Question

what can we use as natural rooting harmone​

Answer 1

Answer:

A small amount of apple cider vinegar is all you need to create this organic rooting hormone, and too much may prevent rooting. (Vinegar for garden use actually includes using apple cider vinegar to kill weeds.) A teaspoon of vinegar in 5 to 6 cups (1.2-1.4 L.) of water is enough. Any type of apple cider vinegar at your local supermarket is fine.
