Cherimoya varieties for hot weather regions...

[digigarden]

Cherimoya Cumbe from peru fruits in Dominican Republic low-mid lands confirmed 

If it grows in DR is low lands it should grow in Florida I imagine?

Well i don't think it would grow at sea level i could be wrong but In a way i suppose doesn't get as cold as FL  but it also doesn't get as HOT as FL... but hey what if you shade it a bit during summer?

High temperatures (over 80 ish degrees) cause the fruits to stop developing and make the pollen sterile in Cherimoya. That is why they can be grown in Puerto Rico or Hawaii and not Florida. I think we could fruit any Cherimoya with the right cultural care. It would need to defoliate in September and bloom in October so that the fruit could develop over the cool part if the year and then finish ripening in April before things got too hot.

Has anyone attempted this September defoliation method for Cherimoya in a warm region yet? It sounds promising.

I have not been able to try it, yet. My cherimoya is a seedling that is still in the juvenile stage.

Get the ones grown in Spain
Fino DE jete if I'm not wrong
And they are best ones

September has arrived and I’ve been considering defoliating my cherimoya to try to induce flowering. Anyone trying that this year? Does stripping leaves from a single branch work or does it need to be all/most branches?

You should be able to do individual branches. I will havr to wait to try this on my seedling cherimoya until it starts blooming. On a similar note, I do have bloom on a single branch of my Painter Cherilata where I cut it back about a month ago.

[Growfoodsurf]

Okay wow. Just a lot misinformation here in this post. I worked on the majority of the original cherimoya groves planted in San Diego from the 1960s.

First let me get started that cherimoya originate from... Figure it out homie.

Lots of blooms happening. No one with fruit.

I realize that my views are not conventional on this topic. When I read the original comment, I pondered whether to share the results of my research or not. I was fairly certain that people would question it unless I had pictures of my own tree. Skepticism is understandable. Since other people had similar questions, I decided to share what I had learned inspite of this.

First, John Painter's cherimoya tree did get production of poorly formed fruits that fully ripened at about tennis ball size for many years here in Florida. Popenoe apparently reported similar results. Fruit is possible here even though they are poorly formed and production is very low. I believe that with a proper understanding of the problem and the correct cultural care the issue can be solved. I have based my comments and thinking on two scientific papers. The first was a study done in Japan detailing the exact effects of heat stress on cherimoya. It is 108 pages. I have not re-read it, but as I recall heat stress was most harmful to mid-size fruit. This explains why typical season cherimoya fruits stay small in Florida--mid size fruits in May get zapped by the heat.

If fruits could be produced in the off season, our weather would be moderate and within the range that would not cause heat stress. This is where the second article came in. It is a description of the procedures for prodicing off season cherimoya in Spain. While I am not certain of the exact timing for Florida conditions because I have not had the opportunity to experiment with that, yet, the logic is sound and science based. I have linked both articles for anyone who would like to draw their own conclusions.

I am experimenting with cherimoya varieties in my hot SW Florida climate, its even hotter than Pine Island as Im over 20 miles inland and get higher highs most everyday in summer expecially during the heatwaves.

I grafted some varieties on different roostocks to evaluate but all of them seem to drop leaves and stall growth these last few months. plants are young and sample sizes are small but DR white looks the best so far.

Regarding cherimoya or annonas in general offseason fruit. I first recall when i visited the late Wayne Clifton at his home he was showing off his Dream cherimoya tree. It was febuary 27th and he was selling me scions from his Dream tree. He pointed out the branches he stripped the leaves prematurely on to induce off season flower and fruit. He had fruits fairly large on his Dream annona at this time and flagged the branches with flagging tape to keep track. When the climate is mild the annonas especially the hardier didnt defoliate so stripping the leaves is important to get them to flower as they flower on new growth.

 here are photos of Wayne Cliftons Dream annona tree from my visit back in in Feb 2017

[Galatians522]

Nice pictures, Luke. I really liked Wayne. Sounds like we visited him about the same time. I was there in May of 2017. I didn't take any pictures, but was also amazed by the size of the fruits. I hope the articles are helpful in getting your cherimoyas to fruit.

I have noticed on the small 1 gallon seedlings I grafted that there are some differences in heat tolerance. Im in Texas and it gets hot here.

Look at how badly chaffey cherimoya got sunburned in the pic. Dropped many leaves. Booth and pierce did better but still sunburned.  Cherilatas and atemoyas did the best, no surprise there Im sure.

[Growfoodsurf]

Okay today is the chance for all the California homies to post picks of cherimoya heat tolerance. I just read 110 in the shade couple days ago. Post your burnt full sun trees.

But also what's more important is fruit hold, who has fruit set still holding in 110 heat?

I have one that is beautiful looking still while in full sun. It hardly has any burnt leaves. We hit 111. I made sure to water everyday. Fruit is still on, but has definitely paused growing. We shall see if the fruits resume getting bigger.

[spaugh]

ill post pics, my trees are fine.  still going to have a big crop in a couple months.  was 112 the other day, and 107+ for 5 days straight.

[spaugh]

some minor leaf browning going on but pretty much nothing out of the ordinary.  Fruit certainly are not falling off. 








this is tree I stumped to do top working on next year.  New growth not damaged from the heat wave.

Do cherimoyas increase in size through fall? Mine seem small right now.

Yes, they will size up over the next few months. 

[Growfoodsurf]

That's impressive. I got tip burn on a lot of my newly planted grafted treesbin partial shade. Not big deal, just an opportunity to rto cur back and get wider growth. Worst performance from avocado, young grafted tree trees with burnt bark already. I reckon it hit around 120 by me.
