How to Grow Moss on Buttermilk

Mosses add color and texture to rock gardens, stone walls and shady areas of the garden. A layer of moss transforms a plain clay pot into an aged relic that looks as much a part of the landscape as the rocks around it. Buttermilk provides both glue and growing medium for moss in the garden, helping the tiny new plants take hold on rocks or clay planters.

Collect moss from the woods or from your garden. Search for healthy green moss and gently pry it from the soil in strips or chunks.

Pour 1 cup buttermilk in a blender. Add a handful of your moss pieces.

Pulse the blender on low for several seconds until you have a lumpy moss-and-buttermilk slurry.

Rub the buttermilk and moss mixture onto clay pots and rocks in the garden. Slather the surfaces with a thick coating.

Set the rocks and pots in deep shade. Too much sun will dry out the surface too quickly and kill the moss.

Mist the moss daily with water until it is well established. The surface of your pots and rocks will produce a pale green bloom which will spread across the surface.

Grow Moss For Ground Cover With Buttermilk

Add roughly equal parts buttermilk and moss to a blender and blend until the moss is broken up and the mixture is roughly the consistency of a milkshake. This sounds like reverse gardening logic, but unlike most other plants, moss thrives in compacted soil. Add each mixture to a separate bowl or pitcher and pour them into different sections of the space. Drag a stick in a zigzag pattern where two types meet to create a slight swirl. Moss should begin to grow with a week or two. Mix 1 quart of buttermilk and 2 gallons of water. Add this mixture to a watering can and sprinkle it over the moss twice each year to keep the moss carpet lush. Blend some moss with the buttermilk before mixing it with water if you need to fill in some sparse sections of the ground cover.
