I find snake fruit to be on par to roasted chestnuts.

Cherry of the Rio Grande comes from the South of Brazil (Zones 9-10) in semi-deciduous forests where organic matter and mulch helps.  These trees can grow up to 10 meters tall.  partial sun to full sun.  They are generally planted in native soil in Brazil, but since you put amendments it, it is likely working to build root structure.

So long as it is watered well, it should recover, though I wouldn't fertilize it for a while. 

Which has more resistance toward anthracnose?  I've heard Neelam has some resistance, but please correct me if I am wrong.

How does Sugarloaf hold up to anthracnose and what is its fruiting season?  (Mid-season?)

Regarding the Trapp chippers in Brazil, the cheaper ones are underpowered and can't do more than 2".  There are commercial Trapp's that are much better, but they come at a price.

I just saw this posting and now I'm interested in finding more about it.  It looks like it may be a relative of the Bourbon vermelho (Red Bourbon), a flavorful mango, though it is very fibrous.  When I return to Brazil in October, I will see if I can find some to try.

Jeff,
You wrote:  "If one is unwilling to spray fungicide (and especially those living inland or in a rural setting, where humidity is higher), then only a handful of cultivars will produce well in those circumstances."

Which are the varieties that will produce in these circumstances, and can you tell me which are more top tier.  My trees are in the Brazilian rainforest and I have been struggling to keep fruit on my trees.

In Southern Brazil, I have many annonas in partial shade that do quite well.  Due to wind damage, we find that the protection of other trees are helpful.  We have high yields and sweet fruit.  Our climate is very different than in Manaus, which is very hot and humid year round.  Here we have cooler winters approaching freezing, and the trees do fine.

Good luck on your project.

Anestor helped me on numerous occasions.  He was a great source of information and kind person.  My heart goes out to his family.  I only wish I could have met him in person as we both have sítios in Santa Catarina Brazil.  Goodbye my friend.

On my farm in Brazil where annonas are native, I never see splitting of my fruit.  I don't think cold nights are much of an issue, so long as the trees are well irrigated.  In the winter in Brazil, temperatures can fall into the 30's (near 0C) and still my fruits don't split.  As far as rainfall is concerned, we have a lot of rain all year long.  I think this constant irrigation is the reason why our fruit don't split.  We also are humid much like Florida.

I'll give it a try.  Thanks Alexandre for the lead in SP.  Do they do mail orders to send to Santa Catarina?

I have a large astringent persimmon that I would like to top-work to a sweet persimmon variety, if that is possible.  Will this work and will the graft take?  If this is possible, does anyone know a good variety?
