The churchyard covers an area of about 3.2 hectares and is still used for burials. The main area is to the south and west of the church overlooking farmland.

The older part of the churchyard is managed by controlled grazing and has relict, unimproved neutral grassland with a variety of common grasses, herb species and bryophytes. The tombstones, however, support an excellent lichen and bryophyte flora including some very unusual species.

Orthotrichum Ivella forms large buns on some calcareous tombstones; this moss is usually found on trees in the British Isles; although it is uncommon in Kent, it is certainly very rare on rock anywhere.

Lichen flora includes Haerratomma ochroleucum, Ochrolechia pareela, four species of Physcia and the very uncommon Solenspora candicans.

Over 70 lichen species and 27 bryophyte species were recorded recently.
