Grow red flesh dragon fruit at home by choosing a medium-sized plastic pot, making sure it has enough room for strong roots. Prepare a nutrient-rich soil mixture, mixed with sand and organic fertilizer. Place the rooted red dragon fruit branches in the pot, then cover them with a thin layer of soil. Regularly check and water the pot every day, but keep the humidity level moderate, avoid over-watering as it will damage the roots. Prune off unnecessary branches, so that the tree's nutrition focuses on developing bright red dragon fruit.
