Oh no. I didn't remember that you said June or July. I did it today. I was just so excited to go out and try it. I bought coarse sand instead. I bought root hormone powder type. My dad cut me branches that are like almost 1 inch think. I tried it on a michelia alba tree. I haven't tried it on the ochna so I will wait until June for the ochna serrulata. My dad cut me 2 big branches. It looks like a 2 foot tall tree. Will it still root or should I go and fix it to make smaller cuttings from that big cutting? Eep.
