Mango trees seem pretty good about dropping fruit if they can't handle it without any help. There's a good chance the tree will drop all on its own.

By the way, sugar cane is commercially replanted every three or four years.  On the other years, cane regrows from the same roots.  The biggest crop is in the second year.

Sugar cane sugar is highest in the oldest cane.  Immature cane has a lower sugar content.  Consider leaving it until next summer if only 3 foot high.

Sugar content is also generally highest when the cane is under heat and/or water stress.  Give it plenty of sun.   You can cut some cane and leave others.

My calamondins are extremely bitter.  Good to mix in a jam or marmalade, but that's about it.

Amazing, yes.  The largest varieties here in Fiji grow to almost to almost their full diameter while less than a meter tall.  Then it shoots up with all the pent up energy.   It's almost like a telescoping antennae cord on an old radio. 

One tree will probably grow a lot faster than the other, so pruning will be necessary to allow the weaker one to capture sunlight.  They might not be the most pretty-shaped trees in the yard.

Avocado is a shallow-rooted tree, despite it's initial taproot.  Mango puts out more deeper roots.  I wouldn't put any soil barrier between them.

Rambutan are also sensitive to wind.  They show brown leafy edges in windy conditions.

I'm sorry about the drought in your neck of the woods. I wonder if severe pruning would help reduce your plants need for water, at least until the rain shows up again?


I started pruning the citrus today.  I had been delaying because I thought we'd get some rain.  Not severe pruning, but getting the low branches and the highest branches off.  Thanks for suggesting. 

Very simplistic. Scientific investigation requires strict control of variables and reproducibility of results to be valid.

Strict control of variables is needed if we want to measure the best mango genetics, but not if we want to measure the sweetest mango.

When we give control of the variables to the people competing for the sweetest mango, we are measuring not only the genetic material, but also the skill in managing the growing environment.   Pumpkin growing is a good example, were competitors plant excellent genetic material, but also have their own watering and fertilizing methods.

There is no possible way for competitors across the world, country, state or even county to equalize all the growing variables.

It's my understanding that Guinness confirms world records, not U.S. records.  If they have no other 'sweetest mango' on record, whatever submitted should win until someone else beats it, assuming their regulations were followed. 

The growing does not need to be under identical conditions.  It's similar to a 'biggest pumpkin' contest.

Nice idea to attempt an official world record. 

I suggest contacting Guinness before going much further, to understand their evidence documentation requirements, need for an adjudicator, and other criteria that might need to be met so they can do their confirmation research.

nice pics,, besides the ones you mentioned a few others that I've seen do well in drought conditions are jujube , surinam cherry and pomegranate

My Surinam Cherry is doing well.  Pomegranate not so well - lost most of their leaves.  My climate is probably too tropical for Jujube.

You don't have any dragon fruit? Would consider planting Cereus sp. and Opuntia sp. (have to check on individual selections tolerance to moisture especially for fruit set). They will always produce drought or no drought. The pictures look more like Southern, CA then Fuji,.

My Dragon Fruit is doing well.  I would like to get some Prickly Pear, but I doubt I can find it in Fiji.  Can it be grown from the supermarket fruit?

I'm hoping most of my trees will recover.  The last serious drought here was in 1997, with a moderate drought in 2007.

This article linked below introduces a book titled The Ghosts of Evolution: Nonsensical Fruit, Missing Partners, and Other Ecological Anachronisms.  The book seems interesting, has good reviews, and is now on my Amazon wish list.  Has anyone read it?

"avocados coevolved with ground sloths and were originally eaten by gomphothere — elephant-like creatures that lived during the Miocene and Pliocene, between 12 million and 1.6 million years ago, who happily reaped the fruit with their hefty trunks, crunched them with their massive teeth, and passed the seeds comfortably through their oversized digestive tract.

"Avocado’s strategy for propagation made a great deal of sense throughout the long life of its lineage — until the present moment. Even after thirteen thousand years, avocado is clueless that the great mammals are gone. For the avocado, gomphothere and ground sloths are still real possibilities. Pulp thieves like us reap the benefits. Homo Sapiens will continue to mold the traits of the few species of genus Persea it prefers. Ultimately, however, wild breeds will devolve less grandiose fruits, or else follow their animal partners into extinction."

Tropical Fruit Discussion / Fiji Drought
« on: September 28, 2014, 01:10:03 AM »
It's been nearly five full months since the western and northern parts of Fiji's main islands received significant rain.  Some water wells and bore holes have dried up, and government is transporting water by barge and truck to some affected areas.   Livestock farmers are culling herds due to lack of forage, and moving their stock to neighboring areas to find grass.  Vegetable farmers can't plant and are harvesting some crops prematurely.  Wild fires are increasingly problematic despite a fire ban.  Hydro-power electric plants are expected to start running short of water within a month.

My farm's bore hole is still providing enough water for my household needs, but not enough to keep all 15 acres properly watered, or to give to more than one or two neighbors. 

I'm learning a lot about which young tree species are most drought resistant.  Citrus tolerance is disappointing.  I'm focused on keeping the most exotic fruit trees alive and to preserve maximum fruit diversity. Mature trees are doing much better than the younger ones.   A few mostly sad photos from my farm:

Soursop is trying to hang onto a few fruit while shedding many leaves.  Young coconut and sugar cane are suffering

Papaya, Banana/Plaintain and Breadfruit have shed most leaves

Some trees, such as this little Jackfruit and Mulberry, are still trying to fruit:

Citrus fares poorly on most of my soils despite hardy rough lemon rootstock.  Here's one of the worst:

Black Sapote, Star Apple, Jamaican Cherry, Ice Cream Bean, Abiu, Langsat. and avocado are doing okay with a little supplemental watering.

Among the most drought resistant on my soil are Mango, Sapodilla, Cinnamon, Macadamia, Cashew and Sandalwood (Yasi)

Of course I'm watering the shadehouse but I need rain before I can collect scion wood for grafting, and to plant out.

Chance of rain tomorrow. . . .

What ratio of mango to soursop do you recommend?

I think it is asking too much to expect a nursery to cover a disease issue two years after the purchase.

That would be understandable if the disease wasn't one that was shipped with the tree as is likely the case with the Southern Blush. Nurseries need to be held responsible for spreading malformation because there should be an implied warranty that you're getting a healthy tree when you buy it.

Agreed, but the buyer should bear some burden to show that the disease was in fact present when the plant was purchased, and not introduced later.  Perhaps one's own pruning equipment spread the disease, or insects.

I think it is asking too much to expect a nursery to cover a disease issue two years after the purchase.

Ouch!    Get strong.

Tropical Fruit Discussion / Re: Ice Cream Bean
« on: September 11, 2014, 12:21:31 AM »
I planted a few Ice Cream Bean from seed in May of last year (beginning of the tropical dry season here).  Two have their first flowers now.  So, yes, one year from seed!

My trees are approximately 3-4 meters tall now (10-14 foot). 

The '3 year old trees' in the original post should be fruiting by now in Hawaii.

Although my Ice Cream Bean have been blooming for several months, it hasn't set any fruit.  Maybe they're just practicing for next year.  I've had several species of fruit trees fail to set fruit in their first year of flowering. 

Or maybe it's the drought.

A great project!  Your hope your trees will thank you for the top soil with abundant fruit.

Will you do anything to minimize soil erosion until some grass grows in?

Banana, papaya, soursop, mulberries.  Great in smoothies.

Tropical Fruit Discussion / Re: papaya issue
« on: September 03, 2014, 03:15:39 PM »
My papaya get these too.  Nothing to worry about.  It does not ruin the fruit.  My guess is that it's a mild wound to the fruit's skin, and the fruit scabs over to protect further damage.  I suggest not picking them off.

Tropical Fruit Discussion / Re: Best Way to Consume Carambola
« on: September 02, 2014, 07:56:56 PM »
My carambola are a bit tart, and find they are great mixed with papaya:

  Papaya, in 25 mm (1") chunks  - 4 parts
  Carombola, in 10mm (3/8") pieces - 1 part

It adds a complexity to the flavor than papaya, without adding as much acid as lemon or lime juice.  Yum!

Tropical Fruit Discussion / Re: Slow-growing Marang (Terap)
« on: August 31, 2014, 01:12:38 AM »
Yes, hair on the leaves.

I'm planning to dig up my worst one and return it to the shadehouse for some intensive care.  And then what....?

Tropical Fruit Discussion / Slow-growing Marang (Terap)
« on: August 31, 2014, 12:20:53 AM »
I am concerned that something is causing my few seedling Marang to grow slower than their potential.  The grew fast in the shadehouse while they had energy from the seeds in plastic bags, but when planted out they've hardly put out any leaves. 

They are in well-draining loam soil, 40% shade (under cassava that will be cut out when the Marang grows a bit), and I water it weekly.  A bit windy, but not extreme enough to bother Jackfruit or Breadfruit.  Soil  is pH near 6.5.  I have not fertilized them yet.   Here's a sad picture of one of my Marang:

Since my Jackfruit and Breadfruit thrive in a similar environment on my farm, I can only speculate that Marang has somewhat different environmental needs.  Wind, maybe?   Any ideas?
