Cut some willow branches (All willow species produce this natural rooting hormone), into 2" or 4" long pieces (enough pieces to fill a bowl).
Put the willow cuttings into a big kettle (or pot) on the stove, fill with water (all cuttings should be are covered by water). Turn on minimum heat setting, cover with a lid, and leave on low (but do not boil) for 2 hours. Then turn off heat and leave kettle covered for 12 hours.
After the mixture has cooled for 12 hours, the water should be a dark brown. Strain out the water, and discard the branches. Pour the mixture into a container with a plastic top with holes pre-made, and just drop your cuttings in. Let the clones sit in the hormone for 12 to 24 hours (thus allowing the cuttings to fully absorb the rooting hormones), then plant into your medium.
Use as much rooting hormone as you require, then discard the used portion. The unused hormone can be stored in the ice box for years
