I've tried this on 50-60 cuttings and it hasn't worked. I tried the method shown here and it hasn't grown roots. I took cuttings off of different plants, changed the soil mix, still nothing.
Hey James, sorry it took so long to reply. I have about 75%+ success. It doesn't matter how hot it is the key to get them to root successfully is to water consistently everyday because when you miss a couple of waterings is when they will start dying.
Good video but never told us how long to leave in the sand before transferring to ground/pot and what to do once that stage is done eg how often to water what type of soil?
