One aspect of this diorama which seemed quite important was making the olive trees, which, as said in the previous episode have a rather peculiar shape typical of century old trees.

Michel collected small forked branches which could be used as tree bases, the smaller branches being made of a plant known as Chenopodium Aristatum (Seafoam, Zeechium or Wormseed). This northern hemisphere plant is used in modelling for its more or less accurate tree shape. The trunks were created by gluing two or three branches together with UHU no nails glue (ref: 40135), which allows the base of the trunks to be sculpted with a small knife. The bark effect was achieved by painting with a wet brush before the glue dried.

The trunks are then completed with small pieces of Zeechium by drilling small 0.8 or 1mm holes in the trunks. The inserted branches are glued in place with wood glue.  

The last stage of the procedure is to paint the trunks a greyish brown colour with gouaches, dry brushing afterwards. The trees can then be coated in fine green tufts. Different brands of scenic flocks are available, the main goal however is to produce a non uniform green by mixing various colours together for variety.

Once complete, these trees shall find their place on the diorama and help complete that Portuguese look and feel.   

 

Not quite finished just yet. The trees have had their bases added and have yet to be painted. Note how the glue helps to give the caracteristical olive tree shape to the trunks. They are in the process of drying before the addition of the Zeechium.

The completed and distressed looking trees stand looking old and wise. Olive trees are traditionally planted in this region every seven metres apart, but today’s generation of growers plant a smaller tree in between.
