Cheers to a productive year!

Thanks for hosting again Brad! always a good time. And to Simon. I second the comment on the Inca Red. Great acid/sweet balance. Almost lemony.

The golfball sized yellow strawberry guavas were also well received. And the bananas.

Mine have always been bland. Very easy to peel though.

Had my first Xie Shan this week from grafts last year. Definitely a winner Millet.

Looks like two or female to me. The other lids eventually fell off on my seeds.

All i'm aware of is the eye count method and then flowering. I don't know of any in between indication.

I have 3 in my front yard also from Stuart many years ago. Biggest is 2.5" diameter and just passing my eaves. Female by eye count, but hasn't flowered yet.

Is there a way to encourage particular buds to push along a branch/trunk (other than lopping off everything above it)? I've read about forcing buds on citrus trees by notching above the bud you want to push, is this effective in mangoes? If it's not, is there another way? I have a few small trees that have trunks that split to V (2 branches), I'd like to have 3 or 4 main branches instead of just 2.

Girdling branches worked for me.
I've done this around a dozen times.

I prefer to do this a few months before top working, it gives the new grafts some shade

I can't make anything out. How do girdle?

Can you just pop off the leaves @ that bud?

My mulberry tree leafs out at strange times and loses leaves slower on the side exposed to the streetlight but flowering/fruiting seems unchanged. Avocado, fig, white sapote, nectarine, loquat seem entirely unaffected. There's a couple others i'm unsure about.

Some genetic work has been done to determine the cold tolerance of Cherimoya.

It appears that 'Chaffey' may be among the most cold tolerant of varieties.

Thanks Oolie!

Seeds germinated. Poly embryonic.  How does one breed poly mangoes?  Pollinate a mono with a poly?

See you then!

Maybe Iíll bring some retaining wall blocks if my back is up for it.

Shane which dates are you going to be traveling?

Camping the 25-27th. Might also be doing something the couple days before or after. Thanksgiving :)

Will definitely be there if I'm in town. Probably have jujube, surinam cherry and yellow strawberry cherry. Rat cleaned out my longan...

Many more hours of research later...I'm seeing a lot of complaints about the constant pressure pumps (SQE). Mainly that when they work, they work great, but when they fail they fail very badly.

Couple people are promoting Cycle Stop Valves (CSV) as a better option compared to either the constant pressure pump or traditional large tank setup. As far as i can tell it simply regulates the pressure output of a constantly running pump. With a small tank and switch set to e.g. 40-60psi, when the tank drains down to 40psi the pump turns on and assuming the CSV then is set at say 50psi, the pump just keeps going until your turn your water off. No cycling.

Anyone have any experience with this setup? Seems the most trouble free option of the three.


When does yours flower (what month)? I have one in the ground 6 years or so and this year finally growing aggressively.

Tropical Fruit Discussion / Re: Seedling Mango tree thread
« on: October 15, 2020, 11:25:40 AM »
Interesting thread Simon.

I'd like to expand on one of the genetic issues.

Iím especially interested in Polyembryonic off types because of the potential for superior fruit due to plants produced through selfing which sets the traits of that particular variety. A selfed mango flower is a flower of Sweet Tart for example, that was pollinated by itself(Sweet Tart). The resulting seedling is 100% Sweet Tart genetics but it is not a clone because there is a re arrangement of the chromosomes.

To be clear, its not only re-arrangement of chromosomes, where the arms of the chromosome arms inherited from the grandparents cross over and you get patchwork chromosomes mixing up grandmas and grandpas genes on a single arm. There's also the fact that the child plants can have either arm paired with itself or paired with its opposite. Which gives rise to the phenomenon that with regard to any particular gene the child can inherit one grandma copy plus one grandpa copy, or both grandmas copies, or both grandpas. So if the, just to have fun, 'fiberless' gene A is dominant and comes from grandma, and A' from grandpa but has a bit of fiber then the self cross child can be AA, or AA' or A'A'. The second of these is genetically equivalent to the parent plant, but the first and last effectively loses one of the grandparent's genes. By observation you would keep either AA or AA' variants as both being fiberless, but reject A'A' for having fiber. But you wouldn't know if you had AA or AA'. At some generation it would go to AA by chance (1/3 of the selectants are AA) and become fixed because A' would no longer be in the genetics anywhere. After that A would always pair with A.

To put it another way, 100% of the child's genetics comes from the self-crossed parent, but 100% of the parent's genetics is NOT preserved in the child. There's always gene variants being lost (going homozygous to one of the grandparent's versions). That's what 'sets' the traits. Eventually it happens to all the genes (after 7 generations of selecting for desired characteristics is the rule of thumb). At that point instead of having AA'/BB'/CC'/DD' etc., you have AA/BB/CC/DD with largely identical offspring and the only diversity is created from rarer genetic events.

Anyway, its a fascinating aspect of plant breeding that isn't always clear. 

So i'm following your guidance Mark and Spaugh. With regard to the pump and sprinklers, the Grundfos constant pressure controller goes down to 40psi. There are micro sprinkler heads that will function at 40psi (not all though). Do you recommend using those heads (like this? or putting in pressure regulators at each row? I guess that might depend on the elevation change?

Interesting air layer method. Isn't it a pain to need to replace the water to keep it fresh, and from misquitos growing in the water?
I prefer the normal method with cocopeat/moss since you can forget about it until it's ready to cutoff the tree.

And i'm sure the peat moss wrap works better too. I think this method is good for those of us that are checking every one of our experiments every 12 hours. Has to be fun to watch grow. I think i usually end up leaving my wraps way too long, not knowing how many roots have grown.

Iíve had one in the ground for about six years. First crop this year and plant is Finally growing aggressively but the fruit donít ripen entirely. They eventually  drop as hard yellow BBs.

year old, but just showed up in my youtube feed. i like the being able to see the roots grow part.

Use green papaya to tenderize meat

And leaves too right? never tried myself

Antibiotic peptides is a very cool new field. Should make a big impact on human health in the coming years as well.

Very cool.

Not yet. Too attached to the ocean still.
