See A Bag Of Dirt Tied To A Tree? This Is What It Means
Have you ever seen a plastic bag full of dirt tied to a tree branch? It might look like a strange repair job or an odd gardening mistake, but in reality, this is a centuries-old plant propagation method known as marcotting. It’s practical, smart, and used by gardeners around the world to clone plants without buying new ones. Here’s what it’s all about.
What Is Marcotting?
Marcotting, also known as air layering, is a way to grow a new plant directly from an existing tree or shrub. Instead of planting seeds or cutting branches, the method encourages roots to grow while the branch is still attached. Once rooted, that part can be removed and planted as its own tree. It’s especially useful for fruit trees, ornamentals, and generally hard-to-root plants.
Why Gardeners Use This Method
Believe it or not, marcotting gives you a stronger start than planting from seed. Since the new growth is still attached to the mother plant during the rooting process, it stays nourished and supported. This leads to a higher success rate and often faster growth once it’s planted in the soil. It also guarantees that the new plant will have the same traits as the original, which is important for fruiting trees.
How It Works
To begin marcotting, a gardener will strip a section of bark off a healthy branch, apply rooting hormone, then wrap it in moist soil or moss. That ball of dirt is kept in place with plastic or foil and tied snugly to prevent drying out. Over time, roots form inside the bundle, as the plant now thinks it’s growing in the ground. Once the roots are strong enough, the branch is cut below the root zone and planted.
When You Might See It
You’re most likely to spot marcotting on fruit trees or ornamental shrubs, especially in warm or tropical climates. Gardeners often choose branches that are healthy, flexible, and about the thickness of a pencil (they need a branch that’s still young enough that it can be ‘tricked’ into think it’s its own plant). The dirt-filled bag is left in place for weeks or even months, depending on the plant.

A bag of dirt tied to a tree might look odd at first, but it carries a purpose rooted (hah) in patience and skill. Marcotting is a smart and efficient method of growing new plants, especially when seeds or cuttings don’t offer the same reliability. If you come across one, someone in that area is doing some very thoughtful gardening.
