Growing & harvesting dragon fruits in saline water and even salty soil has been experimented and implemented successfully in places around the world.
This is one farmer (Mr. Phuong) who has switched from farming brine shrimp to growing dragon fruits on his land:
Ever tried harvesting dragon fruits on a kayak?
We're getting there:
The water condition around here is super salty. It's around 50‰ or 50 parts of salt per 1000 parts of seawater. As the shrimp population decreased due to water contamination (with increased concentration of toxic gases like H2S, NO2), Phuong was forced to find some other ways to make a living.
And by a touch of lady serendipity:
With a stroke of luck
He experimented with different dragon fruit varieties from Binh Thuan (central Vietnam) & Tien Giang (south Vietnam). But they could not withstand the harsh condition there. And with a stroke of good luck by Lady Serendipity, he found the local variety (Camau dragon fruit). It has worked wonders on his land.
But in saline waters like these:
What are the dragon fruit posts made of?
The dragon fruit posts that we have seen earlier are actually mangrove trees (Avicennia marina). These are highly adapted to saline environments & can provide the nutrients for the dragon fruit vines. 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 fruit plants will still survive.
How is the taste of the fruits?
Surprisingly, dragon fruits grown in salty environments are pleasantly sweet. There is no chemical fertilizer or boosters because there's practically no place to apply them. If we pour the fertilizer in, it will get carried away with the water before the plants have time to take them up.
The prices for these saline-water-grown dragon fruits, according to the growers, are triple that of the normal ones. Growing dragon fruits this way, you get fresh, nature-grown sweet treats. If you're looking to grow dragon fruits in saline water, it is totally possible.

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 (Mr. Ra) played around with this idea of planting dragon fruits in his local area, fellow farmers laughed and questioned his decision. 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. As production became stagnant due to the high levels of salt in the soil, the locals needed to switch to some other ways of farming to make their living.
And they went with the dragon fruits, which seemed like an insane choice at the time for this area. When growing dragon fruit this way, the growers usually raise the dragon fruit posts high up & build good ditches for the seawater to escape out.
They utilize local organic materials as fertilizers:
- Straw or hay
- Goat manure
- Cow manure
Dried dragon fruit flowers & dragon fruit skin are also a great source for soil enrichment. The results are nothing short of amazing. People's hard work have paid off and even in the very first year of their planting. The dragons 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.
