They can be good mixed into a shake with other fruits that are sweet, like mango or banana. Otherwise, yes, they are very sour. Apparently there are some sweeter cultivars that can be eaten out of hand, but still sour. I like the smell but no a huge fan of the taste.

Sorry to offend Oscar, just got excited over the possible implications. I grew up in an agricultural area that does mostly canola and alfalfa. Its all automated now and there is no such thing as a small farm anymore. If this technology becomes viable and only suits mega farms, I imagine mega farms will be all that remains. If that pushes apple prices down, they'll just find more things to put apples into like they did with corn and canola.

Long post but once I started looking into it I found it fairly interesting. Apples are bigger business than I thought.

It would definitely be suited to a particular type of operation. If implemented it could do to the small orchard what modern thresher/combine units did to small grain farmers. If the same machine could be tooled to harvest several fruit crops (say mango, citrus, apples, avocado) then 1 mil would be cheap. Think of australia. Broad acre fruit farming is common here, generally on fairly flat terrain. Trellised apple orchards are more the rule than the exception. Our labor costs are high. 40%-60% of the crop is wastage because the local market can only handle so much b grade fruit, and the price for low grade fruit is too low to consider picking and shipping for processing. Last time I was in western Australia for the apple harvest there were piles of low grade fruit double overhead the size of tennis courts everywhere. If the automated picker could decrease fruit damage by getting them sorted and on trays without risking crush damage in bins, that would increase export quality volume right away. This is where the industry wants to go because the local market is saturated. I never realized how many apples the world grows but have a look at this. . I think there is volume for mass production of robots. Can that china figure be right?

Between mango, apple and citrus that's year round picking. If you run these units like the automated harvesting companies do on broad acre soy/rice/corn/grain.
1mil @ 6.5% over 10 years about 140k a year plus 5% equipment value for parts and repair and 5k insurance = 195k a year
Pick 250 days, 20 hrs a day. 105 days travel and maintenance = 50000 man hour equivalents.

That prices a machine hour at about 4 dollars. Write off interest costs in the business,  plus write offs on the depreciation schedule for plant and equipment. If you increase export quality fruit volume and cut wastage, crop volume and grade will increase. You could probably make your margin on the decreased wastage and increased export volume alone. That still leaves an 11 dollar gap assuming $15/hr for migrant labour. Early adopters would make some cash, then I imagine apple prices would crater leaving only the automated producers at a new lower floor price and normal business margins.

Long post but the ROI on equipment in my business is a fraction of that, but it still pays the bills. Automation is a threat in my line of work, so usually pretty interested in where it's at. Question is will it really be an improvement when all the unskilled jobs go overseas or to robots and the locals try the fill the gap with consumer credit and mortgage debt.

The thing about a robot is there is a large capital investment,  but low operating costs. Multiple picks wouldn't add much to cost like it would with human labor.

Do you have any in focus closeups? To my eye it looks to have a single alternate pattern with large buds, where the jaboticaba I am aware of tend to be opposing/small bud.

The df are on a concrete post and rail. The vertical posts are 6ft tall from ground level and the rails 8ft long. I was gifted a concrete mixer (one of those l've no place to store this so I'll keep it at your place but still come use it whenever I want kind of things) that has poured alot of cement in the 3 years since we moved in. They have not grown in all the way but this year we have so far gone through 2 bloom cycles with about 80 fruit harvested, just starting to get flowers from the 3rd cycle.



Tropical Fruit Discussion / First fruit: Rollinia
« on: March 16, 2017, 10:22:49 PM »
Just harvested my first home grown rollinia. Thought I would share some pics from seedling to fruit

21/02/2015- newly planted rollinia on right and soursop on left by fence

27/11/2015- espalier frame installed

22/12/2016- setting fruit, no hand pollenation

Picked the first one, still setting more fruits. Unfortunately the flavor was not the best, sweet but not alot of the lemony tang I have had in other rollinia.  On the plus side it set heavily without any hand pollenation,  few seeds and firmer flesh. Hopefully the taste improves with age.

And bonus, the neighboring soursop has set 4 fruits on its own.

Tropical Fruit Discussion / What is in season in Hawaii?

I'll be on the big island this week, wondering what's in season right now at the markets.

Been lucky here, maxed out at 35. Dry and windy though.

I don't think you would have trouble finding fruit anywhere that has a university in Australia.

On the gold coast and area
Miami organic market
Palm Beach / currumbin farmers market
Byron farmers market ( picone exotic orchards and jungle juice both sell here, dragonfruit,  sapote, soursop, rollinia jacks etc.)
Tropical fruit world ( subtropical and tropical fruit)

Farmers markets are very popular here, even the chains are not too terrible. Of course cairns will have the best tropical fruit,  but there is nowhere in australia where you won't find fresh seasonal, local produce suited to that climate.

Tropical Fruit Discussion / Re: Australian Fertilizers
« on: January 27, 2017, 02:46:17 AM »
I've seen both basaltic derived kraznostem and clay loam ferrosoil used to describe the dirt around here. At our place there is maybe a 10 cm organic band followed by 40 to 60cm of loose brown/red clay loam. After 60 to 80 cm you are into heavy red clay for several meters before hitting basalt.

Tropical Fruit Discussion / Australian Fertilizers
« on: January 26, 2017, 10:41:35 PM »
Looking for advice either from Aussie growers or anyone who wants to look at the analysis of a few of the fertilizers that are available at the local depot.

YaraMila Complex 25kg bag $33
N   12%
P   4.8%
K   15%
Ca   2.5%
Mg   1.6%
S   8%
B   0.015%
Fe   0.2%
Mn   0.02%
Zn   0.022%

Nitrophoska special 12-5-14-8 25Kg bag $30

Amgro prolific 12-5-14 or 10-2-20 (banana) 20kg bag $20

And for foliar TE they have
CMX TE Foliar 500g powder is $26
Cu 1.7% as EDTA
Fe 3.34% as EDTA
Mn 1.7% as EDTA
Zn 0.6% as EDTA
Boron 0.875%
Mo 0.023%

Right right now I'm just using chicken manure pellets, horse manure, blood an bone (whichever is available, cheapest, broken bags etc) mixed with rock crusher dust with some TE spray quarterly. I throw some potash around before the bloom cycle starts and a little more on bananas. Trees are all young and just coming into bearing. Still not entirely sure I want to start with chemical fertilizer, but looking at all the options. Might be time to get a little more scientific. I've noticed some deficiencies showing up in the black sapote(mg), citrus(zn or mn?) and jackfruit(mg). Really I've been fertilizing without any real "plan", and I figure like anything in life I'd be better off If i had one. Soil sampling is underway.

On the plus side a two foot tall one in a 12 inch pot will give you enough of them each year for the novelty to wear off. If you want seeds you csn have them for postage.

Tropical Fruit Discussion / Trellised Annona fruit thinning
« on: January 12, 2017, 04:14:54 AM »
Does anyone have advice on how much fruit load is ideal on trellised Annona?  I thin my trellised stonefruit to one a foot, which seems to give good fruit quality. I have a trellised rollinia with 4 wires, each 10 feet long, 20 inches between wires. I'm up to about 14 fruit set with lots of blooms still coming. Given the size of a rollinia fruit, when should I start thinning?

I planted a few seeds of this one, they took a little longer to germinate than papaya usually does but they grew fast. 6 feet tall and flowering at about a year from seed going in the ground. I've been told fruit quality is variable in seedlings.

yeah, I inherited about 200 yards of gal steel from a guy, so everything is the yard is made of gal steel. Its a sloped block so thats why the tatura has a  top and bottom bar. Also helps to support netting I guess, but would be way easier on a flat block a a ground anchor.

Poor light this morning, but here are a few

Soursop and rollina

Acerola, jambu behind


Just need more people to try it out and share thier results. My plantings are all 2.5 years or younger so a few more years before I can contribute much but so far
Guava- year round fruiting if you prune back fruiting laterals to the cordon when you pick fruit.
Mulberry- dwarf black and red shathoot seem to work well,  white shathoot too vigorous
Acerola- filled out the frame quickly, flowers like crazy, not setting yet
Wax jambu- seems overly vigorous,  no fruit yet
Rollinia- vigorous but 2 year old seedling has set fruit this year on its own. (90cm at planting, 2m tall now).
Soursop- grafted, flowering heavily at 2 years, will try to pollenate them next year
Canistel- grafted, flowering heavily at 2 years, easy to train to espalier
Black sapote- seems like it will work, is always flowering but hoping it won't be to vigorous once established.
Low chill stonefruit- multigrafted tree, a little vigorous,  sunraycer and nectarcot need to thin fruit, angel peach (ufo) seems to have poor fruit set, just added florida prince, sunset peach and sunset nectarine for the final cordons.
Carambola- probably the perfect espalier tree. I cut out the top and grafted giant sam, so it will be a sam and kari.

Jaboticaba- informal palmette would be the go, and I think would allow for easy fruit harvest and protection.  I plan on an informal palmette row for any new jabs since we have a crow problem.  Punch yourself in the crotch if you are considering anything formal with a jaboticaba.
Low chill apple- to hot here, never knows when to leaf out or flower. Underplanted some garcinias.

Time will tell with the rest.

When I was researching espalier and tatura systems there were a few papers that looked to determine what branch angle resulted in the heaviest fruiting. Too vertical and you got excessive of apical dominance, and too far below horizontal you lost vigor. Highest production was on branches allowed to grow as whips and then bent down to 15 degrees below parallel in apples. Similar results in stonefruit where growers had noticed that branches bent down by netting fruited heavier in cherry and peach orchards. There was not too much on tropicals, but what there was had similar types of results.

Thanks, my other Aureana produces leaves that are about twice as long, pointed, pendulous at first and and no curl at the margin. Now just the wait to see if the fruits are any different.

Tropical Fruit Discussion / Jaboticaba ID?
« on: November 20, 2016, 02:57:33 PM »
I received this jaboticaba as a white seedling from a forum member. The growth and leaves are quite different than a white given to me recently.  At first I thought it was a deficiency,  but I have grafted it on grimal and sabara and the growth remains the same. The odd thing is that the leaf margins curl under, especially in brighter light, and it is very lanky/droopy.

Very new growth

Starting to harden

Old growth

This is one of the grafted ones.

Tropical Fruit Discussion / Biggest Red Jaboticaba
« on: November 07, 2016, 06:15:46 PM »
Interested in seeing how big these have gotten and how old before they get there. I haven't seen any pics or video's of any larger than Adams large potted one. Are there any bigger ones around?
