How to paint trees and leaves with watercolor

This is a watercolor and mixed media landscape, I wanted to try painting a bigger sized watercolor but was limited by the size of my paper and the boards I had available so I thought painting a triptych was a way to paint bigger while keeping my process of mounting paper on board manageable. I also thought the interruption introduced by the 3 boards would add some rhythm to the existing rhythm of the tree trunks. For this painting I decided to use two different techniques : I painted the leaves directly, mixing the colors wet into wet for interesting effects and bright colors  and I used a layering technique for the trunks to have more control on color and tone variation.

Here are the steps you can take to paint a forest scene with watercolor

I started by mounting my paper on board, to see a step by step tutorial of this process, click here: Mounting watercolor paper on board

Once the paper was dry on the board, I transferred my drawing with a grid system.

painting light watercolor washes in the background

I start by painting very light washes on the background, painting around the tree trunks areas. I did not protect the trees trunks with masking fluid as it is relatively easy to paint around the straight lines of the tree trunks.

painting leaves with watercolor mixing wet into wet

I paint the background leaves, mixing colors wet in wet so the colors are mixing on the paper rather than on my palette and are producing nice textures and changes of color.

masking leaves

Before painting the trunks I need to protect the few areas where leaves are in front of the trunks, as it would take too much time to paint around.I paint over those leaves with masking fluid. I am also masking a few lines in between trees.

Let the masking fluid air dry as using an hair dryer would cause the masking fluid to adhere too much to the paper and make it difficult to take off.

Daler-Rowney Masking Fluid

This fluid is used to create striking white highlights or to mask areas for overpainting at a later stage. It forms a fast-drying, water-resistant film on watercolor paper and board, and is easily removed when dry.

layering watercolors

Then I can start painting the first layer of yellow. When layering watercolor, it is always a good idea to start with yellow as it is the less transparent color I am going to use.

painting the blue layer on top of the yellow layer

Once it is totally dry I continue layering the primary colors, painting now a blue layer ( Prussian Blue).

It is important to let color dry completely when layering watercolors as you will get a glowing effect that way.

Then I paint a layer of red, using the Holbein Permanent red.

layering many watercolor washes to paint the tree trunks

The next step is to paint more layers to adjust the colors until I am satisfied with the final color. I added many successive layers, always waiting in between for the previous layer to be thoroughly dried, so the colors stay vibrant.

taking off masking fluid

I the take off the masking fluid on all the paintings, it is leaving very hard edges that would look unnatural if left as is.

softening masking fluid hard edges with a stiff brush and water

To soften those hard edges left by the masking fluid, I will use a very stiff brush and a bit of water. This is an old brush that I did cut closer to the ferrule so it stays very stiff.

softened edges

Once I did soften a few hard edges, I let the painting dry before going to the next step.

Splashing and splattering with watercolor washes.

splashing with colors and gouache

Finally, the last step is to splash the watercolor and add some drips, the fun part!
I am using a wash of yellow and red and some of the cobalt blue mixed with China white (gouache) as I like the milky appearance it is adding to that blue. Some of those colors will mix on the paper.

splashing with watercolor and gouache

To achieve an even and continuous splashing effect, I lay the triptych panels side by side on the floor and start splashing. I will also lay the panels at a 30 degrees angle and add some drips along the trunks.
