  20. Limestone is a porous stone that if kept moist can create a suitable environment for lichen, mould and moss to establish and grow. If the growth is not removed in its early stages it may darken as the mould spores die off. Dark soils, peat etc can also discolour the stone over time if it is not sealed. Sealing the stone with a good sealer will help to prevent discolouration.
