I am new to this group. Last summer, I grew a big pot of catnip, which I make into tea to help me sleep. When it started to get cold, I brought the catnip indoors and put it in a south east facing window under a plant light. After a brief adjustment period, the catnip grew again.
Last month, when it got warm again, I put it back out on my deck in the sun. Last summer it thrived in this environment. However, the plant immediately wilted and died. This happened within 3 days or so. I watered it, but it was too late.
Does anybody have any idea what happened? I had to buy a new plant.
