County Gate tree making
Hi folks, I am a new boy here but this is how I model broad leaved trees.
For prime broad leaf trees near the front of the model, we are now using a method using sage brush or heather as the armature with sea moss. Such trees are very delicate and should be placed where they are not likely to be damaged by folks playing with the trains! We have been very lucky to have a kind US trucker who collected sagebrush for us from the Nevada desert. I have noticed that there is a very similar plant to sage brush higher up on the hills of the Canary Islands, so for Europeans, next hols you can get gathering!
Materials
Sage brush, heather or any other well shaped woody plant stem
sea moss
PVA glue
spray mount and fixative
scatter material
Clothes pins or small clamps
Tweezers
Straight pins
Side cutters
Description of Materials
The trickiest part of making this type of tree is finding the correct materials. Sage brush or heather can be found simply out in nature. They should be put in a microwave and 'baked' for a few minutes to kill off any fungus, bugs, etc.
Spray mount is by far the best spray glue for this application. Spray fixative, used by artists is far better than hair spray for finally fixing the foliage.
I use Woodland Scenics medium green coarse turf to add 'leaves' to the trees or other scatters from Greenscene, which I am now beginning to prefer.
A pair of clothes pins or a small clamp works well to hold the armature while working with it. When connecting two clothes pins in an L fashion they also serve as a convenient stand to keep the tree upright when drying.
A pair of tweezers helps out a lot when trying to attach sea moss to the branches with PVA.
At the base of each tree I fit a straight pin in to help hold the tree in place when 'planted' on the layout. After the pin is stuck in the end is clipped off with a pair of side cutters.
A simple pair of side cutters or anything else which will cut a straight pin will work just fine.
Some use polyfibre to create the foliage. I have given up with this method as now and again it shows and destroys the entire illusion. Sea moss (Teloxys aristata of the family Chenopodiaceae) continues with arborisation and is much more real. Here we are making a large old elm for Glenthorne meadow. Elm is a very brittle tree, so I have included some dead cracked branches and some parts which have had the attention of a tree surgeon.
Sagebrush Tree Construction Steps
Prepare the armature. Select a portion of sage brush which is typical of the species of tree you require. It is always a good idea to look at real tree species in winter. Stick a straight pin into the base of the tree to add stability when 'planted'. Clip the pin head off after inserting the pin.
Armatures can also be made using twisted wire. This is the preferred method if an actual tree is being modelled. Heavier wire is twisted together to form the trunk and this is attached to bundles of 3 amp fuse wire for lighter branches. The armature is soldered together, washed, and then coated in bark material from Treemendus. This can be carved to create texture. A combination of wire armature and sage brush off cuts can also be used.

Glue a small pieces of sea moss suitably trimmed to the armature starting from the bottom. In some cases, the sagebrush is drilled to take the sea moss branches. The positioning of the sea moss will give the tree species its distinctive shape.

Continue the process working your way from the inside and bottom of the armature to the outside and top. Continue until all desired branches have been covered with sea moss It is fine to leave some branches uncovered to represent a dead branch here and there. Spray the sea moss with spray mount now and again to further attach the branches.

Very lightly spray paint with black, so the original colours show through.
You may choose to add ivy growing on the tree trunk at this time
Over a bag or in some other environment set up to catch the overshoot, spray the sea moss with spray mount. Be careful to spray away from the main trunk and from above - try to spray in bursts instead of one constant stream.
Carefully and slowly sprinkle on the flock. Darker flock can be applied to the bottom side of the sea moss then apply some lighter to the top of the tree to give it a bit of a highlight. It is very important not to overdue the flock. You should still be able to see through the tree after the flock has been applied.
It may be possible to light spray paint the flock to obtain the right leaf colour.

Tap off the extra flock into a container.
Give the tree another light coat of fixative to help keep the flock in place.
Time taken to build each tree is around 4/5 hours.
