We had this gorgeous kafir lime plant in an indoor/outdoor pot. It's been on our front porch for 3 months or so, and on Saturday we finally moved it into the back yard for full sunlight. Our porch is open on the sides, so it's been getting indirect light.

We also gave it a citrus/fruit tree fertilizer pod.

The leaves turned bad the next day, so we moved it back on the front porch, and then probably over watered it for a couple of days. We also removed the fertilizer pod.

It seems to be deteriorating. On two of the longer branches there are now little black pods (they had probably been there for a while), and ants.

Any thoughts on what might have caused it (so many variables)? Any thoughts on remediation, or what clearly not to do (like probably don't repot right?).

Thanks for your help!
