Tropical Fruit Discussion / Re: Your 2021 Rainfall totals
« on: January 02, 2022, 08:46:04 AM »
While we get a lot of rain we also get plenty of sun. Itís not unusual to get a good rainfall at night and then have a sunny day. Thatís the pattern we like but it can reverse easily enough. In rainy years our plants donít suffer, they tend to grow well. What can suffer is fruit production on certain trees like durian and mangosteen. Where I see plants suffer is in parts of CR that get a long dry season.

So, the year before was very dry for our climate coming in at 85Ē.
This last year almost doubled that amount with 160Ē
The drier year was much better for fruit production while more rain has favored planting and tree development. We have a pattern of two wet seasons and two dry so the yearly rainfall is fairly uniform in our corner of Costa Rica.

We often speak of the time you visited here. Youíre a star Luc.
Un gran saludo.

Metohuayo, if that is caryodendron orinocense, must be from Venezuela.  Orinocense would refer to the River Orinoco in Venezuela.

We have caryodendron orinocense.
Itís diocious and it hardly ever produces.  When it does itís really good.

Some other fast producers are Amazon tree grape and peanut butter tree.

Tropical Fruit Discussion / Re: Spanish Moss As Mulch?
« on: December 24, 2021, 08:49:55 AM »
Spanish moss is actually chains of small bromeliads.
Iíve heard it can be used as a medium for growing epiphytes.
Sure you can use it as mulch!

40 trees loaded with flowers, imagine the quantity of fruit to eat and sell.  Especially at the prices you get in Oz!

Thanks everyone for the encouragement, weíre having a great time.

Satya, I just responded to your message.

Tropical Fruit Discussion / Re: Best Options for Preserving Jackfruit
« on: December 16, 2021, 08:02:00 AM »
The cleaned jackfruit can be kept in the fridge for a week or so and still be very good. I agree that freezing jakfruit works well.
But what we mostly do is dehydrate it. Our best results come from very soft jackfruit. I sell the dried jakfruit at the farmers market, often chopped up with dried bananas mixed in. Lately, thatís been selling out every Saturday.

Itís common to use a bit of dish soap as an adherent to foliar sprays or alone to control aphids.

The soap we are using is powdered laundry detergent that we mix with water in a strong solution. My farm is certified organic and the inspectors say itís ok.
I heard of another solution from the Dominican Republic. Place about 4Ē of sand around the palm. When the picudo tries to dig then the hole keeps caving in!

We plant seedlings too.  Iím a great proponent of that.  One of our popular durians is an original seedling that we have named after our farm, ĎIslaí.  Gary Zill loves that durian and his guys sell it out of their nursery.
 Really, we need more locally developed durians.  Besides Isla there are a few others and we want to expand on that very much.  Most of the seedlings I have planted in the last 3 years are my favorites from Penang.  There you have some of the worlds best durians in farms with lots of local seedlings.  That seems to me a good prospect for great new material.
We take it kind of slow here.  In the last 3 years we have probably planted 30 durian trees, half of them seedlings.  Thatís a lot for my model but it could take ten years for the first ones to produce in commercial quantities.  Easy does itÖ

Called locally Ďpicudoí.
Keep it clean right around the trunk and routinely check for a hole that will be covered with fresh mud. They tunnel under the young palm, then come up, eating as they go, into the heart.
We pour soapy water in the hole and kill the picudo when it comes out. Sevin will work well if you use that sort of stuff.

Tropical Fruit Discussion / Durian planting ramping up in CR
« on: December 13, 2021, 07:37:53 PM »
We are currently in one of our two planting windows of the Costa Rican Caribe Sur.  At our Finca the planting is modest.  Currently weíre planting Musang King, 101, Golden Phoenix, Rainbow, graveleons, and a select Suluk.  This adds up to 14 grafted durians with the graveleons being a seedling.  So that itís not a mono crop weíve added in some grafted champedeks and jaks.
I say modest because our nursery has probably sold some 300 grafted durians this year.  Another nursery has sold way more and new offerings of grafted durians have appeared.  Two of my clients are planting with an eye on exporting to the US.  My personal model is to retail almost all the durian directly from my farm.
During the last season some people rented houses nearby to be able to eat durian every day.  Whole families drove for hours just to get here for durian.  Itís like gold fever, Golden Pillow!

Tropical Fruit Discussion / Re: canistel or lucuma as rootstock
« on: December 10, 2021, 07:42:33 PM »
Is there a way to tell the difference between small plants of lowland and highland lucuma, canistel, and Ross sapote?

I really like nice knives but most of my grafting is with soft, immature material.  My choice then has been surgical scalpels.  Not so sexy as the knives some are describing but pretty sharp.

In Mexico, people with limited resources have been known to fashion a grafting blade from an old hack saw.  Pretty hard material.

Tropical Fruit Discussion / Re: Avocado - burying the graft union
« on: December 03, 2021, 06:30:18 PM »
Basically yes. The first one I did was a low side veneer graft and I was able to bury it while still in the pot.
I first heard reference to this technique on this forum from a post by Mike T. Then I saw an article about it on an Australian rare fruits page.

Tropical Fruit Discussion / Re: Avocado - burying the graft union

Itís an interesting concept.  I havenít buried the graft Union with avocados but I have with other species.  With Mamey sapote I have had a very good experience.  It would be hard to root a cutting of Mamey but the scion started to make its own roots as well.  So, if there was a problem of incompatibility the scion would be able to survive on its own.

Congas are a serious problem for guanabana, citrus, etc.  Spread wet calcium carbonate on the wounds and see how it goes.

I would expect that the black stingless bee known locally as Ďcongaí could be the culprit.

Iím Costa Rica white sapote grows naturally at about 5000í. At lowland itís like trying to grow loquat or lychee. You might get some sometimes but doesnít really work.

Iíve had some very good white sapote here, better than what I had from the very dry Guanajuato.

In general, when grafting tropical species that are not the easiest, you want both the rootstock and the scion to be initiating strong growth stages.  We feel this growth spurt should carry the graft along with it.  So, we rule out dormancy.

Sergey, we air layer breadfruit easily but itís not the same with the other artocarpus.  We feel stuck with grafting for asexual propagation.

The issue of latex always comes up in these discussions.  I donít think it is the problem.  As Ben said there is no dormant period in the tropics.  The latex can be ignored or you can wipe or wash it away.

As with the durian I am grafting on very young material. Both the rootstock and the scion are very tender. Mostly I use grafting clips as the very green material can get damaged or pulled this way and that while wrapping conventionaly.
