Cempedak cold tolerance
« on: June 26, 2017, 09:25:45 PM »
Hi all

Been reading for a few years but only just joined. Figured I would ask a question I have wondered about for some time. Does anybody know if you can grow cempedak in the subtropics? I am in Brisbane Australia and my property is frost free though does get down to 3-5 degrees Celsius during early mid winter mornings (rarely).

It's a tree I have always wanted to grow but wasn't sure if I could.

Thank you

Dan

Posting back in case someone searches the topic. So after speaking to someone who is very familiar with chemps it seems the lower limit is about 1 degree Celsius. The lowest here is about 3 (and not every year) so I'm hopeful and I'm going to give it a go. I was also told that it does vary between varieties so if I can will try a few. I'll post back with my experiences.

Thanks for the feedback Ulfr!!
Do you know if that is for young trees? Could a large thick trunked tree maybe manage a degree or two colder?

About 0c for bigger trees and 1 to 2c for younger trees and small seedlings are more sensitive again. Brisbane in Australia is about the southern limit here.It is a bit more complicated that straight numbers however with length of time at low temps and wind to be considered. I understand that different varieties have different tolerances as well.

How did the Chempedak go in Brissy?

It could depend on specific areas and microclimates and site aspect, possibly on the coast it is milder than in the hills.
They may even go ok a bit south in subtropical NSW.

I will add that chempedak seedlings also can just randomly die. I had one the growing well from months and then just died. Sounds like that is reasonably common, can't imagine cold weather would help either. I wonder whether chempedak grafted onto jackfruit would improve cold tolerance.

I had a Cempedak seedling slowly die on me even though it made it through one winter. I have another Cempejack seedling that has made it 2 winters and even came through in better condition than my grafted jackfruit but it is a much slower grower and only wakes up once the night time temps are in the 70s and lots of rain. I would agree that the Cempedak has a much less vigorous root system and grafting into jackfruit would be the trick.
