Lichen Growth FormulasHow to Grow Lichens
The lichen lovers have tried a lot of lichen growth formulas. The most successful and easy to implement are listed on this page. We recommend one application a year near the beginning of a rainy or snowy time, but if you've missed damp weather go ahead and apply the growth formula anyway.
Formula 1 (Traditional)
The first method we tried, and the most commonly practiced lichen growth formula is to spray or paint milk, yogurt, or rice water onto the surface where lichens are desired. This will usually darken the surface in a matter of weeks or months, and within a few years many lichens often appear. We prefer fresh milk in a spray bottle for the ultimate ease of application.
Formula 29 (Magnificent Lichen Growth Formula)
Mix the following together and bring to a boil stirring frequently:Purpose of Ingredients
The proteins in milk interact with Calcium in the environment, in the soil, and in the rock to form a somewhat waterproof glue to hold the mix in place.Choosing a location
In addition to nutrients lichens require light and moisture for growth. Lichens tend to grow best on rough porous surfaces that retain moisture. In northern latitudes the north facing sides of objects tend to support lichen growth much better than south facing sides because they remain damp longer after dew or rain. Cracks and crevaces are also favored places for lichen growth because of the increased dampness.Other Formulas
