I watched your video in its entirety. I saw that the dragon fruit seedlings are still small. I hope you get good results if you take good care. There is a lot of demand in the dragon fruit market. And it contains lots of vitamins. I really like the size and color of this fruit.
But I think it is very difficult to take care of this Dagan fruit tree. Fertilizer water is to be applied regularly. And to balance it, you have to stand upright with a bash or a support next to a tree. These dagon fruits come to the tree after many days. Thanks..
