Paw Paw leaf concern

Hi Marcus,

I think the extreme hot and cold weather of Melbourne that makes some leaves like that. Apart from that your tree still look healthy to me. I would move the pot to an area with not too much afternoon Sun and see how you go.

Good luck and happy gardening.

I had a few different plants that the leaves turned white exactly the same as this picture. It only happened when they were moved from an indoor or covered environment to the open air.

I suspect where you got the plant from, grew it in a greenhouse or under shade cloth and then you put it outside when you got it. The leaves that were on it grew in different conditions - moisture and light - and sudden changes to these 2 things seem to have this effect on some of my plants too.

So it is not burnt by sun, but the leaves have never been exposed to direct sunlight and the white leaves sometimes deteriorate further, even if it is then kept in the shade.

However I have found that the new leaves that grow from now on, will not develop any white colouring.

I am growing red paw paws from seed in full sun, even on our hottest days, and there is no discolouration or burning of the leaves as they were grown from the start out in the open and did not need to adjust.
