Can a dragon fruit plant survive in saline water?

Dragon Fruit Plants 15 May 2020

Growing & harvesting dragon fruits in saline water and even salty soil has been experimented and done successfully in places around the world.

This is one farmer (Phuong) who has switched from farming brine shrimp into growing dragon fruits on his land:

Super duper cool harvest

The water condition around here is super salty. As the shrimp population decreased due to water contamination, Phuong was forced to find some other ways to make a living.

He experimented with different dragon fruit varieties from Binh Thuan (central Vietnam) & Tien Giang (south Vietnam). But they couldn't withstand the harsh condition there. Extremely lucky, he found the local variety (Camau dragon fruit). It works wonders on his land.

He uses mangrove trees (Avicennia marina), which are highly adapted to saline environments, as the dragon fruit posts. As the cactus grow, they develop air roots that latch on to the mangrove. Even with the tides falling & rising and the roots being completely soaked in water, the dragon fruits still survive.

Dragon fruits grown in salty environments are surprisingly sweet. There's no chemical fertilizer or boosters because there's no place to apply them. You get fresh, nature-grown fruits. If you're looking to grow dragon fruits in saline water, you can totally do it!

The incredible results of growing dragon fruits in salty soil


Dragon fruits grown in salty soil give a unique blend of sweet & saltiness. When a pioneer (Ra) played around with this idea of planting dragon fruits in his local area, fellow farmers were laughing at him. Now, they are all following this design to make 10x income for their families.

The place is in sea-bordered saline Tien Giang, which used to be a mass producer of wheat & rice. When doing it this way, the growers usually raise the dragon fruit posts high up & build good ditches for the seawater to escape out.

They utilize the organic materials available locally as fertilizers:

  • Straw or hay
  • Goat's dropping
  • Cow manure

Dried dragon fruit flowers & dragon fruit skin are also a great source for soil enrichment. The plants grow big, strong & disease-free. Nothing is more satisfying for the farmers on their returns. And for the consumers to taste truly good dragon fruits.
