Cuttings are to be selected from healthy parent stock only take a cutting from non-woody stems if possible take at least 25mm or 1 inch more than required immerse the cutting in water make a cut with a sterile razor or scateurs whilst underwater just below a branch By cutting underwater you eliminate air bubbles forming at the incision and blocking the rooting process. make this cut diagonally (about 45 degrees) to the stem (still underwater) cut off the branch just above the first cut to provide another surface for roots to strike (still underwater) Gently scrape the stem for 25mm above the cut to disrupt the cells on the stem (still underwater).
Use the sip of life technique for hard to propagate cuttings by using an extremely sharp razor blade to puncture the stem about 25mm from the base of the cutting. This puts a small amount of water into the stem and must be a very thin cut, as the incision must close itself up when you withdraw the blade. The cutting will now suffer less dehydration whilst rooting.(still underwater) remove the cutting from the water (Optional) dip cutting in a root rot treatment to avoid stem rot during rooting dip the cutting in a rooting hormone, preferably a Gel, or a Liquid and stir around for 15 seconds. Powders can rub off. Place in Perlite and Vermiculite Mix or a Rockwool cube, and keep the medium moist. Dehydration is the major cause of cutting failure because there are no roots to replace lost moisture. Best strikes above 20 degrees Celsius. Up to 30 degrees Celsius.
Mist the cuttings with water to stop dehydration (and a vitamin B solution such as Superthrive if available) Using an aquarium as a mini-greenhouse keeps dehydration down to a minimum. Small clear Propagation shells are available with vents designed for this purpose at Hydroponic Stores.
A Cutting will usually live or die within the first 3 days (72 hours) Use up to 24 hours of low light intensity (such as Fluorescent light) to ensure photosynthesis is still occurring, but not so bright as to cause dehydration. After the cuttings appear to be rooting, vent the propagator to avoid stem rot or root rot from the high humidity. Remove the propagator after 1 week if all is well. When in doubt, ventilate the mini-greenhouse but use warmth and keep some humidity in the propagator for as long as you require to confirm they have survived.
If your mother plant is from seed, it should be at least 1 foot tall. But if you need lots of clones, let it get big. It pays to have patience sometimes. I can always find the room for a bigger plant.
