There is no a. hirsutus in Thailand, but they do have a. rigidus as a native tree.  It's a closer photo much, just not polinated very well perhaps.

These are what happened to my Marang seedling:






Any idea what could cause this? I have them under grow light occasionally get late afternoon sun from window. These were in the garage around 75-80F in South Florida winter (not humid). The photos were taken in December, they all are dead now.

I read this all the time: " I gave them warmth, humidity, artificial light and they still died". First of of all most trees aren't your tomato plants. They have far more adcanced features how they able to sense and interact with surrounding environment. Many cool studies and experiments in this field. They have grearter need for real sunlight rather than tomato for example. Artificial light probably has one type of infra-red out of three, maybe few other wavelengths. There is a whole spectrum of ligh missing or gets filtered by a glass.
Another example, I could probably thrive and survive for a while in underground bunker with plastic food and a tanning bed to compensate sun. But eventually I will start to deteriorate
longing for real sun on my face and feeling of wind in my hair like I'm genetically accustomed. 

The problem with all those bonsai, pruning, and grafting ideas that this particular species grows in usual fashion like a palm. My tree looks like a tall branchless palm now. All the growth happens from tip of the tree, any branches near the top fall off quickly as the tree grows.  I have strong suspicion if you cut the top, the tree will likely die. But never done such experiment. There is just one picture on the internet of young trees, you can sort get an idea how challenging pruning or topworking is going to be. This tree simply want to grow like a palm during first several years.
Regarding 4 years from seeds, these particular info comes from Malaysian publication describing growth of grafted cultivars. Looks like it has been later copy and pasted all over the internet as a fact. But in reality people attempting to grow this species report much longer time. This particular Sarawak native women says it took 10 years for the first flowers to appear.

Part two of the update. Marangs. This is most promising species. Nearly all marangs I got made them bushy with lost of low spreading branches and no clear leader.  After seeing how well it reacts to size control, I think it's borderline sinful act just to plant and do nothing about size control  .

This is the only tree from from the first post.  Reuploading first pic to follow progress. The earlier pic is after second toping at 9 feet and the tree now.





Marang nr. 2. Topped higher than I usually do at around 7 feet and additional toppings of the leaders.



Marang nr. 3.  Topped at maybe 4 feet, than additional toppings of 3 leaders, now about 10 feet tall.

Any updates to the trees described in this post?

Some updates on artocarpus pruning techniques.  This is my last post. I'm done with pruning and topping. Trees are too big now to control them.

My method is pretty simple.  Cut the leader at about 5-6 feet. One usually get's leader to split into 2 or 3 branches, let them grow 3-4 feet and top all the leaders again. That's about it. Very simple. Works for nearly all artocarpus species. This technique is especially awesome on marang.

First of all on which species my method does not work. That would be chempedak and jackfruit. Looks like for these two are very much dependant on a variety, particular seedling, whether grafted or not, etc.  However what does really work well for chempedak size control is budding ( not grafting) on jackfruit. Those trees don't even look like trees. They grow like bushes. Here is a pic of example:



Pedalai. This tree was topped countless times.  I was determined to tame this giant.  I think all the topping let to the sprout and growth of the second trunk, which also has been topped. I even got third trunk to sprout, you can see. But I got greedy, wanted to split super low, and the tree simple abandoned that brach. Despite all efforts tree has intimidating size. I think most fruits will be unreachable anyway if it ever fruits.



Artocarpus hirsutus.  This tree was topped maybe 3 times. Also the side leaders got haircuts during second on third time. I only seen big trees, never seen young trees, so not sure if my method worked on this species or not. Maybe young seedlings looks naturally this way?  Mature trees if seen hardly have any low branches.  Can somebody from Kerala comment on a photo? Vipin?



Unidentified artocarpus. Since we here maybe somebody can ID? I'm pretty sure it's keledang. Usually don't plant without id, but this one planted anyway. If this is indeed keledang than it's great looking bushy tree without clear central leader using technique described above. I've seen mature tree in rainforest environment and fruits are basically unreachable. 



I'll update on  marangs later, when have more time.

Edit. Not available anymore

This is wholesale offer only.  Have remaining seeds, don't have time for small orders or USDA paperwork. Make reasonable offer and take everything. EMS only. 18 Musang King seeds and 7 "Ice Cream" also called "Kuching Tidur", translates sleeping cat.  Legitimate five star variety.  Apparently even Lindsey never came across this one. See comments sections:

In Malaysia all durian sellers use butcher style knifes, something like picture below. These knifes makes easy to split durian rinds once knife inserted into fruit. There are foldable versions of this style.

The pulusan though is a real tropical, right? I mean, in a subtropical climate we just have one option to pick from these 3 species: lychee. Or it would be a realistic bet to expect a crop from pulusan or rambutan trees in a 11a or colder region?

Yes pulasan is an ultra tropical. The rambutan is also tropical, but it seems more widely adapted than pulasan. So you would probably be able to grow it and fruit if you give it some special protection in winter. Lychee is subtropical, so should be easy for your area.

There were only one or two successful rambutan fruitings in S. FL after enormous efforts to keep them alive, even though S. FL has nearly everything going for it: borderline tropical climate, sufficient humidity etc.  Southern Spain is much cooler and drier, no matter what microclimate Jose is in. It's subtropical/ mediterranean climate.  Rambutan maybe alive for a while but will be absolutely miserable. I feel sorry when people given false hope. There is good reason 2-3 years on they never update on their little pet projects.

No, Southern Florida does not have everything going for it for growing rambutans. The problem with Florida and rambutans is not the temperatures, but the soil. Rambutans will not grow in alkaline soils, and a lot of southern Florida is limestone. The people that fruited them trucked in soil from elsewhere. Also S. Florida gets occasional arctic blasts. Does Southern Spain also experience these? Anyway, note that i said he would need to protect them in winter. Humidity can be easily controlled by adding overhead misters.

http://tropicalfruitforum.com/index.php?topic=1249.0

I know about the soil. It's not just occasional cold blast it's persistent temps in 50's or 60's for days or even weeks in winter combined with arctic blast, which is far more stressful than occasional overnight dips in S. FL.  Southern Spain more or less = SoCal. Let somebody grow rambutan in the best of SoCal microclimate even with misters, and let's see how far that goes. This may sound new agey but seems like some species sense being on artificial life support and not happy about it at all, even though technically everything is provided.  There is quite a bit of scientific research into subject.

Those were Mexican imports by the truckload hence near wholesale price. Don't worry you have better quality in FL from homegrown garden. Quality, over quantity.

Credit this quote to a Sleepdoc that goes something like this: "Female flowers will appear and fruits will mature when trunk is about soda can thickness" That has been my experience too. Your tree is not there yet.

That looks like nice quality and size. I have few trees already, at this time just looking for good genetics. Can you tell about age of the tree, productivy, how old was the tree when started producing first?

I got a question for you guys. Given that shipping from USA can take up to 3 weeks and that Customs here is becoming more a more careful with vegetal stuff because of diseases like Xilella, purchasing scions is kind of a very risky bet for us. I've been said by another grower from Europe that rate of taking for imported scions from America is really low because of that. So I'm thinking now of another strategy to do it: Would be a safer, more successful way to get these new varieties, to bring fresh seeds of those that are poliembrionics? How long would a mango seed keep its germination capacity?

Why don't you pay for EMS?  About $45. I shipped mango scions from Florida to Phillipines and it took 5 days only.

Because of Customs, from USA to Spain EMS is 65€, if Customs agents see a small, very light packet and 65$ for shipping, they will most likely stop it and open it. That's the problem with scions.

Nothing is allowed technically, but I had a lot of EMS traffic seeds to US, few from from US,  quite a bit within SE Asia and nothing ever got confiscated. Sometimes you just have to be bold and count your lucky stars.
You could also send first to one of the relaxed EU countries up north if you have friends there and than forward within EU.  Those countries with relaxed customs and don't care about tropical stuff, it presents zero danger to them.
