Why Draw a Tree at All?

You do not need to be an artist to get something out of this. Drawing a tree asks you to stay with one thing for ten minutes, and ten minutes is a long time in a wood. In that time you will notice the lean of a trunk, the way light comes through a crown of oak leaves, the shifting sound of wind in the canopy. It is the opposite of marching towards a viewpoint. The sketch is almost beside the point; the looking is the point.

British woodland rewards this sort of attention. Our trees are rarely symmetrical or tidy. An ash leans out over a hedge line, a hawthorn twists back on itself, a beech in a beech hanger grows straight as a mast because it is competing for light. These are the qualities worth catching, and they cannot be caught by hurrying.

The Kit That Fits in a Coat Pocket

The whole trick is to carry so little that you never leave it at home. A kit that weighs under 300 grams and lives permanently in your daypack will get used ten times more than a proper art bag you have to remember to pack.

• A5 hardback notebook. Hardback matters, because you will be drawing on your knee, on a log, or standing up. Look for paper around 120–160gsm so a light wash does not buckle the page.
• One 2B or 3B pencil. Soft enough to shade quickly, hard enough for fine branch lines. Carry a second, sharpened, in case you drop the first in the leaf litter.
• A small watercolour tin of eight half pans. Eight is plenty. A tiny tin forces you to mix rather than hunt for the perfect ready-made green.
• A water brush, or a No. 6 round brush and a screw-top jar. The water brush is easier in the field; the jar gives you more control.
• A scrap of kitchen roll or a cotton rag. For drying the brush and lifting colour from the paper.
• A small pencil sharpener. Obvious, but endlessly forgotten.

Trunk Shape, Branch Angles, Canopy Outline

Three things carry a tree's character, and none of them is leaf detail. Beginners tend to draw every leaf and end up with a green cloud. Instead, work in this order.

• Trunk shape. A trunk is not a cylinder. Look for the taper from base to first branch, the flare where the roots meet the soil, and the lean. That lean tells you which way the prevailing wind blows and where the tree sits in the light.
• Branch angles. Follow a main limb from the trunk outwards and note the angle it leaves at. Oak branches often kink and twist; ash limbs rise more steeply; birch forks early into a fine tracery. Draw the first three or four branchings, then stop describing and start suggesting.
• Canopy outline. Imagine running a pencil around the outer edge of the whole crown. That silhouette — rounded, ragged, wind-sheared, lopsided — is what makes the tree recognisable from a hundred metres away.

Spend as much time looking at the spaces between the branches as at the branches themselves. These negative shapes are usually more accurate than anything you invent, and they keep the drawing loose rather than fussy.

Working Fast: Two, Five and Ten Minutes

Quick outdoor studies teach you more than long ones, because they stop you fiddling. Try this progression through a single wood.

• Two minutes: the whole tree as a single shape. Trunk line and canopy outline only. No interior detail at all.
• Five minutes: add the trunk taper, the first three branchings, and one or two shadow shapes on the trunk side away from the light.
• Ten minutes: add a wash, a few clumps of foliage massed as shapes rather than individual leaves, and ground shadow under the tree.

Draw the same tree three times across a year — bare in February, in full leaf in July, gold in October. A small notebook of repeat studies quickly becomes more interesting than any single finished picture. Use the pencil at arm's length to check a proportion before you commit to it: hold it up, thumb on the trunk height, and compare that to the width of the canopy.

Adding a Wash Without Overdoing It

Keep your palette to a warm yellow, a cool blue, a red-brown and one dark. Greens mixed from blue and yellow are far livelier than a tube green, and a little red-brown added to the mix stops foliage looking like plastic. Apply the wash loosely, leaving patches of bare paper for light. Work on the sunlit side first and let it dry before touching the shadow side, or the two will bleed into a muddy grey. If a colour goes wrong, resist the urge to fix it. A note in the margin — "too blue, come back in autumn" — is more useful than a ruined page.

Making It Part of the Walk

Slot sketching into walks you already take rather than making it a separate expedition. Stop once on the way out and once on the way back. Sit on a stump, lean against a gatepost, and give yourself the length of one flask of tea. Five unhurried minutes in a bluebell wood in May will teach you more about how a beech grows than an afternoon of photographs. And it slows the whole walk down, which is the real reward: you arrive home having actually been somewhere, rather than having passed through it.
