Yesterday (Apr 9) I bought a fresh tuft of parsley at the supermarket, packed in a paper cone with its roots still wet. Never seen before, they claim it would stay fresh if properly treated.
So, having not a pot with drain holes, my last resort is a glass jar. I put some pebbles on the bottom, a layer of paper, and some soil, where I planted the parsley. I gave it a single spoon of water right on the center of the cluster of stems at morning and evening, to make sure that no nasty pile up of water on the bottom would cause root rotting. Unfortunately, my studio flat is not that lighty, and gets direct sunlight for some three hours a day.
After a single day, even if I am definitely not an expert, and never grew parsley before, having compared with some pictures I found on google (I am sorry for my bizarre approach to gardening), I reckon my parsley is begging for mercy and for a quick but painless death. I attach a picture to both scare you and let you understand what is wrong with it.
