The Knot Garden: Geometry in Miniature

Before the English formal garden became grand, it was small. Tudor and Stuart manor houses were often surrounded by a knot garden: a square bed, rarely more than four metres across, laid out in interlacing ribbons of clipped box, santolina or hyssop, with the spaces between filled by thyme, winter savoury, marjoram and violets, or by gravel in two contrasting colours.

These gardens were rooms outdoors. They sat close to the house, enclosed by a wall, a trellis or a raised terrace, and they were meant to be read as much as walked in. The knot was a symbol of order, its geometry echoing the squares and proportions of the house itself.

A knot is generous to a small garden. Four metres square is plenty, and a simple double loop with four corner repeats reads better than an overcomplicated design. Clip twice a year, in late May and early September, to hold the edge.

Parterres, Terraces and the Long Axis

Through the seventeenth century the scale changed. As houses gained first-floor galleries and formal fronts, gardens grew symmetrical and axial, and the parterre in front of the house became far wider than the knot: a sheet of clipped box scrollwork set on coloured gravel, best seen from an upstairs window, where the pattern resolves into a whole.

The vocabulary of these gardens has shaped most formal gardens since:

• Terraces — raised walks on one or more levels, linked by stone steps and balustrades.
• Long walks and avenues — straight lines of lime, elm or hornbeam aligned with a doorway or a church tower, their whole point the vanishing point at the end.
• Clipped evergreens — yew cut as cones, pyramids and spice-jar shapes, standing like sentries along a path.
• Walls with a view — boundaries pierced by a doorway framing a field, a church or a distant hill.

Water, Statuary and the Grand Manner

No formal garden of the period was complete without water, moved but not wild. A canal gave a long mirror of sky and a straight line to the horizon; a rill ran a thread of sound along a terrace; a fountain or a pair of basins marked where two paths crossed. Water was ornament and utility both, feeding fish ponds and draining wet ground.

Then came the ornament. Lead statuary was produced cheaply — gods, shepherds, sphinxes, urns — and set on plinths at the end of walks, giving the eye a resting place. A pair of gateposts crowned with a ball, a flight of stone steps down to a canal, a sundial set true on a south wall: these small pieces do more for atmosphere than a whole summer of bedding. Buy one good urn rather than five mediocre ones, and put it where a path turns.

The Landscape Park and the Retreat from Formality

By the early eighteenth century taste turned against all this. The landscape park became the fashion: sweeps of grass running up to the house, clumps of trees, a serpentine lake, a belt of planting around the boundary, and a ha-ha — a dry ditch with a retaining wall — that kept livestock out without a fence interrupting the view. Close to the house, parterres and terraces were often simply flattened.

Geometry did not vanish; it moved to the edges of the picture: the walled kitchen garden with its espaliers and fan-trained fruit, the avenue that announced the drive, the forecourt where carriages turned. If a manor house today has a strangely empty front lawn, a formal garden probably stood there once and was deliberately removed.

The Victorian Revival and the Garden Today

The nineteenth century brought formality back, first as bright carpet bedding, then more lastingly as a series of garden rooms: a yew-hedged rose garden, a paved terrace, a step down to a lawn, a sundial, a rill. This is the tradition most of us inherit, and it is a forgiving one.

One practical caution: box blight and the box tree moth make large box plantings a gamble. For structural hedging, yew is slower but bulletproof; holly, lonicera nitida, rosemary and teucrium all clip into useful low shapes. Mix species rather than committing to one.

Keeping the Bones in Order

A formal garden is a commitment to clipping, so plan for it before you plant. Leave at least a metre and a half between hedge and path so you can work both sides, and keep paths a generous metre wide so a barrow passes easily. Cut yew once a year in late summer, box and its substitutes twice. Then place one bench where the whole design is best seen — because that view is what the geometry was always for.
