I thought I had killed my ZZ plant last year but I moved it into a little more sun and pretty much stopped watering it completely. It gets some splash from the pot next to it and of course it gets a lot of rain in the summer. Yesterday I felt around inside and it was dry as a bone so I gave it a good watering and feel that should get it through to next year.
There are I think 3 new stems coming out, 2 of them are easy to see but there is another one that is smaller.
