Wolf lichen, or wolf moss lichen, is the only known poisonous lichen species. This particular lichen earned its name because it was used for poisoning wolves. Lichen thrives in moist, cooler climates such as the northern United States and Canada. The only time of year to avoid planting lichen is summer because the spores will dry out before sufficiently replicating.
Combine the milk, flour, yeast, gelatin, algae powder and fertilizer in the kitchen pot. Gently warm the mixture while continually stirring. Remove it from the stove immediately when a boil begins. This mixture is a bio-active growth formula. The milk and gelatin create a waterproof barrier on the surface of the rock or tree for the wolf lichen. The flour, yeast, algae powder and fertilizer provide nutrients for the spores to grow and quickly multiply. If not using this mixture right away, place it in the refrigerator. The formula can be stored for up to two days.
Add the wolf lichen flakes and soil to the mixture when ready to apply it. Mix them into the liquid completely to ensure an even application.
Select a surface for the lichen. Lichen does best in primarily shady and moist places. Porous rocks are also useful, because they tend to retain moisture for longer periods throughout the day. For optimal growth, lichen tends to prefer the north side of rocks and tree branches.
Paint the mixture onto the surface. Avoid applying the mixture on a day when rain is expected. The area where the formula is applied should solidify and blacken within a matter of days. The wolf lichen will grow into full formations in roughly two years.
