The Tropical Fruit Forum

I'm not sure about cold hardiness as I have mine in a greenhouse.  I remember that the excess jackfruit seedlings I left outside to die last winter lived through a couple freezes before succumbing.

The jackfruit trees (and other artocarpus) I had growing in containers seemed moderately healthy but sometimes struggled.   The ones I put in the ground in my greenhouse took off and are super healthy.  Might be my soil mix, or might be they don't do well in containers. 

In ground I have grafted "golden nugget" jackfruit that is constantly hitting the greenhouse ceiling ~12ft up and I have to prune it often, yet it still hasn't flowered yet.  Trunk is ~4in diameter.  I expected it would have flowered starting at least a year ago but who knows.  At this point I wonder if a seed grown one would have flowered already. 

It seems unlikely to me jackfruit could be grown in a reasonably sized container to fruiting size, but maybe there are some smaller types.


To actually answer your questions... I don't know what the isssue with transplanting them would be.  They seem fine up-potting and then going in ground.   They probably need up-potting twice yearly, I think the largest ones I have will be in ~15gal this year.  When in ground they seem to grow very fast, like 6ft in a year

Yes, check the soil and see if it is too dry or too wet. 

Note that when citrus is too dry, the leaves curl to show this.  Then, when you water it, all the curled leaves fall off (unless the whole plant is dead, then they stay on)

From the picture, your tree looks healthy otherwise.  It should sprout new leaves soon if the roots are happy

Getting some cool colors on new growth:

Yes!  it seems the new growth is a gradient of magenta to green, like the sheen of an oil spill.  Nothing like other artocarpus I have seen so far.

I had never heard of SugarBelle.  Looks to be a patented variety.  I'm also curious how it compares to Minneola.  "Very vigorous" isn't a good thing for me, though.   

Some of the best citrus I've had were Minneola tangelos (bought at the grocery store), however they are very inconsistent.  The ones I have grown myself so far have been soft and watery, and most of the store bought ones were same.  However, I am not giving up on them yet, I just grafted a Minneola onto flying dragon dwarfing rootstock as the nursery-bought one I had was far too vigorous.  I am going to give Minneola 3-4 years and see if I can get the amazing fruit I once tried, and if not I will probably ditch it. 

Yup!  I wouldn't rip up a perfectly good tree if you're happy with it, I just mean for anybody starting new Nordmann is the way to go.

here's example of zip tie + bag



this one the scion already had parafilm, but if it doesn't I don't bother adding it

my method is to use a few small zip ties to hold the graft union tight, then put a plastic baggie over the whole thing.  I don't use buddy tape/parafilm anymore. 

This method works for me because I struggle to get the film and other tape wrapped tightly, often I am grafting a bunch of branches onto one rootstock and there are thorns or other branches in the way that makes wrapping difficult.  I really like zip ties instead, they hold very tight.

There was recently some discussion in buy/sell/trade about lucuma rootstock options and from this thread it sounds like lucuma, canistel, mamey, ross all close enough to be graft compatible.  Good to hear, I had grafted some excess lucuma scion onto a ross sapote seedling, and I still have some more I might graft onto my canistel.

I planted mine in ground in my greenhouse to give it a try, fully expecting to cut it down if it isn't amazing.  I hear mixed things about it.  I've got other annonas, I will probably only keep one or two in the end.

Red lime has sour orange taste, it isn't anything like a typical lime.  It tastes like a rangpur&kumquat hybrid
