It depends on the spondias. The spondias we call jocote, I think that is s. purpurea is grown from cuttings here in CR.  Spondias mombin does germinate and starts all over the place as a volunteer on my farm.

Commonly, champedek seeds germinate nicely then when they need to transition from being supported by the seed to developing a good root system to continue development there is a problem with a lack of good root development and the young plant gets weak.
Anyway, that can happen frequently enough that itís common for champedek to be grafted onto jakfruit.

That would be great Durian lover. I was in Bali in the 70ís and it was wonderful. However, Iíve been avoiding it so to preserve whatís left of those memories. But for a fruit trip it could make sense. Iíll let you know. Many thanks.

If that damage was here I would say leaf cutter ants. They make clean, half moon, cuts like that.

Instead of trying to wrap very tender material we use clips and bag the graft. No wrapping necessary.

Another good practice is to use champejak for rootstock. The seeds are larger than jak and quite vigorous. Champedek seeds tend to be weak growers and problematic.

You are going to need more than the leaf to get a good id. There are lots of piper out there.

Besides zibethinis the most commercial would be graveleons but I feel that it doesnít generate the enthusiasm that zibethinis does even in the few areas where it is appreciated. Virtually nobody in Penang wants graveleons.
There are several other species that we are growing and graveleons and kutejensis are in production in CR.  Last year testaduriam flowered but didnít set on a friends farm here. 
I have heard of using graveleons as rootstock in Malaysia although I donít think itís common.  At Gary Zillís project here in CR they had zero success grafting zibethinis onto graveleons. Phytophtora seems to be a concern in Thailand where they use systemic fungicides to avoid it.  We havenít seen a problem with root fungus on durians here so far.  Root fungus is around as we have plenty of trouble with avocados and black pepper but so far I havenít seen a mature durian tree with a root fungus issue.

My inclination is to mulch normally. What is really doing this on my farm is nutmeg.

 Think thatís not unusual.

It hates dry.

Iíve been to Green acres twice, Eric is a great guy!  Itís one of the few organic farms on Penang. 
Are these photos current, do they have durian at this time?
I would like to be in Penang next June or so for durian and then go to Borneo for a wider range of fruits.

They can also be tied over at an almost horizontal angle, but once they start flowering they donít grow so much taller.

The seasons are a little crazy here. But champedek tends to produce along with lots of other fruits including durian and Marang. We have jackfruits that produce at distinct times from one another and thus, have jakfruit almost continuously where as champedek has a more confined season although it can easily come late or early, miss a season, but commonly produces twice a year here.
Right now we have durian, champedek, longan, achachariu, matisia, etc.

Anybody using Azomite?

Iíve never heard of it as a ground cover or combining with trees that you care about.  It is grown on fencing, trellising, or a fencepost tree pretty much the same as passion fruit.  But the fruits donít fall on their own like passion fruit so it needs to be low enough to pick the fruits as they turn black.  Itís a perennial that can begin flowering in 6 months from planting out.

How about blackberry jam fruit or lime berry?

The general rule for best development and then production of mangosteen is to grow them under removable shade until they reach about 2m. At that point the shade is removed, perhaps slowly.
Sure, garcinias including mangosteen will grow in the shade and they will grow taller and more spread out. Thatís typical of many other plants as well. More shade produces more and larger foliage.
But mangosteen eventually grown in full sun will produce more and be easier to harvest. When you see mangosteen farms in SE Asia they are always in full sun.

Costa Rica  looks small on a map but has quite a variety of climate zones from lowland up to more than 8000í.
At our farm we are starting durian right now and there will be two peaks in September and October. Thereís a lot of fruits that go along with that like champedek, Marang, garcinias like cherapu and Brunei cherry. Thereís plenty of native fruits as well.
To know for sure about next April or so it would take checking back by December so we know what the corresponding flowering season has been like.
There are many places to look for fruits here. The Thursday farmers market in San Isidro, General has rare fruits from all over CR and there are many colder weather fruits there like Cherimoya, tree tomato, etc. I frequently find fruits there that Iíve never seen before and I have a collection of more than 200 kinds and have been exposed to many more.
Costa Rica has a very good farmers market system all over the country. The Tico is a good fruit customer so fruit stands and markets are well supported.

Sapodilla grows tall in the tropics. Seven years old could be easily 30í and on the way up if you donít shape it.

I get that it is a cool thing to have a mangosteen tree in a 15 gallon pot with 20 fruit on it!
I used a cleft graft on an area of wood becoming green perhaps 5/16 thick or so. I wrapped everything with parafilm.
What makes this expensive is that the rootstock needs to be about 2 years old.  With mangosteen I only have experience grafting it onto the same species but I imagine it should be easy enough on another Asian garcinia. I have even grafted garcinia with different color saps successfully. I feel itís an easier graft than pouterias, artocarpus, and durios which are other stuff I am grafting commercially.

Grafted mangosteen tends to lean over, never growing properly upright.  They look floppy. You see them staked.
So youíll hear that is because the scion was a branch tip and grows sideways accordingly. Well, there are only so many tree tips to use but on a large mangosteen tree you can find vertical growing branchlets and those are supposed to be ok. 
Iíve used the vertical branchlets and the result was the same.  On another garcinia species, g. parvafolia I did take an actual tree tip for a graft and I experienced the same problem.  Some garcinias can be grafted fine but for me neither mangosteen, cherapu, or Brunei cherry is worth grafting. 
This sentiment about avoiding grafting for planting out mangosteen commercially is common among those familiar with the results.

I grow mangosteen commercially.  We harvested 1500kg at our last harvest.  I also have a fruit tree nursery and used to graft mangosteen.  Theyíre easy to graft as are many garcinias, but I try to talk people out of using grafted mangosteen.
Iíve tried scions from different parts of the trees but the result has always been the same.  They do produce faster but fail to develop a good shape and so for a farm I think seedlings is the only way to go.

In My part of Costa Rica we are in a good fruit phase right now through October. The next season would be around April or so.

Sounds like good conditions. Not too sure about the Daintree getting almost 4m by now!  Thatís kind of extreme, hope that doesnít happen here.
Our rainfall ranges from 2m-5.5m but averages more like 3.5 probably.
