Look's like my 2-foot tall plant is about to die, from root rot I think.
Probably because I watered it too much... 9L every evening. But the weather has been so hot and also it is on a raised mound.
Has some shade cloth above it.

They don't need a lot of water , actually they are very hard to kill , years ago I planted about 500 in a huge tub , left them under a longan and kinda ignored them . All grew well were transplanted and sold .
Don't forget that here in their natural habitat they don't get any rain for at least 8 months , just a little TLC will not hurt ...
