Captlaw starts with ... Two of my dragon fruit have started to rot from the ground up. The white one has almost reached the top of the first segment, about 300mm, the flesh has gone a yellow/brown and is soft. Has anyone experienced this and is there a treatment. The red one has just started to go soft from ground up 100mm. All the upper stems are fine except for a little sunburn from the intense heat the past few weeks. | About the Author Captlaw Malanda 11th January 2014 10:57am #UserID: 9296 Posts: 8 View All Captlaw's Edible Fruit Trees |
phil@tyalgum says... I found the same thing happened with my red dragon fruit, it is now no longer connected directly with the ground but still continues to grow happily onwards and upwards. The aerial roots seem to be more extensive and have wrapped themselves around the support, I imagine they get most of their water and nutrients in this manner. | About the Author TyalgumPhil Murwillumbah 11th January 2014 1:02pm #UserID: 960 Posts: 1377 View All TyalgumPhil's Edible Fruit Trees |

sternus1 says... Dragon fruit can be watered to death if the soil isn't free draining. Clay is especially bad. That said, they can be cooked to death too, they are nothing like an opuntia, and if treated as such will die very quickly. I would check for parasites. I had very similar rotting to this as a result of some sort of grey slug/worm like creatures which seem to have entered the fleshy outer via the ground. Cactoblastus cactorum will go for dragon fruit, too. s | About the Author sternus1 Australia 13th January 2014 12:29am #UserID: 8314 Posts: 1318 View All sternus1's Edible Fruit Trees |

Fruitylicious1 says... Hi Big H Yes you are right. Excessive heat specially during summer will cause dragon fruit stems to be sunburnt hence causing discoloration starting with yellowing and progressing to brownish tint. What professional growers do is to install a 50% shade cloth to protect the DF during forcasted high temp days like high 30's and above. You can remove the cover when the temp goes back to normal. If your DF is in a pot you can shelter it under a tree inside a veranda or pergola. Overwatering whether by nature (rain) or human can also cause rotting of DF's. They hate waterlogged soil like clay. Plant it on a mound, raised bed or in a big pot to improve drainage. Since you have not uploaded a picture of the infected pitaya it's very hard to ascertain which one of the various pathogens has infected your DF.
