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.

I would like to taste test the jackfruit but never see it at the markets in Sydney.

Also, isn't there the possibility that a 27kg jackfruit falling onto a head below could be fatal?

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

I dont know about fatal. By the time they drop they are usually pretty soft and would explode on impact. Could still knock folks out, but the trick is not to plant in a high foot traffic area and to keep your eye out for falling jaks. Around here a jak would be eaten by bats before it fell from the tree anyways. If you had a double row of giants lining a footpath it could be a problem, but otherwise you have about the same chances of a light aircraft falling on your noggin as you do being killed by a falling jakfruit.

Bunya nuts/cones are a much bigger concern due to size/density, tree height (velocity) and people's ability to get right up close to the trees in the drop zone.

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!

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

I live in Perth. My Jackfruit tree had 2 fruits but they had mould growing on them. They dropped off 2 weeks ago. Should I have sprayed the tree/fruits with antifungal chemical?. The tree may be about 5 years old.

I'm no expert but have a jackfruit here in Sydney so have done a bit of reading on them. I believe the first flowers will be male which usually develop this rot and fall off. Later you will get female flowers and these are the ones which will form large fruit.

Mark I actually have 2 jackfruit trees, both rather small at the moment.

The first was a seedling purchased off ebay at the end of winter, I did ask the seller if he knew the variety but he did not. It was cheap and I was not sure if it would grow so I didn't want to spend much money on it. When it arrived it was only 15cm tall with a few small leaves which all dropped off soon after. It is now about the same height but has grown lots of new leaves and looks healthy.

The second I actually purchased on impulse at the Daleys nursery whilst visiting Byron Bay for a mates wedding. It was a seedling in the bargain bin for $6 as it had a slight imperfection at the base of the main trunk. This one is about half a meter tall with lots of leaves, quiet a compact looking tree with lots of branches already. It dropped only a few leaves and looks a bit yellow now but I expect it to come good once it has acclimatised to our cooler climate than Kyogle.
I chatted to the guy working there as they had a grafted latex free tree there for $80 but he suggested I just try my luck with the $6 seedling.

Ultimately I will only keep one as space is at a premium but for now I am just leaving them in pots until I decide which one.

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???

I have no idea to be honest, my thoughts are that it would not be worth spending $80 on a grafted tree that may very well die in this climate.

I would think the best chance would be a very small seedling, get it used to the cold weather from a young age. Now is a good time to buy one as it gives them time to acclimatise before winter. That is my plan anyway.

Their advanced plants are $79, so an $80 jackfruit would be an advanced plant, I assume. They don't list all of their advanced plants on the website.

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?

Kam - that is just the Latin name on tag for Jackfruit -- so its either a seedling or a marcotted / air layered branch like mine - see if you have a graft just above soil?
The jacks dont like heat either like 35c plus so she shade will help mines partly under a shade sail but still gets hit by afternoon sun but I bring inside every winter next to my coffee plant and a west facing window and put back out at start of November - can you put up a photo to see what it looks like - heres a pic I just took of mine - it lost about 400mm winter of 2013 but is branching nicely and may even throw som fruit this year as is 3rd summer for it - will only get a grafted if I can get a better survival siuation or earlier fruiting -- Also try spraying Yates Droughtshield on leaves before you get hot weather - works on my Avocados a treat - cheers

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
Looks like I could have bought a seedling Jackfruit tree. I seem to remember I paid a fair bit for it. This means I have no idea what sort of Jacks I will be getting or if there is any. Some pictures of the tree. I put a broom there so you can see how tall it is. I put a lot of my pot plants under the tree for shelter when the shed cloth was up. Keeping the pot plants above ground prevent ants getting into them and stop my guinea pigs eating them.

Your Jackfruit tree looks good.
