Recently my mint has been looking less and less healthy. Here's what it looks like right now:
I made two changes since when it looked relatively healthy and when it started looking like this, which may be the culprit. First, I added a spoon of fertilizer, mixed with a cup of water. The instructions say to use two spoons for a pot of that size. Second, I started watering it every day. I suspect the second is more of a culprit, because when I tested the soil yesterday, and noticed that when I pressed down on it, water actually squeezed out the bottom of the pot. This was several hours after I'd watered it, so I'm guessing there isn't very good drainage.
I carefully removed the mint from the soil, which was easy, since the roots hadn't spread very far, and squeezed the excess water out of the soil. It was like ringing out a shirt after jumping into a lake with it. Then I broke up the soil to aerate it and replanted, and I haven't watered it today.
What, if anything, can be done to save this poor thing at this point?
