Pictures please

first .... go emu eagles ...

second.. fertilizer is RARELY a remedy ... and i would presume that a plant fresh from the grower is juiced to the max ... it is a tree .. not a child.. it doesnt need to be repeatedly fed...go easy with fert.. especially in winter ...

third ... as to the grower ... we have no idea what this plant went thru.. from grower to you ... so i would presume it is stressed ... from all the handling.. shipping.. etc ... nothing but time to settle down is required ...

4th ... i hope you didnt put it in full sun ... due to the stresses ... full bright shade would have been best.. hardening off to its new circumstances ...

5th .... down here.. 30 miles SE of you..; it has been in the lower 50s at night.. and tomorrow is predicted into the 40s.. its probably time to bring it in .... which will be more stress btw .... put it in a bright window ... but not direct sun ... again.. harden it off ... but it will need light in a few weeks ... [i do realize you are in the city.. so temps might be a bit warmer.. but it isnt time to roll the dice on that with a citrus in MI]

6th.. again.. its a tree.. things happen in slow motion ... i call it tree time ....not only problems... but getting over the problems... imo .. nothing is worse.. that repeatedly trying to fix the same problem.. for all you know ... you solved the problem the first time...

just be patient ... get it in the house ... and just let it settle down ...

the sun is in decline ... and some leaf loss on houseplants is not uncommon after you bring them indoors .. especially yours.. with all the stresses its been thru ... so do not continue to freak out.. with every leaf that falls off ... just let it settle down.. water it properly.. letting it near dry ... and you should be in the best situation you can be in.. trying to grow a indoors ....

lastly.. if you have a forced air furnace.. humidity indoors in winter.. could be a big problem ... especially since there is usually a furnace vent near the window you need for light ... you might have to figure that all out .... one thing for sure... figure out how to avoid direct hot air blowing the plant .... you will dry out the leaves.. and they might fall off ...

ps: im not to sure from your facts.. if you also repotted it ... and if you did.. that was another huge stress ... welcome to the forums ....

Sorry about the photo. I tried adding it a handful of times, but it would never work.

Ken,

Thanks for your comments.

Like I said, it was a light application.

I repotted it right after it arrived, and kept it in shade for a while after. It had a lot of new growth that grew quickly and all looked really healthy, so I think it was feeling really good at that point. There were no signs of stress.

Concerning weather... I don't know what forecast you're seeing. The past few days have had lows in the 60s, and it looks like it will continue in the mid 50's, low to mid 60s for the next couple of weeks. I will keep an eye on the weather, though, and probably bring it in somewhat soon. But my meyer lemon tree that is right next to the lime (can see in photo) isn't having leaf drop. So that makes me think it's not as environment related.

Keep in mind that a meyer lemon can withstand lower temps than a persian lime can. Not that low 60's/high 50's would be an issue for the lime, but as it gets lower they meyer is much more cold hardy. It is not uncommon for citrus to drop leaves when light levels are lowered as mother nature has been doing lately.

There were no signs of stress.

==>>>

you didnt mention prior experience ... and that is always a plus ...

yes there was signs of stress .. leaves fell off ...

to repeat.. and maybe clarify ... IN TREE TIME... the insult/injury could have happened when the grower shipped it.. when the seller received it... when he boxed it to ship to you ... or trucked it.. etc...etc...

frankly.. it looks great right now ... so just relax ...

it was my phone weather app .. like i said.. rural can be very different than the city ... but it will come to you ... it doesnt need more stress ... at a min.... put it near the house.. as that heat sink will keep it a few degrees warmer... should ma nature mess with you ...

Any supposed injury during the above quotation, has nothing to do with the leaves falling at the writing of Tyler's post. As Tyler wrote in is post ..."lot of new growth that grew quickly"... trees putting on new flushes of growth are not trees in stress.
