Super Julie Mango is essentially a Julie Mango with a few settings cranked up:

  • Increased Disease Resistance
  • Increased Growth Vigor
  • Increased Fruit Productivity
  • Increased Beauty

If you love mangos in the Julie family (i.e., Carrie, Ugly Betty, Angie, Juliette, Graham, etc.) then I guarantee that after trying Super Julie, you’ll be be adding Super Julie Mango to your list as well 🙂

Note: A lot of my descriptions in this grow guide will be comparing Super Julie to Julie.

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

Super Julie Mango Tree Growth Habit & Fruit Production

The Super Julie Mango is considered a medium to large-sized mango tree.

Super Julie Mango Trees have a very vigorous & spreading growth habit that produces a dense canopy. As a result, Super Julie can realistically be kept between 10 – 20 feet tall with annual pruning. With that being said, Super Julie would not do well long-term in containers and would not be considered a “condo” mango.

Interestingly enough, Super Julie’s growth habit appears to be the exact opposite of Julie’s, which is widely considered a true dwarf mango cultivar.

Super Julie’s fruit production consistently ranges from good to heavy. Additionally, Super Julie not only has much higher levels of production compared to Julie but also yields larger and plumper fruit in comparison to Julie.

The mangos themselves are medium-sized fruits that typically weigh between 1 – 1.5 lbs.

Super Julie Mango Flavor Profile

Super Julie Mangos are considered an Indian Flavored Mango.

When it comes to Super Julie’s aroma, I have never been able to detect the aromatic and strong classic mango scent that I commonly associate with Julie. It’s a pleasant-smelling mango, but it’s just not as intense as Julie’s.

Super Julie’s orange flesh is fiberless, juicy, and boasts a velvety texture that simply melts in your mouth. Notably, Super Julie is definitely juicier than Julie. Here’s a Pro Tip: Super Julie’s peak flavors can be enjoyed when the flesh is orange vs a deep orange (they have a tendency to over-ripen really fast).

In terms of flavor, Super Julie offers a distinctive West Indian/Caribbean taste profile. The fruit is a delightful fusion of sweetness and an intense “Caribbean sweet spice” flavor, accompanied by subtle acidic and resinous undertones that are present in every bite. Moreover, you’ll also detect a “zing” that is very reminiscent of Carrie and Ugly Betty.

What’s intriguing is that while Super Julie does offer some flavor complexity, it’s notably less complex than Julie. I have never personally tasted a Super Julie with the same intense tangy notes of citrus, pineapple, and coconut that I typically expect to find in Julie. More specifically, the fruit’s flavor seems to be subtly mellowed down.

Another interesting little tidbit is that an underripe Julie bears a striking resemblance in taste to a ripe Super Julie.

Overall, Super Julie is a good choice for mango enthusiasts who appreciate varieties like Carrie, Ugly Betty, and Julie. However, if I had to decide between planting a Julie or a Super Julie, I honestly would lean more towards Julie. That is because I am a fan of the heightened flavor intensity and sweetness associated with Julie.

Additionally, I live closer to the coast where there is less disease pressure (more on that later).

Finally, it’s worth noting that Super Julie Mangos produce monoembryonic seeds, which means that planting a seed from a Super Julie Mango won’t yield another Super Julie Mango Tree.

Super Julie Mango Season (And When To Pick)

Super Julie Mangos are considered a mid-season mango (June – July).

It’s crucial to harvest Super Julie Mango at the right time since it quickly goes from ripe to overripe. Overripe fruits will often have off-flavors, diminishing their true flavor potential. Similarly, Super Julie can acquire a chalky taste if picked too early. Once harvested, these fruits should be enjoyed within a few days.

Much like Julie Mango, Super Julie reaches its peak flavors when allowed to tree-ripen and appears ready to fall from the tree. However, Super Julie’s growth habit, which leads to more fruit higher in the canopy, increases the likelihood of damage or bruising due to fruit drop.

With that being said, the best time to pick Super Julie 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 orangish-yellow color break. Super Julie is perfectly ripe when the majority of the fruit transitions to a orangish-yellow color.

Super Julie also commonly develops a beautiful red ruby color. However, it’s important to remember that the red blush has nothing to do with the fruit’s ripeness. In fact, the amount of red blush that a fruit will have is dependent on the fruit’s exposure to the sun. More Sun = More Red, Less Sun = Less Red.

Aside from color, here are some additional tips aside to knowing when Super Julie Mango is ready to pick:

  • Has the fruit fattened up?
  • Are there lenticels (little dots) present on the fruit?
  • Is the fruit beginning to soften?
  • How does the stem look? It’s it drying up near where it connects to the fruit?
  • Are there beads of sap present on the fruit?
  • Is the fruit’s skin beginning to stretch?

Finally, it’s perfectly normal for Super Julie Mango to drip sap when picked 🙂

Super Julie Mango Disease Resistance

The main selling point of Super Julie Mango is its enhanced disease resistance when compared to Julie Mango. In particular, Super Julie is resistant to Anthracnose and Powdery Mildew. With that being said, Super Julie is susceptible to Bacterial Black Spot.

Consequently, while Julie Mango typically requires planting in a “high and dry area” or an area with regular coastal breezes, Super Julie can thrive inland thanks to its heightened resistance to Anthracnose.

Super Julie Mango History

The Super Julie Mango was initially propagated in Boynton Beach, Florida by Gary Zill.

Throughout the years, this mango cultivar has been known by various names, including J-12 (its original planting name) and Fairchild Ruby (distinct from Fairchild Mango). Therefore, if you come across any references to either of these names, they are all referring to Super Julie 🙂

Super Julie is a seedling of Julie Mango. It’s pollinating parent is unknown.

Super Julie is also a sibling to Dwarf Hawaiian, Little Gem, Juliette, Sophie Fry & Graham. Super Julie is also an aunt to Carrie, great aunt to Ugly Betty, and great aunt-in-law to Angie 🙂

Super Julie Mango Tree For Sale

Super Julie Mango Trees are very common in the Florida nursery trade. Over the years, I have seen more and more nurseries selling Super Julie vs Julie. This is likely due to Super Julie’s increased disease resistance.

With that being said, there is still a large demand for Julie Mango because it’s not a 1:1 taste between the two mangos. Furthermore, Julie Mango is still one of the most popular mangos enjoyed in the Caribbean.

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!
