After learning about how cool moss graffiti is, I decided to learn how to do it on my own. So, here is what I have learned and I want to share it here.
Instead of using toxic paints and chemicals to paint graffiti on your outer wall, why not try moss? Moss graffiti is a form of wall painting that uses living moss to create an eco-friendly design.
First, plan your project.
First you need to plan your project. Select a wall to paint on that’s somewhat porous where you have permission to do your graffiti. Surfaces that are painted or sealed can sometimes work, although they’re less than ideal. It’s harder to get the moss to grow on these sealed surfaces, and when it does grow it will often damage the paint.
Second, gather your moss.
Moss comes in a variety of species and types. Moss that grows on ground may not always grow well on stone and walls, so find moss that grows on rocks and stones. Once you about a handful, rinse it under cool water to remove as much of the dirt and mud as you can.
Make your “Moss Milkshake”.
In your blender, combine the moss with two cups of buttermilk or unflavored yogurt. Add 2 cups water and ½ tbsp. white sugar. Blend it until it’s completely smooth. If it’s a little too runny, you may want to add a tablespoon or two of white corn syrup to thicken it up.
Paint the Wall!
Some people will simply use a paintbrush and freehand their design on a wall. If you’re looking for something a bit more formal, you can use stencils, but sometimes it takes several applications of moss milk before it really takes off. Depending on the surface you’re using, you might trace your stencil with a ballpoint pen before you begin applying the moss; that should last through at least two applications of moss milk.
Making it Grow
At least once a week, you’ll want to check on your moss graffiti. Spray it with a water bottle to get it growing well. The first few times, you may want to add an extra layer of moss milk to help it thicken up.
For Best Results
Slugs love moss, so moss graffiti works best on surfaces that aren’t on the ground or near the ground. If the slugs start eating at ground level, they’ll climb up to get to the good stuff! For best results, plant your graffiti in the spring or fall in a moist atmosphere with partial sunlight. If you mess up or need to “erase” something, lemon juice or lime juice can be used to kill moss.
As with any forms of graffiti art, you’ll need to make sure you have permission from the property owner before you begin. If you’re concerned about the environmental impact of moss graffiti, it might be best to purchase moss from a nursery or plant store rather than taking it from its wild, natural environment.
