Clamshell Propagator Instructions

How to Use the Clamshell Propagator

Here are step-by-step instructions on how to properly use your Clamshell Propagator.

Step 1: Wound the Stem

Using a pair of pliers, carefully remove a one inch segment of the bark and cambium layer from the stem. Be sure not to go too deep. To make removal of the bark easier, score the stem using a knife or wire cutters.

Step 3: Apply Rooting Hormone

Apply rooting hormone around the exposed stem (where you removed the bark and cambium layer) using a brush.

Step 4: Place Soil Disks and Add Water

Place a soil disk in each clamshell. Fill each clamshell with water and wait 5 minutes (or until all water is absorbed by the soil).

Step 5: Attach the Bottom Stopper

Attach the bottom stopper (the plastic ratchet tie) around the stem about 2” below the exposed stem. This prevents the clamshell propagator from sliding down the stem.

Step 6: Attach the Clamshell Propagator

Carefully attach the two clamshells around the stem, on top of the bottom stopper.
