you guys bottom cut part is very important to dip in melted Paraffin, it helps callouss which leads to rooting and prevents infections...think of an open wound on a body. you need to disinfect then protect with cover. So, disinfect (cinnamon tea-2 table spoons of Cinnamon in 1/2 gallon warm to hot water, steer and wait 5 min, then throw the cuttings in for 30 min or so...air dry) and Paraffin dip to seal for healing fast, keeps from dehydrating.
Robert, after cutting I wipe the cut end and make sure the bleeding (milk) stops then before dipping in hot paraffin I tap dry again with paper towel, it's important the surface of the cutting to be dry so the Paraffin sticks to it really well.
Paraffin coats the surface so thin that the roots or green growth never struggle to break the surface.
Igor, I'll check that Electrician's Liquid Tape product, I am interested to see how it works compared to Paraffin, as you should know by now, I am NOT pro-chemicals ;)
Jen, I tried candle wax before but Paraffin sticks better and it coats thinner layer. I'm looking to dip entire cutting in Paraffin, as soon as I find a suited vessel to melt the Paraffin in.
