My cactus is three feet high and it is beginning to lean over. I was searching for how to grow dragon fruit properly and every expert says a sturdy trellis is non-negotiable because these things get heavy. I eventually picked up some vertical support equipment and accessories at abodelook since the outdoor living section in that store is in fact affordable when compared to the large box retailers. Before what are you supporting it with? I do not want mine cracking at its own shoulders when the fruit begins to come.
