Here you can see how I made the shrubs:

Hub  

       
Twist iron binding wire with a hand drill with strips of sisal rope in between.      Masking tape on the trunk of a small tree before covering it with wall paint.
       
Dipping the shrub in turpentine-based paint.                                                                     The sprinkling of the shrub with a mixture of grits from the model train shop.
       
Shaking off the excess grit from the shrub.                                                                          Three steps how to make small shrubs.
       
The result on the track. A small shrub in front of the Impreza.                                     A combination of different coloured shrubs.
