Moss Graffiti

via Instructables "Horticulturist's of the past came up with a brilliant recipe to encourage the growth of moss to age and add interest to their garden designs, this recipe can be used as an an environmentally friendly alternative to spray paint.

The success of the recipe itself can be very hit and miss and is very much dependent upon choosing exactly the right location and weather conditions; moss thrives in the damp and can most often be found growing near to a leaky drainpipe or rain-soaked wall. If you have difficulty finding the right climate in which to grow your moss, grow it indoors (where it can be frequently spray-misted with water) and transplant it outdoors as soon as it has begun to grow. This is what I have done in the example shown in this instructable.

RECIPE
*Several clumps of moss
*1 pot of natural yogurt or 12oz buttermilk (experiment to see which works best)
*1/2 teaspoon of sugar
*blender
*Plastic pot (with a lid)
*Paint brush
*Spray-mister
If growing your moss inside you will also need a seed tray containing compost."
"Mossenger is the brainchild of London-based artist, Anna Garforth. Inspired by guerilla gardening collectives, who aim to enrich dilapidated public spaces, and Andy Goldsworthy, a British artist who creates site-specific art installations from materials and tools found on site, Anna is currently working on an on-going moss street art project."
