Hi everyone. I want to know what fruit this is. I bought them frequently at streets stalls and markets in Ecuador in 2013. I foolishly took few photos and even removed the pit before taking the interior shots. (I can't even remember what the pits looked like.) The flesh was stringy, maybe with a papaya-like flavor. The skin was greenish brown. Note the nub at the end of the fruit, as well as the longitudinal striations radiating from the nub. I don't think this is a mamey sapote. Any ideas?

Hi all,
There seems to be increasing interest in white sapotes, as I think there should be. It's one of my very favorite fruits. I very near Sebastopol, Sonoma County Calif. and have planted 11 white sapote trees outdoors (and 1 in a greenhouse).

But I am becoming more and more doubtful that these trees will ever be very productive. The largest of my trees keeps aborting its blossoms. I have heard similar stories from others, plus stories of trees dying back badly in cold snaps. In fact, I have never heard any verified accounts of large and consistently productive trees north of the SF Bay watershed. There is (or was) reportedly an orchard of white sapote near Chico, Calif., but I don't know if the trees were ever productive.

All the accounts I've heard of wildly productive white sapotes come from SF, Richmond, Fremont, the Peninsula, other bayside cities, and south.

So, does anyone know if there any large and productive trees -- OUTDOORS -- in Sonoma County? Napa? The cities of Davis, Woodland, or Sacramento?

I've put too much work into these trees to back out now but I wonder if they might wind up being fruitless conversation starters.

The question struck me the other day as I was grafting figs. If rootstock can slow or accelerate wakeup time, ripening speed, and hardiness of the plant overall, wouldn't there be way more discussion about selecting the right rootstock for the right cultivar? In the world of figs, there is endless fretting over how early a given variety ripens, yet we graft willy nilly onto almost any rootstock available. (At least, I do.) Now that I've grafted over half my collection, I wonder: Does a late rootstock slow down an earlier grafted cultivar? Or does the early cultivar draw the rootstock out of its slumber and force accelerated performance?

More specifically, can I expect a certain measure of frost hardiness from a lucuma cultivar if it is grafted onto some other Pouteria species?

Curious what y'all think.


Iím putting it in the ground now, full sun. Should I set up a shade structure? If so, how long should I keep it in place?

Tropical Fruit Discussion / Casimiroa edulis vs C. tetrameria
« on: February 07, 2024, 11:32:51 AM »
Question about a variety of "sapote": Is the "Chestnut" variety part of the C. edulis species (white sapote) or C. tetrameria (wooly-leaf sapote)?

Howdy. Iím planning to put 2 carob trees in the ground soon. I wonder if I need to fuss over the soilís properties the way many of us do when planting avocados. Does anyone have experience with carob they can share? Should I mound up with sand and loam before planting? Are carob trees as sensitive as avocados to mucky soil? I ask because the literature, as with most tree species, says carob trees require well drained soil.

Background: My soil is relatively heavy clay-sand loam. Figs, apples, pears, grapes, persimmons, stone fruit, mulberries, and citrus do very well in this native soil. Avocados have grown very slowly, leading me to believe mounding is necessary.

But is it necessary for carob?

Thanks for any feedback.

Hi yíall. This question has been asked a thousand times but I canít find the nuanced info Iím looking for so am starting a new thread.

I have a familiar problem: heavy clayish soil that mucks up when wet. So, Iím building avocado mounds. Iím building them about 2.5 feet high and 8-10 feet across. I am building the mounds with a blend of sandy loam, pure loam ordered from a soil provider, coarse sand, a little gravel, and lots of very rich topsoil, including mature compost.

Am I doing this correctly? The uncertainty in my mind is how much organic versus mineral/sand/rock components to use. I want the trees to remain elevated indefinitely. Soil built mostly of composted organic matter sinks and eventually evaporates away. Thatís why Iím going heavy on sand, loam, etc. Of course, I donít want to overdo it and eind up with poor sandy soil.

Any tips?


Tropical Fruit Discussion / Is this lucuma, canistel, or Ö ?
« on: January 08, 2024, 07:27:48 PM »
Hi all. I found these fruits at a small market in San Francisco. The fruits were not labeled and the vendor and I had a language barrier between us. Can someone tell me what Pouteria species this is?

Tropical Fruit Discussion / White sapote aborting all its blossoms - why?
« on: October 28, 2023, 09:16:52 AM »
Hi everyone. Iím reposting this question from a separate thread to give it a bump. I am having pollination problems with my Vernon white sapote. It made a flush of blossoms this fall, but nearly all have aborted. This happened in the spring, too--hundreds of blossoms, but no fruit. The tree is otherwise healthy and is putting out new growth. The tree, probably about 6 years old and 6 feet tall,  is capable of fruiting, and it did so in 2022 (after blossoming in spring 2021). So, why is it failing now?

FYI, I donít follow any sort of fertilizing routine. Thdd Ed tree is growing well enough that it doesnít seem to need it.

Thanks for any advice.

Tropical Fruit Discussion / Do ants damage white sapote blossoms?
« on: October 12, 2023, 07:16:46 PM »
Ants have descended upon (well, ascended) my small Vernon white sapote's blossoms. I assumed they were just gathering up nectar until I noticed today that the tiny little "fruits" in the middle of the blossoms are starting to turn brown. They have not yet fallen off but I fear they will, and I'm wondering if the ants are in some way damaging the blossom. Could this be the case? Do I need to repel them in any way? I know that some ants are considered beneficial for avocados. I hope it's the same for white sapotes.


My WS is flowering now. Iím in zone 9, high likelihood of temps as low as 29 or 28 this winter. Anyone have experience to suggest what will happen to these flowers?

The tree is young. It flowered in March 2021 and made a first crop of 8 fruits, ripe 10 months later. No flowers in 2022. In March of this year it flowered again, but dropped them all. Now this. Trying to understand this creature.

Thanks for reflections.

Tropical Fruit Discussion / Best source for lucuma seeds?
« on: September 05, 2023, 08:57:42 AM »
Hi all,
I'm looking for lucuma seeds. I'm in Sonoma County, northern California, and am interested in growing a lucuma tree or two. I have never seen lucuma fruit in California markets, so I am pondering the best approach. Any recommended sources?

And while we're talking lucuma, has anyone in northern California had success with lucuma?


Tropical Fruit Discussion / Is "World's Best Mulberry" overrated?
« on: June 12, 2023, 11:27:05 PM »
Is the ridiculously named World's Best Mulberry, by any chance, generally underwhelming? I ask because I have a tree that a friend started from a cutting either 3 or 4 years ago. It has grown at breakneck pace and, after a heavy pruning last winter, is now a spindly 10 feet tall, with three main branches loaded with fruit. The berries are swelling up and ripening by the hundreds, and they look beautiful. However, they are terrible - sour, a little watery and barely sweet at all. Is this normal for WBM? Will the fruit get better over time? How much better? And how long might I have to wait for this variety to live up to its name?

Thanks for any feedback.


Hi everyone. My largest white sapote tree is struggling to put out new growth, and I can't understand why. For at least a month it has been pushing buds from the tip of its main stem (which last year grew about three feet). But continuously, the new growth seems to dry up, fizzle out, fail - however you want to describe it. I have checked the tree at night and have seen no earwigs (though last year they were all over this tree). I also have seen no slugs on the tree. Can anyone guess what is happening to these new little buds and why they won't grow beyond this stage? Notice in the pics how the ends of the tiny leaves are blackened. We have not had a hard frost here for about 6 weeks.

Does anyone know what this variety is, or what Morus species it is from? Thanks,

Tropical Fruit Discussion / Is my white sapote sick?
« on: January 09, 2023, 02:16:17 PM »
Hi everyone. I have 7 small white sapotes in the ground. They are young but have grown rapidly in the past year. Now, a couple of them are showing dark patches on their leaf ends. Whatís going on? My soil is loamy clay, so it tends toward damp heaviness. But most fruit trees thrive on my property. - figs, mulberries, apples, stone fruits, etc all very productive. But Iím worried that the white sapotes are suffering from wet feet. What would the symptoms of this be? Though my soil is heavy, I am on a 10 percent slope with little or no ponding of water. The past 3 weeks have been very very rainy. I did not plant my white sapotes on mounds.

Photos are attached. If you think you know whatís going on, please offer advice. Thanks,

Hi everyone. I am in northern California and am hoping to plant a lucuma tree or two, and I need either seeds or seedling trees. I know nothing of cultivars in this species, so I will leave that for a later discussion. For now, does anyone have a suggested nursery to help me get started?


Tropical Fruit Discussion / Frost hardiness data for White Sapote?
« on: November 26, 2022, 11:00:27 AM »
Hi everyone. I am zone-pushing with white sapote as well as cherimoya in Sonoma County, California. I would love to find some good data on variety-specific frost tolerance in white sapote. Information on cherimoya would be great, too, though I suspect it is even scarcer.

We read in nursery literature that Mexicola avocado is hardy to 18, Stewart to 18, Bacon and Zutano to 24 and 26, respectively. Etc...

So, what about white sapote varieties? Which ones can withstand the most severe blasts of frost? And how low can they go? Anyone have data? I ask as someone who has 6 seedlings in the ground and wants to graft the right cultivars this spring.

Thanks very much!

Tropical Fruit Discussion / What is eating my white sapote leaves?
« on: September 28, 2022, 03:29:11 PM »
Hi everyone. I live in northern California, where some small critter -- presumably a "bug" of some sort -- has been munching away at my white sapotes' leaves, especially but not entirely the new growth. The small trees are vigorous and trying diligently to get bigger, but this pest is hindering progress. I would like to identify the culprit and take care of it, hopefully without having to use chemical products. I originally suspected this was earwigs, but after setting out baited oil-and-soy-sauce traps, which have worked well in the past, but getting no earwigs, I wonder if something else might be at work. That said, it might very well be earwigs as they have been problematic in my yard before.

Ideas? Advice? See the attached pics.


Hi everyone,
I joined this forum a few days ago. I own a piece land in Sonoma County, California and have planted it with figs, Asian pears, persimmons, pawpaws and other temperate fruits. I have also planted avocados and white sapotes -- and it's the white sapotes that I would like to discuss. I want to know if other people in my climate zone -- 9B -- and especially in my immediate area have had success with white sapote and, if so, what extra care (if any) they require. I planted a Vernon white sapote three years ago. In its second spring in the ground, it set blossoms, and it made 8 nice fruits in the fall of 2021. I do not recall the coldest temperatures we had that year -- maybe around 30 or 31. So, it can be done, at least in favorable years. But we do have considerable frost here. In February 2022, temperatures dropped to 27 degrees here. While the literature suggests white sapotes will withstand 22F, my 5 young trees were defoliated. They have rebounded nicely, but they made no blossoms this spring. I am wondering if I am facing a future of sporadic white sapote production, at best.

A few questions:

Is it common for white sapote trees to thrive in Zone 9B but very rarely make fruit? (This is the case for many avocados in my neighborhood.)
At what temperature do white sapote blossoms suffer frost damage?
Have any of you seen white sapotes fruit on an annual basis even when subjected most springs to high-20s frost?

Thanks for any advice, encouragement or specific info you can offer.
