JACK FRUIT TREE

BJ says...
Hi Letha, Gold Nugget is the one that is described as a dwarf Jak, but I've heard it still can get to 6m odd. There are anumber that you can prune and maintain under 15ft, and some that folks will tell you can be kept to 8ft !?

There is a good bit of information on various varieties an a PDF on this page:

http://edis.ifas.ufl.edu/mg370

And this info may help with pruning:
Pruning

Young trees. Young jackfruit trees do not need pruning during their first year. Shoot tip pruning once or twice during spring and summer will force lateral bud break and make the tree more compact. Non-pruned trees usually develop a strong central leader. During the second season, trees should be pruned to the first lateral branch, which will slow upward growth and enhance spreading of the canopy. As trees mature, upright vigorous shoots should be removed and the inner canopy thinned out at the end of the harvest season.

Mature trees. Removal of selected upright, vigorously growing shoots is recommended. Removing the central leader to a weak lateral branch will slow upward growth and enhance lateral canopy development. Old flowering shoots should be removed after harvest.

For bearing trees, periodically remove (thin out) old limbs at the end of the harvest season to increase light penetration to the inner canopy. Tree height may be maintained at 8 to 14 feet by periodic selective pruning. Selective pruning may also be used to limit tree width.

Fruit thinning. The number of fruit per tree or major limb should be limited to 1 on young trees, as heavy fruit loads have been observed to result in limb decline or death and tree stunting. On mature trees, limiting the number of fruit per major limb may enhance the quality and size of remaining fruit.

Hi Letha,

You are pushing the climatic range with the jakfruit in Sydney. It will certainly grow but whether the fruit will ripen properly is another thing.

I have a 'black gold' jakfruit growing very well in Wollongong. Hasnt fruited yet but im happy with the tree so far. They shouldn't get too tall in Sydney compare to the tropics - perhaps 6m in 20 years time. You can always prune it.

No, not fatal as most jaks are either 26 or 28 Kg.

Tommoz says...
Thanks BJ.

I am still hoping someone knows of any place I can buy fresh jackfruit in Sydney.

A guy said that the Juicy fruit gum flavour is from jackfruit, but I want to taste the real thing!

Tommoz says...
I really like the taste of jackfruit and am thinking of doing the unthinkable: putting one in my front yard albeit on the side and well concealed.

What are the roots like? It will be near driveway.

Daleys only have 2 available: Brindsmead Special and Crisp seedling. FF has Crisp and Kwai Muk. Are any of these preferable for outer Sydney's climate?

If tree shape can vary, I'd prefer a more upright one, like in this picture: http://upload.wikimedia.org/wikipedia/commons/2/24/Jackfruit_in_tree.jpg

Kam - what variety jackfruit gave you even those fruit - at least its flowering there on a similar latitude to Sydney - well done :)

Markmelb says...
Waterfall - I would love to know what your is also - is it grafted and what variety or is it a seedling or an unknown cutting like mine - trying to work out what would be the most cool hardy one for Melb - Thanks

The poster formerly known as... says...
Hi Waterfall, so they had a grafted advanced jackfruit at the nursery?

Markmelb says...
Waterfall - do you thinks Brinsmead may do better in cooler climes due to latex free nature - I thinks so as latex cambium could be very temperature sensitive comared to no latex cambium -love to see so evidence of that thought???

Markmelb says...
I checked before and the grafted Jacks are only $39

Kam says...
Hi Markmelb and Waterfall
My Jackfruit tree is an Artocarpus Heterophyllus and it says in the tag that it bears fruits from 3 to 8 years. It had not done well for the first 3 years because the hot sun in the summer in Perth just burnt the leaves and the new shoots. Last year I decided to try to erect a shedcloth over it. New shoots and leaves appeared. I have taken the shed off and the leaves are not looking too glossy. Shall I put the shed back on for the summer? I think I have to wait for next year to get some fruits. Last year I had 2 small fruits but they dropped when they were small.

I am wondering if someone can tell me whether a Shahtoot mulberry tree will grow into a large tree. I have recently bought a Shahtoot tree. Removed some buds from there and budded on to black mulberry cuttings in pots. I had 2 out of 4 and quite happy about it. Someone can tell me whether they are right for each other? I have a feeling that the black mulberry tree will be too vigorous for the Shahtoot?

Waterfall says...
I have shade cloth over my avocado so that it goes under the shade at 12pm. The other day it was 38 degrees at my place and part of the avocado was slightly exposed which had new leaves literally melted. I have since moved both my jackfruit trees under the shade cloth.

I have a few other tropicals which don't seem to mind the sun like rollinia, panama berry and my 3 mango trees.

Hi Mark
I forgot the pictures earlier.

You can choose between crisp ones and soft moist ones. There is also one that is latex free which means the sticky white sap in the rind is not a problem. They can get to a very big tree, or some are smaller trees. You can keep them small by growing it in the confines of barrel or etc. Or encourage it to grow big and get piles of fruit to freeze for later.

Markmelb says...
My Brindsmeade is handling the cool temps ok so far (supposed to be Latex free)

I got it basically because Daleys showed it handled frost from a video on its page and it doesnt get frost where it is (see my edibles)

- also find youself an Asian Grocery and get a big can of green jackfuit and make a Sri Lankan Jackfruit curry - Very yummy - good use for your curry leaves also - many recipes for it on the web.

Markmelb says...
I thought that too - BUT - How long have I got? Love to be the first to grow a Jackfruit unheated in Melb?
I have pics on my edibles of a 4 year old un named cutting that has Latex and is inside now till November as it didnt like 8c and started to die back in its first winter - now has lots of new growth but maybe flowers this year.
Ive seen them in Bali and they can fruit quite small but can also get very big too.
Brinsmead comes up fairly often and is a smaller tree as you can see in Video.

Markmelb says...
Bangkok - can you put up some photos of your top working - we dont have those varieties you have here - in fact any imported Jackfruit never has their name on the box they come in - not good marketing as we would like to know :)

Markmelb says...
Hi Bangkok - would still be nice to see a few photos of your Jack trees => where the grafts are? - size and shape?
Im finding here in Melbourne alot of Thai plants are very cold tolerant - even small round Thai eggplants can survive winter and the Nam Doc Mai mango also grows well for me - see my edibles page - In fact start adding photos to your page makes is much more interestng for everyone on this Forum to see what results are acheived beyond the seedling purchase :)

MIke T1 says...
It is the same Bangkok.

sternus1 says...
Yeah I figure as much too. Oh well. It's time I started paying for a VPN anyway. Did you actually get banned or did you just stop posting?

Bangkok says...
Well i just got a ban but it's not public. Members still PM me and i can read that but can't reply. I can also still change the pic and text.

But why you guys need a VPN? https://hide.me/en/proxy

But Jackfruit can start fruiting pretty small and in a container of 50-100 litre. I've seen them for sale many times with fruit.

My tree is about 4-5 metres and still didn't fruit yet. I prune it sometimes to get a nice shape.

Bangkok says...
Yup mahachanok comes from Thailand but they want to sell it as "the new variety from Florida" haha. Doesn't that say it all? And they even put that on their leafylife website!

And on top of that i still doubt if they have the real mahachanok or just a seedling of it.
Some of their mahachanoks don't smell very strong, then it's not the same as we have in Thailand which has a very strong scent.

My thai family have a huge old mahachanok in their garden. I didn't know that for more then 10 years because they never told me about it and even my wife didn't know that. That's how special that mango is to them.

The main thing i learned from TFF is that the Springer show wasn't made with actors like we always thought here on this side of the ocean.

anusha says...
how about the area that is pruned, should we cover it or will there be any decay if left opened.

Jose Luis says...
We live in Sydney and have a jackfruit tree. I do not know the variety but told it produces crunchy fruit rather than the soft variety. Unfortunately our tree does produce fruit each year but when winter comes along we get rot that sets in from the top of the fruit. We had about six large fruit that suffered the same fate last winter with the largest the size of a basketball albeit not round. It would have been at least 4 kilos. The tree is about 10-12 years old and about 3-4 metres tall.

Jose Luis says...
Waterfall....where in Sydney are you.
We are at Dundas.
Do any of your fruit reach maturity?
Our get rather large just before winter and then develop rot right at the top of the fruit.
Our tree is rather large and is developing fruit at the moment.

ivepeters says...
Glad for you, the start of the payoff after so much time and effort.

Bangkok says...
Did they already smell when you picked them?

Mine don't smell yet and are still pretty hard so i don't dare to pick them.

Yours still has the spines, mine have smoothened spines now...it's one of the signs to know if they are ripe i read.

On the market i see them having brown/black spots before they are being peeled/sold. Do we have to wait untill that happens or did they let them get brown after picking?

The shop with the brown ones has the best jackfruit of Bangkok, they taste much better than from other vendors. I still don't know what their trick is but i grow the same variety so i guess mine also need big brown spots before i open them.

Colinas says...
On Saturday, we found the first edible jackfruit from our five-year-old tree. It had fallen from the tree, and had two possum divots, but when cut open, it was sunshine-yellow, ripe and delicious.

Last year, we had many fruit on the tree, but these failed to ripen for a number of reasons.

And we were told that you cannot grow jackfruit in Sydney!

You read about it on our blog

It is normal for the first time of flowering that the flowers are probably male and fall off.

Colinas says...
Hi Markmelb

I thought my mangoes ripened late in the season. Yours are very late. Congratulations on your achievement so far south! When you get them, you will appreciate them, because there are none in the shops!

When your mangoes start to colour, pick them and place them in your rice container, if you have one. We have a rather large rice container in the kitchen: the rice helps to ripen the fruit, according to my partner.

My two jackfruit trees are seedlings, fruit purchased in Cabramatta, and are different varieties, judging by the flowering times.

One of my children, IT-employed, helped me to establish the blog. It includes tale from our Malaysia travels, gardening experiences and the occasional home-cook recipe. It is open to the public.

Thank you for your encouraging comments...

Blackgold says...
Hi Rich
Just saw your old post in Daleys forum.
I see you have a Blackgold planted in Wollongong.
May I ask how the tree is growing and has it had fruit yet?

I'm also after a Blackgold but Daley does not sell them at the moment as they can't source graft wood.
Hope to hear from you.

Regards
Roger Ning

Blackgold says...
Hi Rich
I don't know how to tell them apart.
Did you have 2 different varieties of Jack fruit seeds?or are the seeds from the same tree.
Are the seeds from your Blackgold tree?
I have bought 2 grafted jakfruit trees from Daleys..Yullatan which are suppositly cold tolerant.

I'm growing seeds as rootstock to try and graft the 2 varieties.
How big is your tree now?
Cheers for now.
Roger
