Dupuis Saigon Mango Grow Guide

A descendant of the renowned Saigon Mango from Vietnam, Dupuis Saigon is a delectable Indochinese mango variety in its own right! While it didn’t inherit the ‘semi-dwarf’ genetics from its parent, this mango cultivar would be an excellent choice for those who appreciate the unique flavors of Indochinese mangos.

With that being said, this grow guide will cover everything that you need to know about Dupuis Saigon Mango:

Dupuis Saigon Mango Tree Growth Habit & Fruit Production

The Dupuis Saigon Mango is considered a large-sized mango tree.

Dupuis Saigon Mangos have a very vigorous & upright growth habit that produces a dense and open canopy. As a result, Dupuis Saigon can realistically be kept between 20 – 25 feet tall with annual pruning. With that being said, Dupuis Saigon would NOT do well long-term in containers and would NOT be considered a “condo” mango.

Due to its natural vigor, Dupuis Saigon can be challenging to manage for individuals with small yards or limited space. Despite its vigorous growth, Dupuis Saigon’s fruit production consistently ranges from average to good.

The mangos themselves are small to medium-sized fruits that typically weigh between 0.75 – 1.25 lbs. However, due to the presence of a large seed, the fruit does have a poor flesh-to-seed ratio.

Dupuis Saigon Mango Flavor Profile

Dupuis Saigon Mangos are considered a Classic Flavored Mango.

When fully ripe and mature, Dupuis Saigon Mangos will emit a delightful mango aroma. At this point, cutting into the fruit will reveal juicy, smooth, and soft light-yellow flesh with a somewhat firm and dense texture that will nevertheless melt in your mouth.

From a flavor perspective, Dupuis Saigon is bursting with a strong Indochinese flavor. The fruit is sweet with a mild acidity that hints at citrus. Additionally, there are melon undertones reminiscent of watermelon and cantaloupe, along with a subtle note of canistel that adds to the richness of the flavor.

There is just the right amount of resinous flavors to add additional complexity to the overall flavor, but not so overwhelming that it would turn off those who don’t prefer resinous mangos. Another interesting quirk that I have noticed is that the main flavor tends to linger pleasantly in the mouth.

When the fruit is less ripe, I’ve noticed that the classic ‘mango flavor’ is somewhat lacking. If I were blindfolded, I might not even recognize it as a mango (texture yes, taste not so much). However, as the fruit ripens and its acidity intensifies, the ‘mango flavor’ becomes much more pronounced.

It’s also important to note that the skin is quite bitter, so if you enjoy eating close to the skin, it might not be to your liking. Additionally, it’s best to not let Dupuis Saigon get too soft before consumption, as the fruit follows a similar decline pattern to other mango cultivars such as Carrie or Pina Colada.

Overall, Dupuis Saigon is an excellent fruit that appeals to a wide range of tastes.

Finally, it’s worth noting that Dupuis Saigon Mangos produce polyembryonic seeds, which means that planting a seed from a Dupuis Saigon Mango can yield another Dupuis Saigon Mango Tree.

Dupuis Saigon Mango Season (And When To Pick)

Dupuis Saigon Mangos are considered an early season mango (May – June). Dupuis Saigon also boasts a relatively brief season, during which the majority of the fruit on the tree is typically harvested within a span of 1 to 2 weeks.

The best time to pick Dupuis Saigon Mangos are when they are mature and beginning to ripen on the tree. From a color perspective, this is when the fruit is beginning to show signs of yellow color break. Dupuis Saigon Mango is perfectly ripe when the entire fruit’s smooth skin evenly transitions to whitish-yellow color.

Depending on the fruit’s level of sun exposure, it may also develop a pinkish-red blush on the top half of the fruit. However, it’s important to remember that a mango’s blush has nothing to do with the fruit’s ripeness. A rule of thumb to remember is that More Sun = More Blush, Less Sun = Less Blush.

Aside from color, here are some additional tips to knowing when Dupuis Saigon Mango is ready to pick:

  • Is the fruit beginning to soften ever so slightly?
  • Is the fruit beginning to emit a fruity aroma?
  • Is the fruit full-sized and has a plump appearance?
  • How does the stem look? Is it drying up near where it connects to the fruit?

Dupuis Saigon Mango Disease Resistance

Dupuis Saigon Mango is susceptible to Anthracnose. With that being said, Dupuis Saigon has shown resistance to Bacterial Black Spot.

Due to its susceptibility to humidity-related issues, it’s best to avoid planting Dupuis Saigon in highly humid areas like the Florida Interior. Instead, consider planting this tree only in coastal areas with good airflow.

Dupuis Saigon Mango History

Dupuis Saigon is a Saigon Seedling named after Dr. John Dupuis, who was a physician and surgeon in Miami-Dade County. Below is an excerpt on the history of Dupuis Saigon Mango from Walter Zill’s autobiography:

This seedling from Saigon was, according to John DuPuis, Jr., the favorite of his father. When I ate one it tickled my taste for more of the same. Early season, firm, but not fibrous, its shape and size is one of the easiest to hold and pack among mango fruit, and also beautifully colored yellow to pink when ripe. Very vigorous tree with moderate production of clean fruit.

Dupuis Saigon Mango Tree For Sale

Honestly, I’ve seen only a few Dupuis Saigon Mango Trees for sale in recent years. I believe this might be due to the fact that most consumers prefer mango trees with a less vigorously vertical growth habit, despite the excellent taste.

With that being said, if you are unable to find one at a local nursery, your next best option is checking out Tropical Acres Farms (not sponsored). They are the only legit place online (from my experience) that you are getting exactly what you are paying for. 

They have over 300 varieties of mangos available. You can either order budwood to graft yourself or submit a grafting request to have a grafted tree created for you. They do ship!
