Foto taken today of the herrania I mentioned that flowered for years before it finally started to set fruit.

I grow several species of Herrania and cross pollination helps for sure.  But I have had a Herrania flower for years and never set and now it does set soÖ.it might be ten years old and 12í tall.

I think that if it was up to people like us then we would be always looking for new varieties to plant.  I think that it is the buyers that donít want the complication of lots of varieties so the producers plant whatís known and easiest to sell.
On a small scale it makes sense to have new varieties to share with clients who appreciate diversity so thatís our focus.  But I donít know how many varieties of durian a packing house wants to buy.  Maybe only oneÖ

Interesting Arvind.  What is your distribution like?
I think that ideal here is 2500mm with two short dry seasons in March and September.  And we get something like that sometimes.  The ground doesnít completely dry out but dry enough to induce flowering for two harvests a year!
When it is prolonged dry with lots of sun the temperature goes up to about 33-34C.  A friend to the north in Guatemala got overly dry weather this year with temps to 40.  They lost the durian fruit set and some established trees even died.

We are just starting to get some early durian drop this past week, so pretty exciting.  This, right now, is from some very early flowering and weíre expecting our peak harvest of durian and mangosteen in September.

Costa Rica. Weíre going to have a great season starting next month with durian and mangosteen topping the list.

I would add acerola to the list.

Looks good, but I donít know why anyone would have trouble germinating rollinia.  Biriba is a weed that is invasive on our farm!

I only use a grafting knife on very hard wood but mostly I am grafting green wood and my preferred cutting tool is a surgical scalpel that I buy on Amazon.
I use grafting rubber band wraps and parafilm.
The cutting and wrapping technique and the idea to use the scalpel I got from Gary Zill.

In production areas of CR, like our farm for instance, durians are selling for about $8-$12US per kg.  Maybe $6 for kompong and the higher price for musang king which has very limited availability.  Thereís a lot more D-99 around than musang king, Mongthong, etc.
There has been some durian in Perez Zeledon and that shoul happen until August and then September into October on the Caribbean coast.

Would be interesting to try them all.many of the best durians have been discovered from plots like that. Perhaps thereís a new rival to Red Prawn among those old trees!

We spread seaweed under our trees sometimes and it breaks down alright. It can certainly be composted and microorganisms should help with any odor problem. I think itís a good idea and itís likely you can get a lot more minerals besides the potassium that you expect.

Tropical Fruit Discussion / Re: Yellow sap in mangosteen
« on: June 20, 2024, 06:19:57 PM »
Hi Ben
So I would apply calcium carbonate or dolomite in a wide band on both sides of the drip line at least twice a year. 500 grams per square meter. When fruit sets apply calcium with boron foliar spray every two weeks.
It would be nice to have a soil test to work with and to be doing leaf analysis to see if the trees are really absorbing the calcium and then see how it effects fruit quality.
Suerte!

If you want stuff like Marang, champedek, pedalai, langsat, etc. you need to coordinate the time of your visit accordingly. The Caribe Sur can have two seasons. One falls around March/April and the other August/october. The southern Pacific coast has a single season that is like July/august. Those are the areas that have the most rare fruits.
But there is always something.

Did you get to taste the plinia costarricense?

I was having this problem with a few of my mangosteen trees and others were consistently good. I obtained the information I shared from an Australian research paper. So I did leaf analysis of some trees that had problems and others that were always good. Sure enough, everything was pretty much identical except for calcium!

As the fruit develops, if there is a lack of calcium or too much water then the husk doesnít keep up with the devopment of the pulp. The pulp gets squeezed andÖ Another problem besides the sap is that the pulp gets translucent and hard. Also a calcium deficiency.
Splitting jakfruits is basically the same issue.

Sabah has more than one season. It was good for us in August. Both around Tenom and towards Brunei from there. Also near Kinabalu. Lots of Durio species both areas.
Thereís a guy Maryoto who I have never met but has a good reputation.

Tropical Fruit Discussion / Re: First time trying cherapu
« on: June 16, 2024, 01:17:00 PM »
Planting seedlings seems to result in a lot of males.  Iíve topworked females onto the males but that has resulted in poor shape typical of mangosteen grafts.
While in Malaysia last year we came upon an enormous cherapu coated with fruit that seemed to have no male around.  Quality was very good and Iím planning to plant those out soon in a site with light shade like the one that we collected seed from that was among durians and some native forest trees.

Lowianus is a good durian that we ate south of KL and again in Sabah.  I think that there are a lot of durio species that are considered inedible. Perhaps itís undescribed.

I have a seedling tree over 30 years old that can produce over 300 fruits in a season.  We call it ĎIslaí nameing it after our farm. Itís good and we sell the fruit.  Kind of vanilla cookie dough that is a good introduction durian.  I encourage planting seedling if you have lots of space and weíve planted quite a few.  But it could be that our kradom/D99 that are 25 years old produce just as much durian by weight, has more flesh, than the Isla.
Somebody asked me about getting red prawn for here but I keep hearing that it has inconsistent production.  Iím a little concerned about Black thorn on that account as well but I have 4 of them planted.

In fact, to grow from seed would take a laboratory.

I like mulching durians and applying microorganisms on the mulch. That seems to keep the root diseases away.

Vanilla is planted as cuttings to grow on a post. We use living fence post material, like glircydia   Cuttings should be a meter long and are wrapped around the base of the post and the top end is tied at the bottom. You put lots of mulch on the vanilla. Here, vanilla cuttings cost $2-3 per cutting.
Suerte!

Yes, Puerto Viejo. We are still dry here which is very unusual. We get some very light rain but the soil is very dry if you dig a hole. July is just around the corner and it has always rained so weíve planted anyway and are watering. Fruit is developing and thereís water in the wellÖ

Sure, itís a good question. Thereís some evidence that durian appreciates being in kind of a forest area. While in SE Asia I have seen lots of glyrcidia which is an Americas nitrogen fixer. I donít know about inga there but it can probably be found.
When you are planting small durian trees at around 8-10m spacing it leaves a lot of space to intercrop other stuff or to fill with nitrogen fixing plants for chop and drop.
