Hello Juankar, I only have the space because my children are all moved out of my house

As promised here is a small SBS on my evergreen trees...
I start with balsa wood trunk. You could use anything but balsa is soft and easy to carve and drill...




I prime the trunks black, then using your choice of bark color, paint the trunk. I use a wide flat brush with fairly thick paint and try to not fill in the texture. I brush against the grain like drybrushing. If nessary , a black wash of ink can be used to help the grain stand out...

The branches are 'caspia' found at craft stores in the dried flower department Great stuff with many uses!
Russ, I use the tips of the plant for the flowers.
The parts with no foilage on them make great dead branches for the lower part of the tree...



I spray the branches with cheap rattle can paint, as dark a green as I can find....

Holes are drilled in the trunk. I do angle the lower branches down and then change the angle as I go up the trunk.
This could depend on the type of tree you are building...




I then hand paint the branches the color of the trunk, I do not try to get them all, just the lower ones that can be seen.
My final step is to add some highlights using a light colored fine ground foam. I feel this gives a more scale look for 'needles'.

Certainly not oridginal or the only way but it works for me
