here is my ficus root over rock progression..
i started this plant by a cutting about four years ago...
and converted it in bonsai about one year ago...
plant in plastic pot...cutting was taken by mother plant about four years ago..
after pulling it from the pot
a close view of roots..
i graved it in the pot with the rock for 10 months but the roots have not gripped the rock firmly so wrapped the coconut husk and compost around it and wrapped with plastic..lets see what happen ?
