I am located in Victoria, Australia and it has just turned spring. I transferred my very healthy ZZ into a new pot about 2 months ago and I realised I may have damaged some of the roots in the process, as some branches started wilting but some didn't. I cut off those yellowed branches. I let the plant sit for 1 month before watering it again thoroughly (making sure it didn't sit in water)... during this month more and more stems wilted, but again, most remained relatively healthy looking. Again I got rid of the dead branches. I let it sit for 1 more month and watered it again last week. But its not really getting any better? Today, I had to trim off another 3 yellowed stems and noticed that some stems' leaves are starting to lose their shine and are sagging. Am I watering it wrong? Too much? Is the soil too cheap? Is it too cold? Or perhaps enough light? And why do the stems look so thin compared to other people's ZZs? If anyone could lend me some wisdom I would be very grateful.
