Tropical Fruit Discussion / Re: Stressed Avocado tree
« on: June 23, 2019, 12:58:56 PM »
It looks like the soil in the pot settled quite a bit since the up-potting. I've had some pots do that and found that the media had decomposed down to mud at the bottom and sealed off drainage then the roots rotted. Like Spaugh said check roots with a strong helper. Avocado is very sensitive to root problems and pot culture is a tricky business it seems.

Aqua Yield/Tri-yield has a headquarters in Arcadia, FL which is central to the citrus growing area of Florida.

Barbados cherry is a quick grower. Pruning them back should help develop a stronger trunk and be more stable. They also respond well to pruning, usually by flushing and flowering.
Personally, instead of a standard tree form I prefer a low branching vase form.

It does depend on the tree but nature itself does quite a bit of pruning and topping. For example during hurricanes which are a typical feature of many tropical locations. Ice storms and forest fires do their part in temperate climates. Some of our fruiting trees are pioneers, short occupants with short lives, some live longer lives, and some live very long lives. So, depending on which tree you are talking about pruning should be done with that in mind and to get a reasonably easy harvest as mentioned.
Also by choosing dwarf varieties, dwarfing rootstocks, etc. less pruning can be done.

Today I had the chance to work on a lychee farm using a man-lift/ cherry picker. The basket was large enough for three of us and two 25 gallon bins for the fruit. One operator maneuvered the machine and two of us picked 200 lbs per hour, one large tree yielded nearly 500lbs fruit. They also use that machine to pick large mango and other trees. It has allowed the farm to let lychee grow very large and yield far more yet still be harvestable in a safe and efficient way so with the right tactics tree size can actually be a benefit.

Without pruning the tree will stay under the influence of apical dominance.
This is what is happening:

Don't be afraid the Valencia Pride won't become a large yard tree. That will happen whether you like it or not, given enough time.
The influence of apical dominance and the ultimate shape of that tree is within your will should you choose to exert it.

You also must break all that cement at least 3ft wide when ready, hopefully its not too thick of a rock layer and you hit dirt down under again
I imagine electric jackhammers are available in Singapore. If roots get below the concrete there may be little competition down there.

Are you familiar with their use of herbicides to manage weed growth within the rows?
They probably do but right now I don't see any signs of it. The grove has been there quite a few years and once the trees grow light level is low, but I do see some annual grasses right now. They use a flail type mower to grind the prunings in between the trees and it does produce mulch. The windbreak around the grove probably does keep out windblown seeds.

Another update 2 months after heavy pruning the trees have flushed new growth, flowers, and some small fruit.

It has only been 3-1/2 months but the trees shown in the original video have really grown out, they are blooming and have set a few fruit.
I'll be needing to bend the new growth soon. Some have cherry tomato growing up in the tree.
Here are a few pics:

Seedlings start out with nutrition supply from what was stored in the seed. Hard to see from your photo but the built-in reserves of the seed will eventually run out and you will need to supply it.

Over time that strong turf will be competing for water and fertility right at the trunk of the tree. I've heard many trees get damaged by trimming grass, especially by weed eaters. My one year old trees have fine feeder roots running outwards 3 feet from the trunk. As I recall some places in the Miami area have limestone close to the surface. Those are things to consider.

Right at ground level your tree has a curve which could be the graft of a t-bud grafted tree. If you dig a little deeper you may see the graft just below soil surface. If so, the tree was planted a little deep. In this old forum thread you can see what a t-bud grafted tree looks like at the graft.

Tropical Fruit Discussion / Re: Dragonfruit un Russia

Your Russian Dragon Fruit looks to be growing about the same as mine was a few months after planting. I have tried to see it through your eyes imagining trying to grow green peas (Pisum sativum) during our Florida summer with temperature of 35C and near 100% humidity. I would have to seal up my shade house, install air conditioning to bring down the temperature and humidity, and make sure none of that ever failed all summer long. Even one day of failure would be the end of my pea-growing. Good luck to you.

Hard to believe you folks who wasted money and years on this guy didn't run him out of town yet.

Hi Guys!
I have searched the forum and not found the dosage for Osmocote Plus for potted trees.
The package says 1 scoop (3 tbs) per 2 GAL pot, OR for 4 sq ft.
My 25 gallon pots are about 2x2 ft.
So, do I give them 12 scoops (calculated for pot size), or 1 scoop (calculated for sg ft), or something in between?

This is a HUGE difference!!
I called Osmocote, and they said to give each pot 12 1/2 scoops.
But all are light feeders, I believe (several annonas, cinnamon, cacao, lychee, jabo, etc...), and I don't want to kill them. Unlike soluble fertilizer, I can't just flush this stuff out.

Anyway, I gave the pots 4 scoops each, for now, figuring I can add more, but can't take it away.

So, an accurate dosage, that has worked well for quite a while for someone, for potted trees, would be a BIG help!!!!


This is what Osmocote says about their product:

I use Nutricote.
The Nutricote I have had no problem at all planting sensitive seeds right on top of the granules at any rate.
Put a handful of Osmocote in a pot and plant some beans on top of it.
This will give you a visual test of how good your slow release fertilizer really is. If a bare seed has no problem a hardy tree seedling shouldn't either.
They release over 180 days and I typically add mine to potting soil when potting up, and every six months throw a handful on top of a 3 gallon.

Even though I grow in the ground with plenty of water and fertility sometimes I have gotten flat branches but then they change back to normal 3 sided.

I think this may be part of the spectrum of disorders called Internal Breakdown specifically stem end but including "soft nose" and "jelly seed". You can google these terms and find out more. This is typical of what you may find;

Tropical Fruit Discussion / Re: Fruit thieves
« on: June 13, 2019, 07:48:29 AM »
I'm pretty sensitive to theft having been a victim many times of household burglary and fruit/garden theft in another country. The result of these continued and usually unsolved violations has left me with a strong feeling against it and I would probably lose my temper if I saw it happen again. I once walked around a tree to confront a teenager starting to fill a bag and picked up a long pole and began beating him till he left the property. The next time I had a machete in hand and did not strike but the chase continued while someone called the police and the thief was arrested. Another time it was a car chase on a thief with bicycle loaded down with 50 lbs all the way to town and police would not react. The bag was found in a dumpster and I negotiated with the thief's family who was known to me.
This happened 30 years ago but the memory is still strong. I hope that I can act responsibly now that I am older but no guarantees.
Thieves probably don't realize what they are getting themselves into if they move against me.

The Kasturi fruit have a very strong smell that annoys some people. I've heard it described as petroleum oil or diesel. Being a mechanic most of my life it doesn't bother me.
I think you are confused with kuini, that is the one with the strong smell , that''s why the name Mangifera odorata. Kasturi does not have a strong smell.
No, not confused and definitely Kasturi and others here agree with me. To me it is fine I like strong flavors & eat them since it reminds me of old times but some people (my wife) are more picky.

When the fruit ripens take a ripe one and a branch with leaves to Fruitscapes nursery on Pine Island and ask one of the owners. They have been able to identify many varieties for me based on those and the season of ripeness.

Yes, I've tasted diesel many more times than I care to remember, even have gotten a full bath of it before(not on purpose). One time on the ship where I was chief engineer the delivery had hundreds of gallons of water and I suspected it was sea water from a leak on the delivery vessel and forced myself to taste the decanted water- it was salt.

Nice looking fruit wha5 does it taste like ?

Not any strong flavor, maybe a little buttery without being oily. This is in the cucurbitacea family genus Momordica and while not bitter at all you could maybe compare it to the red seed covers of a ripe bitter melon momordica charantia when the bottom opens and seeds fall out.

In shadier conditions trees which evolved to be in full sun will tend to grow taller and thinner too, reaching for light. If you have warm  enough conditions or even under other trees Monstera deliciosa prefers shade.

Maybe he had no female flowers in perfect condition for pollination or he removed the flower petals before touching the stigma. He may have done this so you could see better. The female flowers even before pollination have an ovary which looks like a miniature Gac fruit much the same way a cucumber can be seen under the female flower.
