Scaring the cutting - scarification

We want as much chance of roots growing from our clone as possible, and one of the ways we do this is by scaring the stem where we want this to happen. By slicing away a thin layer of the outer stem we increase the surface area of places that may produce roots. Later this scar area is dipped in a rooting gel or powder containing hormones. This encourages root formation further.

Using a clean sharp blade (or I find one side of a sharp pair of small scissors work well) start about 6mm from the end of the cutting and slice away a thin layer. Be careful not to cut into the stem too far. As soon as you've done this the cuttings should be placed in a beaker or glass of water with the cut submerged  so they don't dry out. Spray the cuttings again with fine mist. Process a few cuttings like this until enough are done to move on to the next step. Don't cut too many though. Remember the quicker the time between taking the cutting from the plant to setting it in the grow medium the better.
