The guy in the video says that he has two kind of guanabanas. One requires manual pollination, which they perform from 5 to 9 in the morning, the other does not require manual pollination.

He also says that unlike other fruit trees, guanabana needs lots of fertilizer for good production. If it doesn't get enough nutrients, it aborts fruits and flowers. They apply four kind of fertilizers:
- Guano - bird manure
- NPK 15-15-15 every three month
- Organic matter (very important he says)
- Foliar fertilizer (doesn't tell what kind)

In my opinion this guy doens't have any scientific background. He just spills stuff into the ground without much knowledge, no high performance tecniques.

In most places Guanabana trees will need extra Zinc to perform well.

In the beginning he says that he started with 900 trees, 70 grafted and 830 seedlings (criollos) He said that he gets as much production from the 70 grafted trees than from the criollos. The grafted trees do not need hand pollenization  but the criollos they pollenize by hand every morning to get good production.  The  organic fertilizer is chicken manure. Clains that they need a lot of fertilizer to produce.
I wonder if we have that grafted variety in US?

Ideally would be to get some of the bud wood for what they call "grafted" seems to be a superior variety.

Hello Ed.

I was fortunate enough to meet one of the big commercial growers in Colombia last week. ( he produces 1/3 of all the mangoes in the country ) he also spoke to me about the Giant Guanabana, which he also grows commercially, he uses some kind of freeze dried process for them.

He invited me to visit, but i cannot afford a trip to Colombia any time soon. I may try and ask him to mail me some seeds, but not sure if they would make it in the post. from Colombia to the D.R.

I so want to get seeds from this variety, have you had any luck?

If the seeds are sent in a slightly moistened medium, such as sawdust, they should do well in a package for 2-3 weeks.

Thanks Guanabanus,  I have a question, regarding the seeds, do they generally come up true to parent?

I lucked out, seems some years back, the dept of agriculture, distributed a few Colombian Guanabana trees here in the DR. and I have found a source, I will be able to get a small tree soon.

I was wondering about the seeds, because I know a few people in the US may be interested in this variety.

Not necessarily true-to-mother-tree from seed, but if the seed came from a self-pollination, it will be very similar to mother tree.

If you know the name of the Colombian guanabana cultivar you may be able to get it from GRIN. They have cultivars in the Miami and Mayaguez experimental stations. Here at the Hawaii state experimental station i have seen also some guanabana cultivars, but i don't have a list of them at hand right now.

Colombia probably has the greatest variation  and genetic resources of Guanabana.
Commercial varieties from there that are grown in Brazil are the 'Morada' (most recommended), the 'Lisa' (i.e., "smooth", not to be confounded with the Floridian atemoya), and the 'Blanca.'  A more recent selection in Colombia, by the ProFrutales company, is the 'Elita.'

A selection in the Philippines is the 'Aguinaldo'.

I have never had plants of any of these.

In many places soursops are simply categorized into three general types, "sour", "sweet", and "fiberless."

Har Thanks For The info, I will ask my Mother-inlaw to investigate those cultivars with the local growers to see if i can get my hands on those types of Guanabanas, so the Morada is the Best Guanabana Cultivar in Colombia ?

The 'Morada' is (or at least was) the most recommended in Brazil:  most productive and less susceptible to trunk borer.  My information is from 1994.

Guanabana in Panama is very similar to guanabana in Colombia... there are 3 main varieties and then there are sub varieties.. (sweet, acid and semi-acid). Panama was once part of Colombia so many fauna and flora are the same.

 The main problem here with growing guanabana is an insect that can bore through newer growth leaving an opening for fungus. It is not clear whether the insect carries the fungus or the hole just allows the fungus to grow.  I would like to hear if anyone has had any success treating this problem organically... Given the intense rainy season down here fungus can easily get a foothold and destroy new rees or newer growth on the tree. Guanabana is a very sensitive tree and has a lot of natural enemies.

Good fertilization is a must for guanabana fertilizer heavy in nitrogen and phosphorus is suggested for newer plantings. As time goes by a good 10-10-10 or close is better... boron especially and minors are important for health. Chicken manure is widely used here because it is so cheap.

I dealt with this branch borer when I was a teenager in northern Brazil.

Inspect your trees weekly.  Prune off infested branch and cut until you see that you have cut the grub or pupa in half.

I've use organic chicken manure and tripe 15. So far no fungus or insect problems some leave burn in the hot dry summer. here is a pic of my guanabana it has doing real well this summer

I have many flowers in my guanabana but they don't get pollinated. I tried it by hand but still don't know if it worked.

The ants now have a nest in the flower and it is full of black stuff that is the male pollen i guess. If i understood it right then the flowers start as female and if not get pollinated become male flowers with the black pollen. So probably that flower is not pollinated but it is still growing.

I found this site which is about all i can find about handpollination for guanabana
