Inga can be hacked back down almost to the ground every year and grow back fine.

I have a large female Garcinia benthamii which is also 5+ meters tall that will occasionally  set the odd miniature seedless fruit that ripens to a light orange colour. The tiny amount of flesh in these fruit has a very pleasant taste, so it would be nice to get some full sized fruit. I too find it hard to cut out such a lovely big tree, next season I will try to use pollen from my G.xanthochymus in an attempt to get fruit set.

Luc, above is true. I've seen lone 'female' G. hombroniana set small fruit without viable seed inside.

Cold fronts (and the occasional hurricane) is biggest climate concern Rob. It won't take temps in 30s F to do damage. Temps in 40s F can do damage. You can also see major leaf desiccation a bit after a good cold front blow through. The tree grows slow enough as it is, you dont want damage occurring and setting it back. I would construct a simple frame around the tree that you can wrap with a layer of poly and frost cloth for when those annual cold fronts blow through.

Any idea on its cold hardiness? Assuming it’s not great if anything like Florida Hass.

Original Super Hass tree was even further north than you. Give it a try

These are the first Luc Garcinia fruits out of Mexico.

Sadhu fruited his in Puerto Rico a couple years ago

Thanks Brandon. The fruit was good, but yeah, a little bland. Definitely worth eating. It was a bit snotty in places, so my daughter and I ate a bit and froze the rest for smoothies.

Have another nearly ripe fruit on the tree, still a few flowers, and several small fruits that recently set. Seems to be pollinating better now. I did not do any hand pollination on the recent fruits/flowers. 

Best to eat them before they get fully yellow (similar to your second picture rather than the one I quoted). They have a more complex flavor and not nearly as "snotty".

Water isn't entirely at fault, it's the temperature fluctuation in addition to our dry conditions.

Have you noticed lately it's been in the low 40's in the evening and high 80's in the day?
Yea, that will cause some good cracking to just about any fruit.
Happened to my longans, mangoes, cherimoyas, atemoyas, jujube + many others last year.
The mangoes to go about the size of a child's fist and starts cracking down the center.
Maha, Sia Tong, Okrung, Keo Savoy mangoes.

I'm not sure if you measure your parameters inside your greenhouse, but I try to keep my humidity, temp and CO2/O2 levels at safe levels.
So far it's helping this year, because it is a challenge to grow anything tropical/sub-tropical here in the Bay Area.

Plus possibly your potting mix. Mangos like well draining soils - too much water will be an issue especially if you're giving it water every day in a container with a mix that holds too much moisture.

Where?

Guessing either island of Reunion or Mauritius (just east of Madagascar) as that is where Tropical Storm Fakir just passed by

Got nice seacrest 3gals earlier this year. Haven't tasted them but have heard good things.

Holy cow, that's fast. You must be feeding it well.

I had thought it was older, but Seadation and I tentatively dated it back to 5 years old from seed.

Either that or there is a mistake in his records? My guess it that there is a mistake.

I did some research through old photo's and text.  Confirmed my tree is in fact a 2013 seedling.  Seadation gave me the small seedling August 3 2013.  I planted it right away in ground.  It is in an area of my yard that has better soil than the rest of my yard.  In an area where the previous homeowner kept pigs and chickens, topsoil is black, and gets irrigation.  It is planted between 3 mango trees and a Mulberry, getting 70-80% filtered sunlight, 20-30% direct sunlight for most of its life.  I give it some slow release fertilizer, and occasional foliar sprays of the "Patrick mix" ( chelated Iron, Southern Ag citrus spray, occasionally mixed with foliage pro). 

Obviously it is happy where it is planted.  Seems like a synergistic effect of proper sunlight, water, food, and genetics.

Yeah, could be genetics mixed with the just the right spot and nutrition. I've noticed, when growing many Garcinia sp from seed, sometimes there are a couple seedlings that end up growing much stronger and faster than the rest of the batch despite the containers being in the same exposure, getting same water/fert treatment and I attribute it to genetics. I have seen some 2ft taller than others at the same age and you'd think they were years apart in age.
