Grow bonsai myrrh and frankincense trees

My mother and I have taken this goal very seriously. She is the one with the green thumb and I believe that without her assistance we wouldn’t be as far as we are today. So far we’ve had lots of success germinating both species of plant however we have since lost all of the three myrrh trees that sprouted and maybe three of five Frankincense trees thanks to breezy windows and a faulty water softener. It seems Myrrh is perhaps the most picky of the two.
