Problem near a peace lily ...? my neighbor gave me one contained by a 2 gal container...

my neighbor gave me one contained by a 2 gal container -- it was derived from a larger lily she keep on a shaded back porch. it is very well developed, and even has a bloom. but the 8" leaves are drooping and are looking piqued (that's the track it was when she hand it over to me) ... until i can repot, i threw some time release fertilizer on the topsoil and have watered it ably.

neighbor said:
- it needed to be repotted into a bigger pot.
- she's watered it with miracle grow for fairly awhile
- it should be inside as it is too hot (central louisiana) to keep outdoors, even surrounded by the shade.

help? i don't wanna grant this plant more trauma than it's evidently already dealing with.
Answers:    Make sure the plant is within a large satisfactory pot. Also, be sure the pot has passable drainage. If it perks stern up after you water it, consequently it's not getting enough sea. If it's yellowing, and watering doesn't help, later you're probably over-watering it.

Don't fertilize it until it is doing better. Put it into a pot that's just nearly an inch and a half bigger adjectives around the original root orb. Don't forget to keep the plant at equal level next to respect to the soil as it was near the parent plant. Definitely keep it within bright light, but NOT surrounded by direct sun.

Good luck!
You said it came from a bigger lily? You also didn't mention how long you hold had it. So I am guessing that it may be wilted from shock. Keep the plant surrounded by the same pot. I would not fertilize the plant for something like a month - month and a half after transplanting. I would hold it moist but not wet during that month. Keep it surrounded by a shaded area resembling the parent plant but if the weather is really hot (90+) try to keep it contained by a cooler area for that 1 month convalescence. Trimming spinal column the flower and some of the leaves will help the plant recuperate as it wont have to put so much joie de vivre into flowers and failing leaves. After you see new growth I would transplant it to a contemporary pot. Good luck
