Sorry No Idea usually Paw Paws are so easy to grow with not many problems.
But it could be bad drainage or Acid soils or any of the things in the Link below.
You may find your answer there. Cheers...MM.

Here is a link that might be useful: Paw Paws in the home garden

That's root rot, it happens whenever you try to grow tropical Papaya in a cold climate or in soggy and cold ground over Winter, you get the same effect from frost but on the top half of the plant. I still think that Queenslanders should start calling them the proper name Papaya instead of Pawpaw because I got a bit excited that you were growing Pawpaw when I saw this thread : ) it would be less confusing then

Seems there a lot more than just QUEENSLANDERS
that call Papaya ( Paw Paw common name in Australia )

And how anyone can get excited over a Asimina triloba
that tastes like a banana ( Paw Paw common name in USA )...MM

exactly misty morn,

i've also seen those gardeners in southern USA calling the yellow paw paw a paw paw, for me it's been called a paw paw all my life on this planet.

the problem menioned here does sound like a drainage or lack of sun problem? me no expert but i have fruit bearing trees in sandy loam full sun in a frost zone, yep got frost damage but they are still growing & fruiting.

Nicefrog is right, Papaya and Paw Paw are two completely different fruits. Papaya tastes like vurp!!!

Well I certainly agree with you wicky on the taste of Carica papaya ( Common name Paw Paw in Australia )

What nicefrog wrote was:

He no doubt is talking about Asimina triloba ( Common name Paw Paw in USA.)

When in actual fact there is no such fruit as a Paw Paw.
It is just a Common name for two different fruits in two different Countries in the World.

I do not see Apples with Malus signs near them, or Oranges with Citrus, and what about Apricots they are Prunus. We dont seem to call plants or fruit by their Botanical names we use Common names.

In the Original thread up the top it was written by a Queenslander as that is what they are called here Paw Paws
Cheers...MM

I'll allways be anti Pawpaw name for Papaya :D, It's Papaya everywhere I've been, it's even called Papaya in the supermarkets in Victoria, It's called Carica papaya and besides Pawpaw (Asimina)is just as good or a better fruit than Papaya. Perhaps calling a Papaya Pawpaw is stoping more people learning about Asimina and realising how much potential it has

Mistymorn, We DO use the common name because that is the COMMON reference for plants. Plants aren't often discussed using their botanical name unless distinguishing between plants to avoid CONFUSION. It would be unnecessarily confusing to refer to Pawpaw (Asiminia) and Papaya (Carica) both as Pawpaws.
Just because some people call the Papaya a Pawpaw does not mean it is correct or common.
The name, also spelled paw paw, paw-paw, and papaw, probably derives from the Spanish papaya, perhaps due to the superficial similarity of their fruit.
It is like calling an alligator a crocodile just because it is in the same family, Crocodylidae, and looks similar.
Google Pawpaw and see how many references to Papaya you get.
*Quickly googles Pawpaw and its derivatives to check*
As I said, I agree with Nicefrog...Goodfrog
You don't have any Pawpaw seeds do you Jason?, How about Capulins....:)
P.S Not Vurp seeds...(Vurp not common name)

heavens to bettsy or is it murgatriode? lol hey when in qld do as the romans do is that the saying hey lol??? next thing you'll have us calling qld blues/butternuts/japs/and jarrahdales winter squash or something huh lol??

we are all gardeners of the! can i say it simple type we are not high fangled horticulturists, so common names that we are borne and bred with are the ones we use. papaya/paw paw all the same thing with reds and yellows, yellow being the most common sort in australia well this end of australia that is.

Yeah!!!, Who really cares?. It is funny what people call things, Poms call all vacuum cleaners Hoovers:)
*Thinking of a few choice names*

Yeah, just like Aussies call permanent markers Textas, and old people call nail polish Cutex and others call correction fluid Liquid Paper or Tippex.
I recall hearing of a clash of cultures back in the early 60's between two colleagues - one Australian, the other English. The English man asked the naive 16yr old for the Durex. The English term for sticky tape but the Aussie term for condoms! In her late 50's she still blushes when telling the story.

textas?? i call 'em felt pens or marker pens mmm chuckle just gotta be liquid paper or white-out hey?

oh well i'm a qlder i'm allowed hey lol??

len

Hahahaha!!!!!!!!! Aren't you all very funny, I start with asking about a PawPaw, Papaya, or whatever one may call it, and I end with a vaccum cleaners, felt pens, condoms, etc. etc....... :-) But thanks anyway to all of you for the good advice!!!!!

Wicky of the desert, I have Capulin seedLINGS but I don't think I have anymore useful seed if you want some, I'll post them over. Pawpaw seed (the real one) I found a guy that's hunting some out for me at the momemt in the wild stands in the States, but it's a couple of months away yet. The other day I got 6 species of giant Bamboo seed :d :p :D the good stuff, you know 70 feet tall, like in the Ninja movies where you can get in there with your sword and chop them down. I think they might be a good weed. Capulins are looking like being the best weed I ever found, I got somewhere around 100% germination on the fruit the birds ate and threw around my tree, impressive. I also have some weirder seeds of things, but I'll wait and see if I can get them to grow first. Wicky I am expert in memcal reprogramming these days (: nothing to do with plants but still.. I was bored in the Winter

Thanks Frog, Capulins are really hard to source around here. Perry's have seedlings but they are really expensive. My Durian bit the dust in its second winter.. Oh well get another one and try again with a slightly different approach. On off topic memcals, My cracked piston was combined with a twisted block, so it's now to be intercooled, blown and stroked:) Almonds are in full blossom, 29C on Thursday.

Wicky, have you tried using White reflective Panda? film, or Mylar film under some of your more super tropical trees?, maybe doubling the light is a bad thing especialy out there in the desert but it's worth a try. Didn't know about your broken motor :( oh well Peter Brock once said if you break it, build a stronger one

Well now elfi
If you end up with condoms you're obviously having much more fun than the rest of us. Jan

^ Hmm, interesting. I'd also read elsewhere that they grew well right on a riverbank or in a wetland strip by a pond. So, now I'm confused?

They (Asimina triloba!) like moist soil but not wet soil. What is the difference? In moist soil, there is enough water that you can detect its presence by rubbing the soil together between your fingers: it doesn't break up like a dry powder. But there is little enough water, that air can regularly penetrate easily all the way down into the soil -- there is no zone of standing water (the water table is well below). In wet soil, there is enough water that the air exchange is limited. This may be due to capillary action from a lower water pool, or to continuous supply from above. You may even be able to press water out, given sufficient direct pressure. These two types of soil will likely smell different (the wet soil is anaerobic, generates methane and gaseous sulfides), as they host different populations of bacteria and fungi, even if they had the same original composition. Some plants tolerate low-oxygen soil (sweetgum, sycamore), and some do not (paw paw). Paw paw favors riverbanks not only because of the (at least intermittently) moist conditions, but because riverbanks tend to be deep fertile alluvial topsoil. To explore just a little deeper: many if not most plants require specific fungal partners (mycorrhizae) to assist their roots' nutrient gathering. If you don't provide proper conditions for those fungal hyphae to thrive, neither does the plant. The fungus is also symbiotically assisted by the roots, which leak a little sugar to feed them. In addition to the fungi, wet soil drives out earthworms, which otherwise increase soil fertility by recycling nutients. What can you do to alleviate wet soil? Reconfigure the soil into ridges with drainage swales between and redirect drainage from slopes and buildings. It's a delicate balance, since you don't want to run all your rain off into storm sewers!
