How to Paint Trees in Watercolor: Simple Shapes to Texture

Phase 1: Observation & Shape

Without understanding the skeleton underneath, you can't paint a tree that looks convincing.

Step 1: Stop Painting Leaves

Don't try to paint every single leaf. That's a fast track to frustration.

Looking at a tree, your brain automatically wants to pick out individual leaves. Fight that instinct. Instead, see the canopy as one big shape made up of clusters.

Think of it like painting hair. You don't paint every strand. You paint the mass, then suggest strands with a few strategic marks.

Same with trees. Paint the overall shape of the foliage first. Details come later - if at all.

I've seen people spend an hour dabbing tiny leaf shapes all over a tree, and it ends up looking stiff and overworked. The trees that look alive? Those are painted loose, with just enough information for your eye to fill in the rest.

Step 2: Isolate the Shape

Use the viewcatcher to frame a tree outside or in a reference photo.

This simple tool cuts out everything except what you're framing. You're no longer staring at a tree in a yard with a house, fence, and mailbox competing for attention. Just a shape.

Hold it up. Shift it around until one tree fills the frame. Study the silhouette. See where edges feel crisp and where they blur. Notice the negative space - those gaps between branches where sky cuts through.

This is what you're painting. Not a "tree." A specific shape with specific edges and specific holes.

Seeing it as a silhouette makes it way less overwhelming.

Step 3: The "Y" Structure

Trees split as they grow upward.

Trunk divides into main branches. Main branches divide into smaller limbs. Limbs divide into twigs.

Sketch this lightly before you start painting. Just the trunk and the main branches. They need to taper as they rise. A branch can't stay the same width from base to tip. That's one of those giveaways - branches that look like rigid poles instead of living wood.

Think about actual growth patterns. It splits. One becomes two. Two become four. The splits aren't symmetrical. Some branches angle sharply, some curve gently.

Get this skeleton right and the rest becomes easier. The foliage sits on this structure. Bark follows its contours. Everything else builds on this framework.

Phase 2: Texture & Trunk

Now we're laying the foundation - the part that anchors the tree to the ground.

Step 4: The Dry Brush Technique

Load your brush with dark brown or grey from the watercolor kit. Wipe most of it off on a paper towel.

The brush should feel almost dry. Just a trace of pigment clinging to the bristles.

Drag it sideways across the paper where the trunk goes. The pigment grabs the texture of the paper and skips over the low spots. Instant bark.

This technique feels almost too easy for how well it works.

Mistake to watch for: brush too wet. Too much water just gives you a solid brown stripe. You want that broken, ragged texture. Nearly dry does the trick.

Mess it up? Let it dry, then layer another pass on top. Watercolor forgives.

Step 5: Anchor the Roots

Trees don't float.

You'd be surprised how many paintings I see where the tree just... ends. The trunk hits the bottom of the paper and stops, and it looks like the tree is hovering.

Paint some ground around the base. A wash of color that ties the trunk to the earth, or a shadow pooling at the roots.

Light source established? Add a cast shadow stretching away from the base. Doesn't need detail. Just enough presence to say "this tree is planted."

That small addition makes a huge difference in how grounded and believable the tree feels.

Step 6: Varied Browns

Don't use one flat brown for the entire trunk.

While the trunk is still wet, drop in some blue or purple on the shadow side. Let it bleed and mix naturally.

Trunks aren't uniform. They have warm patches where light lands and cool pockets in shade. Moss clings to shadowed bark. Different moisture levels shift the color.

Mix it up. Burnt sienna where light hits. A touch of ultramarine or dioxazine purple in shadows. Let the colors blend on their own.

And vary your edges. Not every line should be sharp. Soften some, especially where trunk meets ground or where branches fade into leaves. Mixing hard and soft edges looks more organic.

Phase 3: Foliage & Light

This is where the tree actually starts looking like a tree.

Step 7: The Sponge/Stipple Method

Grab an old brush, a stiff synthetic brush, or a natural sponge to dab foliage on.

Load it with your green mix. Then tap it lightly on the paper in clusters. Don't fill every inch. Leave gaps. Keep it airy and irregular.

Vary the pressure. Some dabs should be heavy and saturated. Some should be light and barely there. That variation creates depth - some leaves feel closer, some feel farther back in the canopy.

Skip the broccoli trap. That look where the tree turns into a pile of identical green lumps stacked up. Real canopies have irregular clusters with different sizes and spacing.

Also - hold your brush at the end of the handle, not near the bristles. Less control equals looser, more natural marks. Weirdly enough, trying less hard makes it look better.

Step 8: Sky Holes

This is the most important step for realism, hands down.

Leave gaps in the canopy where the sky shows through.

Without sky holes, your tree looks like a solid mass sitting on top of a stick. With sky holes, it suddenly has dimension and lightness. It feels like you can see into the tree instead of just looking at the surface of it.

The shapes of the sky holes matter. They're not perfect circles. They're irregular organic shapes - some narrow, some wide, some where branches cross and create negative space.

Don't fill every gap with paint. That's usually when people overwork it. Step back. If it feels heavy, you need more sky holes.

Even now, I catch myself wanting to add more foliage. But holding back is what lets the tree breathe.

Step 9: Light Source Logic

Pick where the light's coming from.

Light from the upper left? Left side of the canopy gets warmer and lighter. Right side goes cooler and darker.

Warm side: mix yellow into your green. Think sap green with a touch of cadmium yellow.

Cool side: mix blue into your green. Think viridian or phthalo green with a bit of ultramarine.

This temperature shift creates depth. Your eye reads it as volume and form, not just a flat shape.

Even if you're painting a whole forest, this logic applies. Trees closer to the light source get warmer greens. Trees in shadow or farther back get cooler, more muted greens.

Step 10: Different Species

Quick shape logic for different tree types.

Oak and deciduous trees: Think "cloud" masses. Paint foliage in layered, rounded clusters. Picture cumulus clouds stacked together. Some brighter, some deeper. Sky holes cutting between them.

Pine trees: Zigzag or downward sweeping strokes. Begin at the top with a tight cluster, then work down in layers that widen as you go. Leave a small gap between each tier. Pines look more angular and structured than deciduous types.

The first time I painted a pine, it looked like a sad green triangle. Took me a while to realize I needed to break it into layers and let some trunk show through between the branches.

Fall trees? Warmer palette - oranges, reds, yellows - same cluster logic applies.
