Why Grass Courts Need A Year Of Preparation

Grass is the only major tennis surface that is alive, and the only one that cannot be repaired quickly. Preparing a championship court is a full annual cycle with a very short performance window.

The growing season begins as soon as play ends

Once the tournament finishes, worn courts are stripped of damaged grass, the surface is scarified and new seed is sown into the existing soil profile.

Establishment takes months, and the young plants must root deeply enough to survive the compaction and abrasion of championship play the following summer.

Autumn and winter are spent building root depth rather than top growth, since a shallow-rooted sward tears out under the loads a sliding player generates.

Soil compaction determines bounce more than the grass does

The playing characteristics come mainly from the ground beneath the leaves. A firm, heavily rolled soil profile produces the low, fast skid the surface is known for.

Rolling continues through spring, gradually consolidating the profile so that it reaches maximum firmness at the start of the tournament rather than before it.

Moisture content is controlled tightly throughout, because a soft court plays slower and higher, and a court dried too far becomes brittle and breaks up under foot.

Grass species were chosen for durability

Championship courts moved to a hard-wearing ryegrass mix, selected for its resistance to wear rather than for speed of play.

The change made courts survive a fortnight in better condition, particularly on the worn areas behind the baseline where most damage concentrates.

A side effect was a slightly slower, higher bounce than earlier surfaces produced, which contributed to baseline rallies becoming more common on grass than they once were.

Wear patterns are predictable and unavoidable

Damage concentrates behind the baseline and around the service boxes, following where players actually stand rather than spreading evenly across the court.

By the second week those areas are largely bare soil, and the ball behaves differently there, skidding lower and occasionally deviating off a worn patch.

Ground staff cannot reseed mid-tournament, so late-round matches are played on a surface materially different from the one used in the first round.

Weather removes control that cannot be recovered

Rain softens the profile and stops play, and a court that has been covered and uncovered repeatedly plays differently from one that has stayed dry.

Roofs on the main courts solved the scheduling problem but created an agronomic one, since grass under a closed roof receives less light and different air movement.

Supplementary lighting rigs are used to compensate, which is an unusual requirement for a sports surface and shows how narrow the tolerances on a grass court actually are.
