Bonsai growing: Root Over Rock. How to grow (Part 1)
First of all you will need suitable rock (for, example, Japanese Ibigawa Rock); plant which can be grown in root over rock style (Ficus Microcarpa); scissors; branch cutters; Bonsai secateurs; knife and clean sand.
When the roots of the tree are long enough, cut off all unneeded leaves and wash all soil that is possible taking care not to injure the roots. Remove soil at first, and then wash with a usual garden hose.
Next, take the rock and your tree and place it over the rock. From here on, choose what positions will looks best. Do not place all of the roots in one place, as your bonsai should be viewed from different directions. Find the interesting part of the rock and put the roots of the tree into these cracks – so that the finished bonsai looks naturally. You can even bind thin and undeveloped roots, which can merge together.
