Ingredients needed: Moist soil mixed with moss; 1 cup yogurt or skim milk; 2 cups water; corn syrup; 2 tablespoons sugar; a paint brush and a mixer.
Step one: collect enough moss. If you plan to apply it to the wall, it is best to collect moss from fields, roadsides or wet soil. Moss on tree trunks is not suitable for planting on walls.
Step 2: Wash the prepared moss, try to get as much soil as possible from the roots, and put the soil with moss into the mixer.
Step 3: Remove the yogurt or milkPut the fat milk, water, and white sugar together in a mixer and mix evenly until it looks like paint. If it is too thin, add corn syrup, and then transfer it to another larger bucket.
Step 4: Use a paint brush to spread the mixed slurry evenly Apply it to the wall, and check back every once in a while. If its too dry, add some water or apply some more mixed paste.
Tips: Try to apply it in a moist and sunny place. The best season is spring and autumn, which is helpful for moss. It grows well, and it is easier to grow when applied to a surface with small holes. If you want to remove it, just spray it with lemon water.
