Here were I live, in Panama, Central America, there isn't any significant production of cherimoyas.  In fact, the only commercial source - I know of - local to Panama told me that the season is finished.  There are however imported cherimoyas from Peru.  I was curious about their seasonality, so, I asked the people who import them from Peru.  And was VERY SURPRISED to hear that they are available year round.  They plan on bringing in a shipment every 15 days, year round!

How is this even possible?  How do they get the cherimoyas to flower year round?  Is this something that I could do with the few annonas I have?  This is definitely something I would love to learn how to do it....

I grafted a couple of dream atemoya scions onto cherimoya rootstock and a couple of sugarlata scions onto sugar apple rootstock.  This was about a month ago.  The scions still "look" and feel fine (they are wrapped in parafilm), but they have not grown.  The rootstocks on the other hand keep producing new growth, but every couple of days I remove anything that grows below the graft.

Should I leave this as is for another month?  Or should I try to re-graft these scions?  I am a bit clueless....  Is there a way to know if the scions are still alive?

I was SO happy with my grafts too....  :D

Thanks for your comments.

Tropical Fruit Discussion / What do you guys think of Cumbe cherimoya?
« on: October 11, 2021, 01:47:32 PM »
Here in Panama we don't get much annonas commercially.   There is one grower - that I know - that sells sugar apples, and there are a couple of cherimoyas you can get.

One cherimoya variety we do get is "Cumbe" which comes from Peru.  It is good, but honestly I don't find it outstanding.  I prefer sugar apples.  There is a local cherimoya variety which tastes better to me, but the fruit quality is somewhat variable (probably due to agricultural practices).

How does Cumbe compare to other of the nice cherimoya varieties that you get for example in California?   

Tropical Fruit Discussion / What is wrong with my sugar apple leaves?

What do you guys think is wrong with my sugar apple plant (Annona squamosa)?

I am guessing this is some sort of nuritional defficiency, but I donít know what it could beÖ

The tree is in a 10 gallon pot.


Tropical Fruit Discussion / Traveling to Los Angeles
« on: September 13, 2021, 11:51:40 AM »
Due to unforseen circumstances I will be traveling to Los Angeles this week. 

Do you guys know where I can purchase some nice Atemoyas and/or cherimoyas?  I will only be until Sunday but maybe I can try something nice.  I have read very good things about California annonas.


Tropical Fruit Discussion / Question about australian atemoyas....
« on: September 08, 2021, 01:05:41 PM »
I have read here and elsewhere how good atemoya varieties from Australia are.  Especifically I have read about "Paxton prolific" (KJ Pinks) and "Hillary White".  Don't know if they have newer/better ones. 

What I was wondering is, why they aren't available in the United States (at least I haven't seem them)?

Are these varieties patented in some way?  Is it illegal to grow them outside of Australia?  What is the story on these?

Thanks for any juicy information to satisfy my curiosity  ;)

Tropical Fruit Discussion / What is the "Giant Sugar Apple"?
« on: September 08, 2021, 12:18:49 PM »
Han Sen is selling various nice seeds.  One of them caught my eye.  Something called "Giant Sugar Apple".   What is this?  Is this a hybrid of A. squamosa X reticulata?  Or is this a different species altogether?   I searched "Annona mucosa" but that points to Rollinia, which is a very different looking fruit.


Tropical Fruit Discussion / Hybrid vigor and Annona hybrids
« on: September 07, 2021, 02:59:40 PM »
I studied Food Science in college, but in my office I had a good friend who was doing a PhD in agronomy.  He knew a lot about plant genetics, and he was the first person how explained to me about "hybrid vigor".   This was in Texas A&M.  We were working mostly on cereals, particularly sorghum.   The basic concept is that you have two varieties, each one with specific qualities.  If you interbreed these varieties, you obtain a hybrid, which has BETTER properties than each of the original varieties.  Hence the term hybrid "vigor".    A "problem" with hybrids however is that you typically can't propagate them properly by seeds, because the resulting plants are not true to the parent hybrid, but rather you get a lot of variability.

Inter-species hybrids are even more interesting - at least to me -, and the things that have been done with Annonas I find fascinating.  Atemoyas (A. squamosa x A. cherimola), Cherilatas (A. cherimola X A. reticulata [custard apple]), Sugarlatas (A. squamosa X A. reticulata), and other things people are doing I find fascinating.

I was wondering if anyone here is working breeding annona hybrids?   I have a ton of questions....  :) 
For example, when breeding atemoyas, does it make a difference if the female flower is a Sugar Apple or the Cherimoya?  Another question, I have seen that people take an Atemoya female flower and fertilize it again with Sugar Apple pollen... What happens when you do this?  Is the hybrid vigor mantained? 

I have been searching for more information on this subject, but can't find much....

I am new to growing citrus trees.  I don't have much space so I intend to grow them in containers.  I have my first one which is a still small mandarine orange tree, later this year I am adding a persian lime and a valencian orange trees from a local nursery. 
I was thinking on using fertilizers that are readily available here: Urea, 12-12-17, Bone Meal and Epson Salt.  I mixed these up to try to mimic somewhat the 5-1-3 theoretical ratio of citrus needs (if I understood this correctly), and got a fertilizer with a 19N-9.3P-11.7K-1.4Ca-0.3S-0.22Mg (this has a proportion of 5N-2.4P-3K which I figure is close enough).

I have also read and seen a bunch of videos that recommend monthly feeding for fruit trees in containers (citrus, figs, etc...).  I was thinking that it would be wise to follow this recommendation.

The question is how much to add to each tree of this fertilizer each month?  And then I imagine that the rate will vary depending on the size of the tree.... For example, how much:

1) When the trees are small in a 1 gallon pot,
2) When the trees are medium sized in a 5 gallon pot,
3) When the trees are producing on the first couple of year,
4) When the trees are over 2 years of age.

Thanks for any recommendations you can give me.

Citrus General Discussion / Grafting citrus fruits
« on: July 15, 2021, 11:15:53 AM »
I am new to citrus... trying to learn as much as I can.

I live in Panama City, Panama.  Here in Panama most citrus trees are grafted on "flying dragon" rootstock, probably most commercial growers do.  Some are grafted onto other things.  HLB has become this year a problem throughout Panama.  The first cases appeared in 2017, but this past year it has spread.  Panama is small, so that didn't help.

What I wanted to ask.  I have read that some people do a double graft (I don't know how it is called).  They graft the citrus tree onto a lemon and then the lemon onto a sour orange for example.  So there is an intermediate plant.

Wow... This blew my mind!  This is very interesting.... Why is this done?  Where can I learn more about this?

I am interested in an atemoya plant of the "Paxton Prolific" variety.  This variety is also known as "KJ Pinks".   I would need it shipped to Miami, Florida.


I am interested in getting an Atemoya "KJ Pinks" (preferably grafted on sugar apple), and an "Owari Satsuma" mandarin (preferably grafted on "flying dragon" rootstock).

I need these shipped to a Miami address.

Do you guys know where I can get these?


On an article published by the University of Florida ( the sugar apple variety "Lessard Thai" was rated highest in quality and recommended.

I would like to get one plant of this variety, but I fear that those being sold on the internet might be grown from seeds.  Are sugar apples true to seed?  I am under the impression that they aren't, but I am not 100% sure....

In any case, do you guys know how I can get a true-to-type plant shipped to Miami, Florida?



From what I understand some varieties of mango are much more resistant to fruit files than others.

Do you know which good varieties are resistant to fruit flies?  I wanted to try the varieties "edgar" and "ataualfo" but would much prefer not to use traps because of where I will keep these trees (i.e., far from where I live).


Tropical Fruit Discussion / Small fruit trees for shaded spaces
« on: June 07, 2021, 05:25:19 PM »
I have a small area in my backyard that is quite shady (from trees that are around it).  Are there any tropical/subtropical fruit trees that can be grown in the shade?   

I was thinking that maybe some citrus (mandarines, lemons) in containers would be a good choice.... What do you guys think?


I live in Panama City, Central America.  Climate is hot and fairly humid.   For some reason atemoyas are fairly rare here, even though I think that they should grow well here.   Sugar apples grow well here.   Cherimoyas don't grow well in the lowlands (at least I haven't seen them in the lowlands).

I would like to try growing atemoyas here.  Which varieties would you guys recommend that don't require hand pollination?   

Another question I had:  Is it feasible to keep an atemoya tree small by pruning.  Say for example at 7ft?
