That sounds like cold damage to me. Proper irrigation is a must. High relative humidity is not a must for breadnut (i.e. no brown tip or edges) under shade.

Hi Patusho, It might be cold damage on the older one (even though I brought it indoors on cool nights), but the young tree was grown in an enclosed, humid greenhouse, and has only begun its decline after I got it. It has not been exposed to any cold.

I had read that Breadfruit trees here die from dehydration. So to me, that means they require lots of moisture. Am I wrong?

Do they need shade? Maybe it is sunburn on the leaf edges? But the smaller tree is under shade, although it gets bright light (it is in the screened entrance to the house).

Some of the new growth on the trunk looks blackened/burned. I have been very careful with fertilizer, using fish emulsion and compost only. Last year the bigger tree did very well.

The pedalai still getting crinkled and distorted leaves and the low is already 20ºC!!!

You´re right Lisa, I initially thought they would stand some drought (and direct sun for 2-3 hr at the same time), how wrong was I, the talles one (1.5m aprox) shed all its leaves almost inmeadiatly and would have die if I hadn´t notice it.

If well watered they can stand (just) some direct sun even in here (or partially shaded)

All my breadnut lost about 90% of theirs leaves this winter, no stem rottening though.
