they need while the excess water drains away. Pot size is fundamental in the care of the banyan bonsai. As this plant is also named a 'strangler fig', a pot too big or situated with other plants can cause the bonsai to grow larger than you desire. As this species of tree can grow to cover over a kilometer of ground, the dwarf versions of this tree can be sometimes extremely aggressive in smaller pots. Many growers have witnessed a tree die within several days due to quick exposure to cold temperatures. If you live somewhere cold, it is vital that you store the Baobab bonsai somewhere the plant can remain warm throughout the winter season. In addition, the Baobab bonsai should receive no water at all during the winter, as watering them in winter will cause root rot and your plant will die. Caring for a bonsai involves a lot more than just watering your tree every now and then and watching it grow. Bonsais are works of art that require careful pruning and management in order for the tree to take the shape that you desire. When you first buy a bonsai, there are a few tools that you will want to keep on hand to ensure it is properly cared for. This can be done indoors, so long as the temperature near the plant remains cold enough that the tree does not come out of dormancy. This is particularly important, as a tree coming out of dormancy too early can cause problems. It is possible for ficus bonsai to be maintained year round, although this can damage some species of ficus.
