I am trying to root a piece from a pear tree. I put it in water and it is growing, but not rooting. I have had it in water for about three weeks. I have it in one of the bedrooms and it gets a lot of sun.
Root a Pear Tree

Unfortunately the probabilty of stems from a tree rooting is not verry good. Usually woody stock is taken at the correct time for that particular plant, prepared, dipped in the correct rooting hormone and placed in appropriate media, under mist, with bottom heat.
