Winter is coming – Realistic trees for wargaming and dioramas part I

Last time we looked at a simple method to make realistic wargaming trees using just seamoss, a bit of wood filler and foliage nets, but there are more advanced techniques that will yield even more realistic results suitable for the gaming table and a diorama alike. Naturally this comes at a price: the time involvement is much longer, as this project will take you about three evenings.

This time the tree of choice  is an old oak tree. We expand on the idea of utilising seamoss in first making a tree armature out of wire to have a sturdy set of main branches and then attaching seamoss to depict the finer branches closer to the top of the crown. Finally we will add the distinctive bark texture. This way we achieve a tree siutable for a winter themed gaming table or diorama. Foliage and further details will be added in part two of this tutorial, situating the tree more in a late fall landscape.

As always, some facts about oaks, materials required and step-by-step instructions will be provided.

Some facts about oak trees

Oaks are large deciduous trees that can grow to an impressive size, with a stem circumference of up to 12 metres. For our oak tree we will, however, go for some more modest dimensions, to make it compatible with both 28mm and 15mm and to not use up too much foliage. The genus quercus includes a variety of different species, but we will model the archetypical oak tree quercus robur, also called English oak or German oak.

The short-stalked leaves have characteristic lobes, while the fruit is commonly refered to as acorns. To get the leaves look right we will need to employ MiniNatur foliage nets. To save money and also show off the intricate branches the late autumn foliage seems to be a good choice.

The acorns provide a good food source for all kinds of woodland critters, so I decided to add a squirrel drey further up in the crown. On the naked tree we assume the squirrels are resting in their dwelling (even though they are active all year round), while the autumnal version will feature them sitting on branches. A drey is normally constructed out of twigs, moss and leaves on a suitable branch and has a diameter of about 30cm. The entry is located on its bottom.

Oak trees are long-lived and have wide-spreading crowns of rugged branches. Young trees have a smooth, green-grey bark, while older trees  develop a thick, brown-grey bark with deep vertical furrows. Given we model an old oak tree we have to sculpt the distinctive bark texture, as wood filler alone or comparable pastes will not yield the desired effect. Finally, the bark can also be lightly covered by moss, which adds a nice contrasting colour to the grey-brown bark. Here we need to use some very finely ground foam clusters or green pigment.

What you need

  1. A variety of sea moss twigs. The smaller, the better. We will use these to depict the finer branches further up in the crown.

    Pile o’Seamoss.
  2. A pair of small scissors to shape the twigs.
  3. About 20 pieces of thin wire, each about 20cm in length. We will twist them to get a tree armature. It is good to have different gauges at hand, to add some variety.
  4. Super glue to attach the twigs to the wire armature. Get some fast setting stuff here.
  5. Wood glue to cover the seamoss twigs for added stability.
  6. Acrylic caulking paste. With some added paint we will use it for the first layer of “bark”. You can also add some black tea to add texture. Just cut a used tea bag open and let the contents dry. Also works well to depict dirt or dead leaves.
  7. Wood filler to create a realistic bark texture and to give the seamoss even more strength.
  8. Acrylic paints: Black, grey, brown and white to paint the bark.
  9. Very finely ground foam clusters in a medium green. These can be bought, but you can also make them yourself. You need some Pigment Fixer to make them stay put.
  10. MiniNatur/Silflor late fall oak foliage net. The tree is rather big so you might need a good portion of a medium-sized bag, which costs 20 Euro. So while not the cheapest solution out there, it is hard to find a replacement that will look as convincing. If you go for a naked tree this is obviously not necessary.
  11. Acrylic mat gel, dried basil, finely cut seamoss and black tea for the drey.
  12. A selection of broad brushes.
  13. A heavy duty wire cutter.
  14. Garden gloves to protect your skin from the rather sharp wire ends.

How you do it

  1. Take the 20 odd pieces of wire and bundle them together. Fold the bundle in half and twist the closed to form a loop. This will be the roots (cut the loop open when you finished the other parts of the tree and twist the wire to form the roots).
  2. Go on twisting and shaping, once in a while separating a bunch of two or three strands of wire to form smaller branches untill you reach the crown. This is more of a trial and error procedure and it helps if you have a reference pic handy to guide you.
  3. Remove any dried leaves from the twigs and clean up the lower section if necessary.
  4. With some superglue attach twig after twig to the top of the wire branches. This is time-consuming, but will produce very realistic ramifications. use the glue sparingly, so that it hardens almost immediately. You do not want blobs. This also disqualifies using hot glue. It will thicken the branches too much and a realistic appearance cannot be achieved this way.IMG_6425IMG_6788IMG_6791
  5. When you are finished cover the entire tree in wood glue for added durability. I dilute it 1:1 with water and use a small spray bottle for this step. It helps if you also add a drop of rinse aid. Let dry.
  6. Onwards to the bark. For a rough first coat we use the caulking mixed with brown paint and a bit of water to bring to a consistency that you can easily spread it with a brush. Divide the mixture in two separate cups and add some black tea for a coarser texture to the second batch. Brush the paste on the armature making sure that the twisted wire disappears. Make also sure that you don’t brush on too much when you reach the upper branches. They should taper off. To hide the transitions between seamoss and wire use the caulking without tea. Let dry completely over night.IMG_6898IMG_6900
  7. With the help of some wood filler add some further texture to the trunk and other twigs in the lower parts of the tree. This also adds further thickness to them making the overall appearance of the tree more realistic and any remaining wire showing can now be covered up. Let dry completely.IMG_6902
  8. Using a pointed sculpting tool or a needle carve the bark texture into the wood filler. The caulking provides a good basecoat for the filler, so it won’t crumble during this process and you can also not go all down to the wire. Remove any filler powder with a brush when you are finished. To bring out the texture and check how it looks I gave the trunk a brown wash.IMG_6904IMG_6911IMG_6912IMG_6913
  9. Now it is also time to add the drey. Mix some acrylic gel with dried basil, finely cut seamoss and black tea. Form a ball between your fingers and let it harden. You can also make a nice birds nest this way. Just make a ball and indent it with a round tip sculpting tool.IMG_6910
  10. Mix a brown-grey and paint the entire tree. It is much easier to do this with an airbrush, especially when you reach the finer branches. A spray can works, too.
  11. Mix a lighter shade of your base colour adding white and drybrush the trunk and thicker branches. Repeat with lighter shades until you achieve the desired look.
  12. Wash the trunk with a brown wash. I used Vallejo Umbra Wash.
  13. Paint the drey in a slightly different brown tone, wash it and drybrush untill you are happy with the result. Glue in a suitable place.
  14. Using the tip of your finger or a fine brush get some of the fine foam and rub it onto the bark. Some of it will remain in the recesses. Fix with Pigment Fixer.
  15. Tidy up the root section and attach the tree either to a base or make it free-standing with a magnet on its bottom. This way you can attach it to any terrain piece that is equipped with a magnet, too.

The lull before the storm.

The entire process will take you a good three evenings. Due to its wire skeleton the tree holds up well to the trials and tribulations of the gaming table, but naturally the fine seamoss tops are prone to breakage if handled roughly. If you add some foliage nets this protects the seamoss and will make the tree more resilient.

    1. Thank you! Much obliged. I’d say in the model railway community one does find quite a couple of tree obsessed people, given I always wanted one as a child it is only natural to come back to it now. 😉

    1. Hi, thank you for your comment. I bought it years ago back in Germany. Busch should still sell packs of it. In NZ I did not see any supplier so far, so maybe you have to order it overseas.

  2. I am really struggling to get the right color on my trees and yours look fantastic!
    What colours did you use to get the brown-grey color from step 10?
    Thanks!

    1. Hi Andreas,

      thank you for your comment. I use Tamiya Flat Brown as a base colour and add some grey. I basecoat the entire tree and then mix succeedingly lighter shades of this base colour for the drybrushing. depending on the tree you want to depict you might need to add more brown or beige to your base colour.
