Okrung Mango Grow Guide

If you want a super-sweet mango that flies under the radar (at least for humans โ€“ squirrels might disagree), you should consider planting an Okrung Mango Tree ๐Ÿ˜Š

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

Table of Contents

Okrung Mango Tree Growth Habit & Fruit Production

The Okrung Mango is considered a medium-sized mango tree.

Okrung Mangos have a moderately vigorous & upright growth habit that produces a dense canopy. As a result, Okrung can realistically be kept between 10 โ€“ 15 feet tall with annual pruning. Due to the treeโ€™s natural vigor & upright limbs, Okrung would not do well long-term in containers and would not be considered a โ€œcondoโ€ mango.

Young Okrung Mango Trees can experience issues with sparse fruit production due to infrequent flowering. However, as the tree continues to mature, Okrung’s fruit production will consistently range from fair to average.

The mangos themselves are small-sized fruits, typically weighing between 0.5 โ€“ 0.75 lbs, and are often found in small clusters throughout the tree. However, I have observed that the fruit’s final size largely depends on the number of fruits hanging on individual clusters.

Furthermore, due to Okrung’s wide and thin seed, the fruit typically exhibits a less favorable flesh-to-seed ratio.

Okrung Mango Flavor Profile

Okrung Mangos are considered a Thai Flavored Mango.

When perfectly ripe and mature, Okrung’s skin can vary from vibrant green to a delicate yellowish-green, sometimes adorned with a hint of red blush (depending on where it’s grown). Moreover, Okrung can be savored even before reaching full maturity, a common practice in Thailand.

When it’s perfectly ripe and mature, cutting into the fruit reveals a juicy, light yellow flesh with just a touch of fiber, which is in no way objectionable. In terms of flavor, Okrung is a delightful surprise, delivering a remarkable sweetness that reminds me of chewing on sugarcane or enjoying an exceptionally ripe banana. The ripe Okrungs that I have had the pleasure of sampling have stood as some of the sweetest dessert mangos that I’ve ever tried.

Beyond its sweetness, Okrung boasts an Indochinese flavor with subtle resinous notes that impart a gentle hint of spiciness. Although there is a touch of acidity, it doesn’t contribute much complexity to the flavor profile. Compared to other mangos that I’ve sampled, Okrung reminds me of a highly concentrated Nam Doc Mai, offering a flavor akin to pure sugar water infused with a delightful fruity essence.

Bonus Tip: Okrung is one of my favorite mangos to dehydrate because they literally turn into candy ๐Ÿ˜†

Finally, itโ€™s worth noting that Okrung Mangos produce polyembryonic seeds, which means that planting a seed from an Okrung Mango can yield another Okrung Mango Tree.

Okrung Mango Season (And When To Pick)

Okrung Mangos are considered a mid-season mango (June โ€“ July).

The ideal time to harvest Okrung depends on your intended use for the fruit. If you’re aiming to enjoy them while they’re still green, they can be picked when they reach a mature green stage.

On the other hand, if you prefer the fruit to have the “sugar cane” sweetness, the best time to pick Okrung 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. Okrung is perfectly ripe when the majority of the fruit transitions to a greenish-yellow to dullish-yellow color.

Another key ripening characteristic to watch for when picking Okrung Mangos is the appearance of a peach-like crease or seam running down the fruit’s side. In addition to this seam forming, I have also noticed that the top portion of this seam will gradually turn a whitish-yellow when the fruit is ripening up.

Additionally, here are some additional tips to knowing when Okrung Mango is ready to pick:

  • Is the fruit beginning to soften ever so slightly?
    • When in doubt… this is a great indicator!
  • 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?

Whether you plan to enjoy them while they’re still green or fully ripe, Okrung’s predominantly green appearance, even when ripe, and compact size make it a mango that doesn’t tend to attract too much attention from pedestrians ๐Ÿ˜‰

Lastly, thanks to its mild fiber content and manageable size, there’s no need to be concerned about the fruit bruising if it drops from the tree.

Okrung Mango Disease Resistance

Okrung Mango demonstrates impressive resistance to Anthracnose; nevertheless, it is susceptible to Mango Bacterial Black Spot.

Okrung Mango History

Okrung Mango was introduced from Thailand to Florida in 1973.

I’ve also had the pleasure of confirming, through my local Thai restaurant, that Okrung is traditionally served with sticky rice ๐Ÿ˜‹

Below is an excerpt on the history of Okrung Mango from Walter Zillโ€™s autobiography:

A variety from Thailand. I consider it among the sweetest mango fruit. A mango grower of long experience expressed his observation that those varieties that remain green in color until ripe develop the sweetest flavor. Maybe he is right. Does sunlight on green mango fruit generate more potential sugar than would be the case if the fruit had a red color?

Okrung is very early. The small ripe fruit drop easily when near ready to eat, and are damaged very little because of enough fibers to hold their nearly white pulp intact. Leather made from unadulterated puree of this variety became filled with sugar crystals within a few months of being made.

Finding an Okrung Mango Tree for sale can range from uncommon to rare. Despite Okrung’s extraordinary sweetness, when it comes to Thai mango cultivars, varieties like Nam Doc Mai or Maha Chanok are often the more popular go-to choices for most people.

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