Problem with Paw Paw tree, leaves dying (forum)

Lorraine starts with ...
Hi, we have a very large bi-sexual paw paw tree that is nearly two years old. It has yielded us some fruit, but now the leaves are all dying.

Can anyone give us some clues as to what it could be?

We have checked the PH levels and all OK.

More information required Lorraine
Are the leaves dying from the bottom up or from the top down? A photo would also be good'

Leaves dying from the bottom up could be lack of calcium, from the top down could be die-back = bad news.

Good Morning. I have a problem with my pawpaws. As you can see by the pics that the leaves are curling up and I get a black spot on the fruit. After the frurit is picked and furthr allowed to rippen they look s if they have a cancer. What is wrong,, I have sprayed then with copper oxychloride from advise I got from Bunnings.

Cheers Robert

Hello Robert

Looks like a severe Calcium and Magnesium deficiency to me. Make the ground white under the canopy with Dolomite and spread Magnesium sulphate over that again then scratch it in. I trust you used a wetting agent with the spray, it won't work without it.

As you pick the fruit, just as it starts to colour wipe it with a darkish pink solution of Potassium Permanganate [Condies crystals] to help stop that fungus. You can get it from a chemist

I think that will work for you
Cheers
