Aging a Stone Wall or clay pot with Moss and Lichen

 

There are many recipes for encouraging moss on a wall or other object, including coating with buttermilk and submerging in a mucky pond for the summer. Some formulas call for mashed slugs, potatoes or grass clippings.

It is important to remember that moss will only grow in moist and shady places, and where it would grow naturally - and never in areas like a sun baked driveway or a plastic pot.

To grow moss on a clay or stone surface make a slurry of bits of live moss (from a nearby source) and some sort of agent that will help the mix adhere, and help the moss to thrive. Mix yogurt, buttermilk and water in a bucket with the moss. (Many people also add cow manure to this mix). After mixing the ingredients together, paint liberally on surfaces. Modeling clay may be added to help hold the slurry in place. Mist surfaces regularly to ensure moistness and keep in a shady spot.

Rough, porous surfaces with nooks help give moss, ferns, small flowers and lichens a foothold. Bermuda coral is ideal for this project. Regular concrete isn’t porous enough. Lichens are a union of algae and fungi living in a symbiotic relationship. They may be transplanted (move the lichen bearing object) and replace or duplicate their original environment. Lichens like sunnier, drier conditions than mosses.

Colonies of moss and lichens enhance the beauty of stone and brick walls.
